What Is Quantitative Research? | Definition, Uses & Methods

Published on June 12, 2020 by Pritha Bhandari . Revised on June 22, 2023.

Quantitative research is the process of collecting and analyzing numerical data. It can be used to find patterns and averages, make predictions, test causal relationships, and generalize results to wider populations.

Quantitative research is the opposite of qualitative research , which involves collecting and analyzing non-numerical data (e.g., text, video, or audio).

Quantitative research is widely used in the natural and social sciences: biology, chemistry, psychology, economics, sociology, marketing, etc.

  • What is the demographic makeup of Singapore in 2020?
  • How has the average temperature changed globally over the last century?
  • Does environmental pollution affect the prevalence of honey bees?
  • Does working from home increase productivity for people with long commutes?

You can use quantitative research methods for descriptive, correlational or experimental research.

  • In descriptive research , you simply seek an overall summary of your study variables.
  • In correlational research , you investigate relationships between your study variables.
  • In experimental research , you systematically examine whether there is a cause-and-effect relationship between variables.

Correlational and experimental research can both be used to formally test hypotheses , or predictions, using statistics. The results may be generalized to broader populations based on the sampling method used.

To collect quantitative data, you will often need to use operational definitions that translate abstract concepts (e.g., mood) into observable and quantifiable measures (e.g., self-ratings of feelings and energy levels).

Note that quantitative research is at risk for certain research biases , including information bias , omitted variable bias , sampling bias , or selection bias . Be sure that you’re aware of potential biases as you collect and analyze your data to prevent them from impacting your work too much.

Once data is collected, you may need to process it before it can be analyzed. For example, survey and test data may need to be transformed from words to numbers. Then, you can use statistical analysis to answer your research questions .

Descriptive statistics will give you a summary of your data and include measures of averages and variability. You can also use graphs, scatter plots and frequency tables to visualize your data and check for any trends or outliers.

Using inferential statistics , you can make predictions or generalizations based on your data. You can test your hypothesis or use your sample data to estimate the population parameter .

First, you use descriptive statistics to get a summary of the data. You find the mean (average) and the mode (most frequent rating) of procrastination of the two groups, and plot the data to see if there are any outliers.

You can also assess the reliability and validity of your data collection methods to indicate how consistently and accurately your methods actually measured what you wanted them to.

Quantitative research is often used to standardize data collection and generalize findings . Strengths of this approach include:

  • Replication

Repeating the study is possible because of standardized data collection protocols and tangible definitions of abstract concepts.

  • Direct comparisons of results

The study can be reproduced in other cultural settings, times or with different groups of participants. Results can be compared statistically.

  • Large samples

Data from large samples can be processed and analyzed using reliable and consistent procedures through quantitative data analysis.

  • Hypothesis testing

Using formalized and established hypothesis testing procedures means that you have to carefully consider and report your research variables, predictions, data collection and testing methods before coming to a conclusion.

Despite the benefits of quantitative research, it is sometimes inadequate in explaining complex research topics. Its limitations include:

  • Superficiality

Using precise and restrictive operational definitions may inadequately represent complex concepts. For example, the concept of mood may be represented with just a number in quantitative research, but explained with elaboration in qualitative research.

  • Narrow focus

Predetermined variables and measurement procedures can mean that you ignore other relevant observations.

  • Structural bias

Despite standardized procedures, structural biases can still affect quantitative research. Missing data , imprecise measurements or inappropriate sampling methods are biases that can lead to the wrong conclusions.

  • Lack of context

Quantitative research often uses unnatural settings like laboratories or fails to consider historical and cultural contexts that may affect data collection and results.

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to systematically measure variables and test hypotheses . Qualitative methods allow you to explore concepts and experiences in more detail.

In mixed methods research , you use both qualitative and quantitative data collection and analysis methods to answer your research question .

Data collection is the systematic process by which observations or measurements are gathered in research. It is used in many different contexts by academics, governments, businesses, and other organizations.

Operationalization means turning abstract conceptual ideas into measurable observations.

For example, the concept of social anxiety isn’t directly observable, but it can be operationally defined in terms of self-rating scores, behavioral avoidance of crowded places, or physical anxiety symptoms in social situations.

Before collecting data , it’s important to consider how you will operationalize the variables that you want to measure.

Reliability and validity are both about how well a method measures something:

  • Reliability refers to the  consistency of a measure (whether the results can be reproduced under the same conditions).
  • Validity   refers to the  accuracy of a measure (whether the results really do represent what they are supposed to measure).

If you are doing experimental research, you also have to consider the internal and external validity of your experiment.

Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. It is used by scientists to test specific predictions, called hypotheses , by calculating how likely it is that a pattern or relationship between variables could have arisen by chance.

What is Quantitative Research Design?

Types of quantitative research design, quantitative research design methods, quantitative research design process: 10 key steps, top 11 best practices for quantitative research design.

Quantitative research design is defined as a research method used in various disciplines, including social sciences, psychology, economics, and market research. It aims to collect and analyze numerical data to answer research questions and test hypotheses.

Quantitative research design offers several advantages, including the ability to generalize findings to larger populations, the potential for statistical analysis and hypothesis testing, and the capacity to uncover patterns and relationships among variables. However, it also has limitations, such as the potential for oversimplification of complex phenomena and the reliance on predetermined categories and measurements.

Quantitative research design key elements

Quantitative research design typically follows a systematic and structured approach. It involves the following key elements:

  • Research Question: The researcher formulates a clear and specific question that can be answered through quantitative research . The question should be measurable and objective
  • Variables: The researcher identifies and defines the variables relevant to the research question. Variables are attributes or characteristics that can be measured or observed. They can be independent variables (factors that are manipulated or controlled) or dependent variables (outcomes or responses that are measured).
  • Hypotheses: The researcher develops one or more hypotheses based on the research question. Hypotheses are verifiable statements that make predictions about the association between variables.
  • Sampling: The researcher determines the target population and selects a representative sample from that population. The sample should be large enough to provide statistically significant results and should be chosen using appropriate sampling techniques.
  • Data Collection: Quantitative research design relies on the collection of numerical data. This can be done through various methods such as surveys, experiments, quantitative observations , or secondary data analysis. Standardized instruments, such as questionnaires or scales, are often used to ensure consistency and reliability.
  • Data Analysis: The collected data is analyzed using statistical methods and techniques. Descriptive statistics are used to summarize and describe the data, while inferential statistics are used to draw conclusions and make generalizations about the population based on the sample data.
  • Results and Conclusions: The researcher interprets the findings and draws conclusions based on the analysis. The results are typically presented in the form of tables, graphs, and statistical measures, such as means, correlations, or regression coefficients.

Types of Quantitative Research Design

There are several types of quantitative research designs, each suited for different research purposes and questions. Here are some common types of quantitative research designs:

  • Experimental Design

Experimental design involves the manipulation of an independent variable to observe its effect on a dependent variable while controlling for other variables. Participants are typically randomly assigned to different groups, such as a control group and one or more experimental groups, to compare the outcomes. This approach enables the establishment of cause-and-effect relationships.

  • Quasi-Experimental Design

Quasi-experimental design exhibits similarities to experimental design, yet it lacks the random assignment of participants to groups. The researcher takes advantage of naturally occurring groups or pre-existing conditions to compare the effects of an independent variable on a dependent variable. While it doesn’t establish causality as strongly as experimental design, it can still provide valuable insights.

  • Survey Research

Survey research involves collecting data through questionnaires or interviews administered to a sample of participants. Surveys allow researchers to gather data on a wide range of variables and can be conducted in various settings, such as online surveys or face-to-face interviews. This design is particularly useful for studying attitudes, opinions, and behaviors within a population.

  • Correlational Design

The correlational design investigates the association between two or more variables without engaging in their manipulation. Researchers measure variables and determine the degree and direction of their association using statistical techniques such as correlation analysis. However, correlational research cannot establish causality, only the strength and direction of the relationship.

  • Longitudinal Design

Longitudinal design involves collecting data from the same individuals or groups over an extended period. This design allows researchers to study changes and patterns over time, providing insights into the stability and development of variables. Longitudinal studies can be conducted retrospectively (looking back) or prospectively (following participants into the future).

  • Cross-sectional Design

Cross-sectional design collects data from a specific population at a single point in time. Researchers examine different variables simultaneously and analyze the relationships among them. This design is often used to gather data quickly and assess the prevalence of certain characteristics or behaviors within a population.

  • Ex post facto Design

Ex post facto design involves studying the effects of an independent variable that is beyond the researcher’s control. The researcher selects participants based on their exposure to the independent variable, collecting data retrospectively. This design is useful when random assignment or manipulation of variables is not feasible or ethical.

Quantitative research design methods refer to the specific techniques and approaches used to collect and analyze numerical data in quantitative research . Below are several commonly utilized quantitative research methods:

  • Surveys: Surveys involve administering questionnaires or structured interviews to gather data from a sample of participants. Surveys can be implemented through different channels, such as conducting them in person, over the phone, via mail, or utilizing online platforms. Researchers use various question types, such as multiple-choice, Likert scales, or rating scales, to collect quantitative data on attitudes, opinions, behaviors, and demographics.
  • Experiments: Experiments involve manipulating one or more independent variables and measuring their effects on dependent variables. To compare outcomes, participants are assigned randomly to various groups, including control and experimental groups. Experimental designs allow researchers to establish cause-and-effect relationships by controlling for confounding factors.
  • Observational Studies: Observational studies involve systematically observing and recording behavior, events, or phenomena in natural settings. Researchers can use structured or unstructured quantitative observation methods , depending on the research objectives. Quantitative data can be collected by counting the frequency of specific behaviors or by using coding systems to categorize and analyze observed data.
  • Archival Research: Archival research involves analyzing existing data collected for purposes other than the current study. Researchers may use historical documents, government records, public databases, or organizational records to extract data through quantitative research . Archival research allows for large-scale data analysis and can provide insights into long-term trends and patterns.
  • Secondary Data Analysis: Similar to archival research, secondary data analysis involves using existing datasets that were collected by other researchers or organizations. Researchers analyze the data to answer new research questions or test different hypotheses. Secondary data sources can include government surveys, social surveys, or market research data.
  • Content Analysis: Content analysis is a method used to analyze textual or visual data to identify patterns, themes, or relationships. Researchers code and categorize the content of documents, interviews, articles, or media sources. The coded data is then quantified and statistically analyzed to draw conclusions. Content analysis can be both qualitative and quantitative , depending on the approach used.
  • Psychometric Testing: Psychometric testing involves the development and administration of tests or scales to measure psychological constructs, such as intelligence, personality traits, or attitudes. Researchers use statistical techniques to analyze the test data, such as factor analysis, reliability analysis, or item response theory.

Consider factors such as feasibility, ethical considerations, and resources available.

4. Define Variables and Hypotheses

Identify the variables that are pertinent to your research question. Clearly define each variable and its operational definitions (how they will be measured or observed). Develop hypotheses that state the expected relationships between variables based on existing theories or prior research.

5. Determine Sampling Strategy

Define the target population for your study and determine the sampling strategy. Decide on the sample size and the sampling method (e.g., random sampling, stratified sampling, convenience sampling). Ensure that your sample is representative of the population you want to generalize your findings to.

6. Select Data Collection Methods

Choose the appropriate data collection methods to gather data through quantitative research . This can include surveys, experiments, observations, or secondary data analysis. Develop or select validated instruments (e.g., questionnaires, scales) for data collection. Perform a pilot test on the instruments to ensure their reliability and validity.

7. Collect Data

Implement your data collection plan. Administer surveys, conduct experiments, observe participants, or extract data from existing sources. Ensure proper data management and organization to maintain accuracy and integrity. Consider ethical considerations and obtain necessary permissions or approvals.

8. Analyze Data

Perform data analysis using appropriate statistical techniques. Depending on your research design and data characteristics, apply descriptive statistics (e.g., means, frequencies) and inferential statistics (e.g., t-tests, ANOVA, regression analysis) to analyze relationships, test hypotheses, and draw conclusions. Use statistical software for efficient and accurate analysis.

9. Interpret Results

Interpret the findings of your data analysis. Examine statistical outputs, identify significant relationships or patterns, and relate them to your research question and hypotheses. Consider the limitations of your study and address any unexpected or contradictory results.

Quantitative Research

Quantitative research is a type of research that collects and analyzes numerical data to test hypotheses and answer research questions . This research typically involves a large sample size and uses statistical analysis to make inferences about a population based on the data collected. It often involves the use of surveys, experiments, or other structured data collection methods to gather quantitative data.

Quantitative Research Methods

Quantitative Research Methods

Quantitative Research Methods are as follows:

Descriptive Research Design

Descriptive research design is used to describe the characteristics of a population or phenomenon being studied. This research method is used to answer the questions of what, where, when, and how. Descriptive research designs use a variety of methods such as observation, case studies, and surveys to collect data. The data is then analyzed using statistical tools to identify patterns and relationships.

Correlational Research Design

Correlational research design is used to investigate the relationship between two or more variables. Researchers use correlational research to determine whether a relationship exists between variables and to what extent they are related. This research method involves collecting data from a sample and analyzing it using statistical tools such as correlation coefficients.

Quasi-experimental Research Design

Quasi-experimental research design is used to investigate cause-and-effect relationships between variables. This research method is similar to experimental research design, but it lacks full control over the independent variable. Researchers use quasi-experimental research designs when it is not feasible or ethical to manipulate the independent variable.

Experimental Research Design

Experimental research design is used to investigate cause-and-effect relationships between variables. This research method involves manipulating the independent variable and observing the effects on the dependent variable. Researchers use experimental research designs to test hypotheses and establish cause-and-effect relationships.

Survey Research

Survey research involves collecting data from a sample of individuals using a standardized questionnaire. This research method is used to gather information on attitudes, beliefs, and behaviors of individuals. Researchers use survey research to collect data quickly and efficiently from a large sample size. Survey research can be conducted through various methods such as online, phone, mail, or in-person interviews.

Quantitative Research Analysis Methods

Here are some commonly used quantitative research analysis methods:

Statistical Analysis

Statistical analysis is the most common quantitative research analysis method. It involves using statistical tools and techniques to analyze the numerical data collected during the research process. Statistical analysis can be used to identify patterns, trends, and relationships between variables, and to test hypotheses and theories.

Regression Analysis

Regression analysis is a statistical technique used to analyze the relationship between one dependent variable and one or more independent variables. Researchers use regression analysis to identify and quantify the impact of independent variables on the dependent variable.

Factor Analysis

Factor analysis is a statistical technique used to identify underlying factors that explain the correlations among a set of variables. Researchers use factor analysis to reduce a large number of variables to a smaller set of factors that capture the most important information.

Structural Equation Modeling

Structural equation modeling is a statistical technique used to test complex relationships between variables. It involves specifying a model that includes both observed and unobserved variables, and then using statistical methods to test the fit of the model to the data.

Time Series Analysis

Time series analysis is a statistical technique used to analyze data that is collected over time. It involves identifying patterns and trends in the data, as well as any seasonal or cyclical variations.

Multilevel Modeling

Multilevel modeling is a statistical technique used to analyze data that is nested within multiple levels. For example, researchers might use multilevel modeling to analyze data that is collected from individuals who are nested within groups, such as students nested within schools.

Applications of Quantitative Research

Quantitative research has many applications across a wide range of fields. Here are some common examples:

  • Market Research : Quantitative research is used extensively in market research to understand consumer behavior, preferences, and trends.

  • Political Science: A team of researchers conducts a study to investigate voter behavior during an election. They use survey methods to collect data on voting patterns, demographics, and political attitudes, and analyze the results using statistical methods.

How to Conduct Quantitative Research

Here is a general overview of how to conduct quantitative research:

  • Develop a research question: The first step in conducting quantitative research is to develop a clear and specific research question. This question should be based on a gap in existing knowledge, and should be answerable using quantitative methods.
  • Develop a research design: Once you have a research question, you will need to develop a research design. This involves deciding on the appropriate methods to collect data, such as surveys, experiments, or observational studies. You will also need to determine the appropriate sample size, data collection instruments, and data analysis techniques.
  • Collect data: The next step is to collect data. This may involve administering surveys or questionnaires, conducting experiments, or gathering data from existing sources. It is important to use standardized methods to ensure that the data is reliable and valid.
  • Analyze data : Once the data has been collected, it is time to analyze it. This involves using statistical methods to identify patterns, trends, and relationships between variables. Common statistical techniques include correlation analysis, regression analysis, and hypothesis testing.
  • Interpret results: After analyzing the data, you will need to interpret the results. This involves identifying the key findings, determining their significance, and drawing conclusions based on the data.
  • Communicate findings: Finally, you will need to communicate your findings. This may involve writing a research report, presenting at a conference, or publishing in a peer-reviewed journal. It is important to clearly communicate the research question, methods, results, and conclusions to ensure that others can understand and replicate your research.

When to use Quantitative Research

Here are some situations when quantitative research can be appropriate:

  • To test a hypothesis: Quantitative research is often used to test a hypothesis or a theory. It involves collecting numerical data and using statistical analysis to determine if the data supports or refutes the hypothesis.
  • To generalize findings: If you want to generalize the findings of your study to a larger population, quantitative research can be useful. This is because it allows you to collect numerical data from a representative sample of the population and use statistical analysis to make inferences about the population as a whole.
  • To measure relationships between variables: If you want to measure the relationship between two or more variables, such as the relationship between age and income, or between education level and job satisfaction, quantitative research can be useful. It allows you to collect numerical data on both variables and use statistical analysis to determine the strength and direction of the relationship.
  • To identify patterns or trends: Quantitative research can be useful for identifying patterns or trends in data. For example, you can use quantitative research to identify trends in consumer behavior or to identify patterns in stock market data.
  • To quantify attitudes or opinions : If you want to measure attitudes or opinions on a particular topic, quantitative research can be useful. It allows you to collect numerical data using surveys or questionnaires and analyze the data using statistical methods to determine the prevalence of certain attitudes or opinions.

Purpose of Quantitative Research

The purpose of quantitative research is to systematically investigate and measure the relationships between variables or phenomena using numerical data and statistical analysis. The main objectives of quantitative research include:

  • Description : To provide a detailed and accurate description of a particular phenomenon or population.
  • Explanation : To explain the reasons for the occurrence of a particular phenomenon, such as identifying the factors that influence a behavior or attitude.
  • Prediction : To predict future trends or behaviors based on past patterns and relationships between variables.
  • Control : To identify the best strategies for controlling or influencing a particular outcome or behavior.

Quantitative research is used in many different fields, including social sciences, business, engineering, and health sciences. It can be used to investigate a wide range of phenomena, from human behavior and attitudes to physical and biological processes. The purpose of quantitative research is to provide reliable and valid data that can be used to inform decision-making and improve understanding of the world around us.

Advantages of Quantitative Research

There are several advantages of quantitative research, including:

  • Objectivity : Quantitative research is based on objective data and statistical analysis, which reduces the potential for bias or subjectivity in the research process.
  • Reproducibility : Because quantitative research involves standardized methods and measurements, it is more likely to be reproducible and reliable.
  • Generalizability : Quantitative research allows for generalizations to be made about a population based on a representative sample, which can inform decision-making and policy development.
  • Precision : Quantitative research allows for precise measurement and analysis of data, which can provide a more accurate understanding of phenomena and relationships between variables.
  • Efficiency : Quantitative research can be conducted relatively quickly and efficiently, especially when compared to qualitative research, which may involve lengthy data collection and analysis.
  • Large sample sizes : Quantitative research can accommodate large sample sizes, which can increase the representativeness and generalizability of the results.

Limitations of Quantitative Research

There are several limitations of quantitative research, including:

  • Limited understanding of context: Quantitative research typically focuses on numerical data and statistical analysis, which may not provide a comprehensive understanding of the context or underlying factors that influence a phenomenon.
  • Simplification of complex phenomena: Quantitative research often involves simplifying complex phenomena into measurable variables, which may not capture the full complexity of the phenomenon being studied.
  • Potential for researcher bias: Although quantitative research aims to be objective, there is still the potential for researcher bias in areas such as sampling, data collection, and data analysis.
  • Limited ability to explore new ideas: Quantitative research is often based on pre-determined research questions and hypotheses, which may limit the ability to explore new ideas or unexpected findings.
  • Limited ability to capture subjective experiences : Quantitative research is typically focused on objective data and may not capture the subjective experiences of individuals or groups being studied.
  • Ethical concerns : Quantitative research may raise ethical concerns, such as invasion of privacy or the potential for harm to participants.

Quantitative methodology is the dominant research framework in the social sciences. It refers to a set of strategies, techniques and assumptions used to study psychological, social and economic processes through the exploration of numeric patterns . Quantitative research gathers a range of numeric data. Some of the numeric data is intrinsically quantitative (e.g. personal income), while in other cases the numeric structure is  imposed (e.g. ‘On a scale from 1 to 10, how depressed did you feel last week?’). The collection of quantitative information allows researchers to conduct simple to extremely sophisticated statistical analyses that aggregate the data (e.g. averages, percentages), show relationships among the data (e.g. ‘Students with lower grade point averages tend to score lower on a depression scale’) or compare across aggregated data (e.g. the USA has a higher gross domestic product than Spain). Quantitative research includes methodologies such as questionnaires, structured observations or experiments and stands in contrast to qualitative research. Qualitative research involves the collection and analysis of narratives and/or open-ended observations through methodologies such as interviews, focus groups or ethnographies.

What is the purpose of quantitative research?

The purpose of quantitative research is to generate knowledge and create understanding about the social world. Quantitative research is used by social scientists, including communication researchers, to observe phenomena or occurrences affecting individuals. Social scientists are concerned with the study of people. Quantitative research is a way to learn about a particular group of people, known as a sample population. Using scientific inquiry, quantitative research relies on data that are observed or measured to examine questions about the sample population.

What Is Quantitative Research? | Definition & Methods

Published on 4 April 2022 by Pritha Bhandari . Revised on 10 October 2022.

Quantitative research is the process of collecting and analysing numerical data. It can be used to find patterns and averages, make predictions, test causal relationships, and generalise results to wider populations.

Quantitative research is the opposite of qualitative research , which involves collecting and analysing non-numerical data (e.g. text, video, or audio).

Quantitative research is widely used in the natural and social sciences: biology, chemistry, psychology, economics, sociology, marketing, etc.

  • How has the average temperature changed globally over the last century?
  • Does environmental pollution affect the prevalence of honey bees?
  • Does working from home increase productivity for people with long commutes?

Table of contents

Quantitative research methods, quantitative data analysis, advantages of quantitative research, disadvantages of quantitative research, frequently asked questions about quantitative research.

You can use quantitative research methods for descriptive, correlational or experimental research.

  • In descriptive research , you simply seek an overall summary of your study variables.
  • In correlational research , you investigate relationships between your study variables.
  • In experimental research , you systematically examine whether there is a cause-and-effect relationship between variables.

Correlational and experimental research can both be used to formally test hypotheses , or predictions, using statistics. The results may be generalised to broader populations based on the sampling method used.

To collect quantitative data, you will often need to use operational definitions that translate abstract concepts (e.g., mood) into observable and quantifiable measures (e.g., self-ratings of feelings and energy levels).

Prevent plagiarism, run a free check.

Once data is collected, you may need to process it before it can be analysed. For example, survey and test data may need to be transformed from words to numbers. Then, you can use statistical analysis to answer your research questions .

Descriptive statistics will give you a summary of your data and include measures of averages and variability. You can also use graphs, scatter plots and frequency tables to visualise your data and check for any trends or outliers.

Using inferential statistics , you can make predictions or generalisations based on your data. You can test your hypothesis or use your sample data to estimate the population parameter .

You can also assess the reliability and validity of your data collection methods to indicate how consistently and accurately your methods actually measured what you wanted them to.

Quantitative research is often used to standardise data collection and generalise findings . Strengths of this approach include:

  • Replication

Repeating the study is possible because of standardised data collection protocols and tangible definitions of abstract concepts.

  • Direct comparisons of results

The study can be reproduced in other cultural settings, times or with different groups of participants. Results can be compared statistically.

  • Large samples

Data from large samples can be processed and analysed using reliable and consistent procedures through quantitative data analysis.

  • Hypothesis testing

Using formalised and established hypothesis testing procedures means that you have to carefully consider and report your research variables, predictions, data collection and testing methods before coming to a conclusion.

Despite the benefits of quantitative research, it is sometimes inadequate in explaining complex research topics. Its limitations include:

  • Superficiality

Using precise and restrictive operational definitions may inadequately represent complex concepts. For example, the concept of mood may be represented with just a number in quantitative research, but explained with elaboration in qualitative research.

  • Narrow focus

Predetermined variables and measurement procedures can mean that you ignore other relevant observations.

  • Structural bias

Despite standardised procedures, structural biases can still affect quantitative research. Missing data , imprecise measurements or inappropriate sampling methods are biases that can lead to the wrong conclusions.

  • Lack of context

Quantitative research often uses unnatural settings like laboratories or fails to consider historical and cultural contexts that may affect data collection and results.

Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Quantitative methods allow you to test a hypothesis by systematically collecting and analysing data, while qualitative methods allow you to explore ideas and experiences in depth.

In mixed methods research , you use both qualitative and quantitative data collection and analysis methods to answer your research question .

Data collection is the systematic process by which observations or measurements are gathered in research. It is used in many different contexts by academics, governments, businesses, and other organisations.

Operationalisation means turning abstract conceptual ideas into measurable observations.

For example, the concept of social anxiety isn’t directly observable, but it can be operationally defined in terms of self-rating scores, behavioural avoidance of crowded places, or physical anxiety symptoms in social situations.

Before collecting data , it’s important to consider how you will operationalise the variables that you want to measure.

Reliability and validity are both about how well a method measures something:

  • Reliability refers to the  consistency of a measure (whether the results can be reproduced under the same conditions).
  • Validity   refers to the  accuracy of a measure (whether the results really do represent what they are supposed to measure).

If you are doing experimental research , you also have to consider the internal and external validity of your experiment.

Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. It is used by scientists to test specific predictions, called hypotheses , by calculating how likely it is that a pattern or relationship between variables could have arisen by chance.

Quantitative research methods

a method of research that relies on measuring variables using a numerical system, analyzing these measurements using any of a variety of statistical models, and reporting relationships and associations among the studied variables. For example, these variables may be test scores or measurements of reaction time. The goal of gathering this quantitative data is to understand, describe, and predict the nature of a phenomenon, particularly through the development of models and theories. Quantitative research techniques include experiments and surveys.

The development of research questions and the subsequent hypotheses are prerequisites to defining the main research purpose and specific objectives of a study. Consequently, these objectives determine the study design and research outcome. The development of research questions is a process based on knowledge of current trends, cutting-edge studies, and technological advances in the research field. Excellent research questions are focused and require a comprehensive literature search and in-depth understanding of the problem being investigated. Initially, research questions may be written as descriptive questions which could be developed into inferential questions. These questions must be specific and concise to provide a clear foundation for developing hypotheses. Hypotheses are more formal predictions about the research outcomes. These specify the possible results that may or may not be expected regarding the relationship between groups. Thus, research questions and hypotheses clarify the main purpose and specific objectives of the study, which in turn dictate the design of the study, its direction, and outcome. Studies developed from good research questions and hypotheses will have trustworthy outcomes with wide-ranging social and health implications.

INTRODUCTION

Scientific research is usually initiated by posing evidenced-based research questions which are then explicitly restated as hypotheses. 1 , 2 The hypotheses provide directions to guide the study, solutions, explanations, and expected results. 3 , 4 Both research questions and hypotheses are essentially formulated based on conventional theories and real-world processes, which allow the inception of novel studies and the ethical testing of ideas. 5 , 6

It is crucial to have knowledge of both quantitative and qualitative research 2 as both types of research involve writing research questions and hypotheses. 7 However, these crucial elements of research are sometimes overlooked; if not overlooked, then framed without the forethought and meticulous attention it needs. Planning and careful consideration are needed when developing quantitative or qualitative research, particularly when conceptualizing research questions and hypotheses. 4

There is a continuing need to support researchers in the creation of innovative research questions and hypotheses, as well as for journal articles that carefully review these elements. 1 When research questions and hypotheses are not carefully thought of, unethical studies and poor outcomes usually ensue. Carefully formulated research questions and hypotheses define well-founded objectives, which in turn determine the appropriate design, course, and outcome of the study. This article then aims to discuss in detail the various aspects of crafting research questions and hypotheses, with the goal of guiding researchers as they develop their own. Examples from the authors and peer-reviewed scientific articles in the healthcare field are provided to illustrate key points.

DEFINITIONS AND RELATIONSHIP OF RESEARCH QUESTIONS AND HYPOTHESES

A research question is what a study aims to answer after data analysis and interpretation. The answer is written in length in the discussion section of the paper. Thus, the research question gives a preview of the different parts and variables of the study meant to address the problem posed in the research question. 1 An excellent research question clarifies the research writing while facilitating understanding of the research topic, objective, scope, and limitations of the study. 5

On the other hand, a research hypothesis is an educated statement of an expected outcome. This statement is based on background research and current knowledge. 8 , 9 The research hypothesis makes a specific prediction about a new phenomenon 10 or a formal statement on the expected relationship between an independent variable and a dependent variable. 3 , 11 It provides a tentative answer to the research question to be tested or explored. 4

Hypotheses employ reasoning to predict a theory-based outcome. 10 These can also be developed from theories by focusing on components of theories that have not yet been observed. 10 The validity of hypotheses is often based on the testability of the prediction made in a reproducible experiment. 8

Conversely, hypotheses can also be rephrased as research questions. Several hypotheses based on existing theories and knowledge may be needed to answer a research question. Developing ethical research questions and hypotheses creates a research design that has logical relationships among variables. These relationships serve as a solid foundation for the conduct of the study. 4 , 11 Haphazardly constructed research questions can result in poorly formulated hypotheses and improper study designs, leading to unreliable results. Thus, the formulations of relevant research questions and verifiable hypotheses are crucial when beginning research. 12

CHARACTERISTICS OF GOOD RESEARCH QUESTIONS AND HYPOTHESES

Excellent research questions are specific and focused. These integrate collective data and observations to confirm or refute the subsequent hypotheses. Well-constructed hypotheses are based on previous reports and verify the research context. These are realistic, in-depth, sufficiently complex, and reproducible. More importantly, these hypotheses can be addressed and tested. 13

There are several characteristics of well-developed hypotheses. Good hypotheses are 1) empirically testable 7 , 10 , 11 , 13 ; 2) backed by preliminary evidence 9 ; 3) testable by ethical research 7 , 9 ; 4) based on original ideas 9 ; 5) have evidenced-based logical reasoning 10 ; and 6) can be predicted. 11 Good hypotheses can infer ethical and positive implications, indicating the presence of a relationship or effect relevant to the research theme. 7 , 11 These are initially developed from a general theory and branch into specific hypotheses by deductive reasoning. In the absence of a theory to base the hypotheses, inductive reasoning based on specific observations or findings form more general hypotheses. 10

TYPES OF RESEARCH QUESTIONS AND HYPOTHESES

Research questions and hypotheses are developed according to the type of research, which can be broadly classified into quantitative and qualitative research. We provide a summary of the types of research questions and hypotheses under quantitative and qualitative research categories in Table 1 .

Research questions in quantitative research

In quantitative research, research questions inquire about the relationships among variables being investigated and are usually framed at the start of the study. These are precise and typically linked to the subject population, dependent and independent variables, and research design. 1 Research questions may also attempt to describe the behavior of a population in relation to one or more variables, or describe the characteristics of variables to be measured ( descriptive research questions ). 1 , 5 , 14 These questions may also aim to discover differences between groups within the context of an outcome variable ( comparative research questions ), 1 , 5 , 14 or elucidate trends and interactions among variables ( relationship research questions ). 1 , 5 We provide examples of descriptive, comparative, and relationship research questions in quantitative research in Table 2 .

Hypotheses in quantitative research

In quantitative research, hypotheses predict the expected relationships among variables. 15 Relationships among variables that can be predicted include 1) between a single dependent variable and a single independent variable ( simple hypothesis ) or 2) between two or more independent and dependent variables ( complex hypothesis ). 4 , 11 Hypotheses may also specify the expected direction to be followed and imply an intellectual commitment to a particular outcome ( directional hypothesis ) 4 . On the other hand, hypotheses may not predict the exact direction and are used in the absence of a theory, or when findings contradict previous studies ( non-directional hypothesis ). 4 In addition, hypotheses can 1) define interdependency between variables ( associative hypothesis ), 4 2) propose an effect on the dependent variable from manipulation of the independent variable ( causal hypothesis ), 4 3) state a negative relationship between two variables ( null hypothesis ), 4 , 11 , 15 4) replace the working hypothesis if rejected ( alternative hypothesis ), 15 explain the relationship of phenomena to possibly generate a theory ( working hypothesis ), 11 5) involve quantifiable variables that can be tested statistically ( statistical hypothesis ), 11 6) or express a relationship whose interlinks can be verified logically ( logical hypothesis ). 11 We provide examples of simple, complex, directional, non-directional, associative, causal, null, alternative, working, statistical, and logical hypotheses in quantitative research, as well as the definition of quantitative hypothesis-testing research in Table 3 .

Research questions in qualitative research

Unlike research questions in quantitative research, research questions in qualitative research are usually continuously reviewed and reformulated. The central question and associated subquestions are stated more than the hypotheses. 15 The central question broadly explores a complex set of factors surrounding the central phenomenon, aiming to present the varied perspectives of participants. 15

There are varied goals for which qualitative research questions are developed. These questions can function in several ways, such as to 1) identify and describe existing conditions ( contextual research question s); 2) describe a phenomenon ( descriptive research questions ); 3) assess the effectiveness of existing methods, protocols, theories, or procedures ( evaluation research questions ); 4) examine a phenomenon or analyze the reasons or relationships between subjects or phenomena ( explanatory research questions ); or 5) focus on unknown aspects of a particular topic ( exploratory research questions ). 5 In addition, some qualitative research questions provide new ideas for the development of theories and actions ( generative research questions ) or advance specific ideologies of a position ( ideological research questions ). 1 Other qualitative research questions may build on a body of existing literature and become working guidelines ( ethnographic research questions ). Research questions may also be broadly stated without specific reference to the existing literature or a typology of questions ( phenomenological research questions ), may be directed towards generating a theory of some process ( grounded theory questions ), or may address a description of the case and the emerging themes ( qualitative case study questions ). 15 We provide examples of contextual, descriptive, evaluation, explanatory, exploratory, generative, ideological, ethnographic, phenomenological, grounded theory, and qualitative case study research questions in qualitative research in Table 4 , and the definition of qualitative hypothesis-generating research in Table 5 .

Qualitative studies usually pose at least one central research question and several subquestions starting with How or What . These research questions use exploratory verbs such as explore or describe . These also focus on one central phenomenon of interest, and may mention the participants and research site. 15

Hypotheses in qualitative research

Hypotheses in qualitative research are stated in the form of a clear statement concerning the problem to be investigated. Unlike in quantitative research where hypotheses are usually developed to be tested, qualitative research can lead to both hypothesis-testing and hypothesis-generating outcomes. 2 When studies require both quantitative and qualitative research questions, this suggests an integrative process between both research methods wherein a single mixed-methods research question can be developed. 1

FRAMEWORKS FOR DEVELOPING RESEARCH QUESTIONS AND HYPOTHESES

Research questions followed by hypotheses should be developed before the start of the study. 1 , 12 , 14 It is crucial to develop feasible research questions on a topic that is interesting to both the researcher and the scientific community. This can be achieved by a meticulous review of previous and current studies to establish a novel topic. Specific areas are subsequently focused on to generate ethical research questions. The relevance of the research questions is evaluated in terms of clarity of the resulting data, specificity of the methodology, objectivity of the outcome, depth of the research, and impact of the study. 1 , 5 These aspects constitute the FINER criteria (i.e., Feasible, Interesting, Novel, Ethical, and Relevant). 1 Clarity and effectiveness are achieved if research questions meet the FINER criteria. In addition to the FINER criteria, Ratan et al. described focus, complexity, novelty, feasibility, and measurability for evaluating the effectiveness of research questions. 14

The PICOT and PEO frameworks are also used when developing research questions. 1 The following elements are addressed in these frameworks, PICOT: P-population/patients/problem, I-intervention or indicator being studied, C-comparison group, O-outcome of interest, and T-timeframe of the study; PEO: P-population being studied, E-exposure to preexisting conditions, and O-outcome of interest. 1 Research questions are also considered good if these meet the “FINERMAPS” framework: Feasible, Interesting, Novel, Ethical, Relevant, Manageable, Appropriate, Potential value/publishable, and Systematic. 14

As we indicated earlier, research questions and hypotheses that are not carefully formulated result in unethical studies or poor outcomes. To illustrate this, we provide some examples of ambiguous research question and hypotheses that result in unclear and weak research objectives in quantitative research ( Table 6 ) 16 and qualitative research ( Table 7 ) 17 , and how to transform these ambiguous research question(s) and hypothesis(es) into clear and good statements.

CONSTRUCTING RESEARCH QUESTIONS AND HYPOTHESES

To construct effective research questions and hypotheses, it is very important to 1) clarify the background and 2) identify the research problem at the outset of the research, within a specific timeframe. 9 Then, 3) review or conduct preliminary research to collect all available knowledge about the possible research questions by studying theories and previous studies. 18 Afterwards, 4) construct research questions to investigate the research problem. Identify variables to be accessed from the research questions 4 and make operational definitions of constructs from the research problem and questions. Thereafter, 5) construct specific deductive or inductive predictions in the form of hypotheses. 4 Finally, 6) state the study aims . This general flow for constructing effective research questions and hypotheses prior to conducting research is shown in Fig. 1 .

Research questions are used more frequently in qualitative research than objectives or hypotheses. 3 These questions seek to discover, understand, explore or describe experiences by asking “What” or “How.” The questions are open-ended to elicit a description rather than to relate variables or compare groups. The questions are continually reviewed, reformulated, and changed during the qualitative study. 3 Research questions are also used more frequently in survey projects than hypotheses in experiments in quantitative research to compare variables and their relationships.

Hypotheses are constructed based on the variables identified and as an if-then statement, following the template, ‘If a specific action is taken, then a certain outcome is expected.’ At this stage, some ideas regarding expectations from the research to be conducted must be drawn. 18 Then, the variables to be manipulated (independent) and influenced (dependent) are defined. 4 Thereafter, the hypothesis is stated and refined, and reproducible data tailored to the hypothesis are identified, collected, and analyzed. 4 The hypotheses must be testable and specific, 18 and should describe the variables and their relationships, the specific group being studied, and the predicted research outcome. 18 Hypotheses construction involves a testable proposition to be deduced from theory, and independent and dependent variables to be separated and measured separately. 3 Therefore, good hypotheses must be based on good research questions constructed at the start of a study or trial. 12

In summary, research questions are constructed after establishing the background of the study. Hypotheses are then developed based on the research questions. Thus, it is crucial to have excellent research questions to generate superior hypotheses. In turn, these would determine the research objectives and the design of the study, and ultimately, the outcome of the research. 12 Algorithms for building research questions and hypotheses are shown in Fig. 2 for quantitative research and in Fig. 3 for qualitative research.

EXAMPLES OF RESEARCH QUESTIONS FROM PUBLISHED ARTICLES

  • EXAMPLE 1. Descriptive research question (quantitative research)
  • - Presents research variables to be assessed (distinct phenotypes and subphenotypes)
  • “BACKGROUND: Since COVID-19 was identified, its clinical and biological heterogeneity has been recognized. Identifying COVID-19 phenotypes might help guide basic, clinical, and translational research efforts.
  • RESEARCH QUESTION: Does the clinical spectrum of patients with COVID-19 contain distinct phenotypes and subphenotypes? ” 19
  • EXAMPLE 2. Relationship research question (quantitative research)
  • - Shows interactions between dependent variable (static postural control) and independent variable (peripheral visual field loss)
  • “Background: Integration of visual, vestibular, and proprioceptive sensations contributes to postural control. People with peripheral visual field loss have serious postural instability. However, the directional specificity of postural stability and sensory reweighting caused by gradual peripheral visual field loss remain unclear.
  • Research question: What are the effects of peripheral visual field loss on static postural control ?” 20
  • EXAMPLE 3. Comparative research question (quantitative research)
  • - Clarifies the difference among groups with an outcome variable (patients enrolled in COMPERA with moderate PH or severe PH in COPD) and another group without the outcome variable (patients with idiopathic pulmonary arterial hypertension (IPAH))
  • “BACKGROUND: Pulmonary hypertension (PH) in COPD is a poorly investigated clinical condition.
  • RESEARCH QUESTION: Which factors determine the outcome of PH in COPD?
  • STUDY DESIGN AND METHODS: We analyzed the characteristics and outcome of patients enrolled in the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) with moderate or severe PH in COPD as defined during the 6th PH World Symposium who received medical therapy for PH and compared them with patients with idiopathic pulmonary arterial hypertension (IPAH) .” 21
  • EXAMPLE 4. Exploratory research question (qualitative research)
  • - Explores areas that have not been fully investigated (perspectives of families and children who receive care in clinic-based child obesity treatment) to have a deeper understanding of the research problem
  • “Problem: Interventions for children with obesity lead to only modest improvements in BMI and long-term outcomes, and data are limited on the perspectives of families of children with obesity in clinic-based treatment. This scoping review seeks to answer the question: What is known about the perspectives of families and children who receive care in clinic-based child obesity treatment? This review aims to explore the scope of perspectives reported by families of children with obesity who have received individualized outpatient clinic-based obesity treatment.” 22
  • EXAMPLE 5. Relationship research question (quantitative research)
  • - Defines interactions between dependent variable (use of ankle strategies) and independent variable (changes in muscle tone)
  • “Background: To maintain an upright standing posture against external disturbances, the human body mainly employs two types of postural control strategies: “ankle strategy” and “hip strategy.” While it has been reported that the magnitude of the disturbance alters the use of postural control strategies, it has not been elucidated how the level of muscle tone, one of the crucial parameters of bodily function, determines the use of each strategy. We have previously confirmed using forward dynamics simulations of human musculoskeletal models that an increased muscle tone promotes the use of ankle strategies. The objective of the present study was to experimentally evaluate a hypothesis: an increased muscle tone promotes the use of ankle strategies. Research question: Do changes in the muscle tone affect the use of ankle strategies ?” 23

EXAMPLES OF HYPOTHESES IN PUBLISHED ARTICLES

  • EXAMPLE 1. Working hypothesis (quantitative research)
  • - A hypothesis that is initially accepted for further research to produce a feasible theory
  • “As fever may have benefit in shortening the duration of viral illness, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response when taken during the early stages of COVID-19 illness .” 24
  • “In conclusion, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response . The difference in perceived safety of these agents in COVID-19 illness could be related to the more potent efficacy to reduce fever with ibuprofen compared to acetaminophen. Compelling data on the benefit of fever warrant further research and review to determine when to treat or withhold ibuprofen for early stage fever for COVID-19 and other related viral illnesses .” 24
  • EXAMPLE 2. Exploratory hypothesis (qualitative research)
  • - Explores particular areas deeper to clarify subjective experience and develop a formal hypothesis potentially testable in a future quantitative approach
  • “We hypothesized that when thinking about a past experience of help-seeking, a self distancing prompt would cause increased help-seeking intentions and more favorable help-seeking outcome expectations .” 25
  • “Conclusion
  • Although a priori hypotheses were not supported, further research is warranted as results indicate the potential for using self-distancing approaches to increasing help-seeking among some people with depressive symptomatology.” 25
  • EXAMPLE 3. Hypothesis-generating research to establish a framework for hypothesis testing (qualitative research)
  • “We hypothesize that compassionate care is beneficial for patients (better outcomes), healthcare systems and payers (lower costs), and healthcare providers (lower burnout). ” 26
  • Compassionomics is the branch of knowledge and scientific study of the effects of compassionate healthcare. Our main hypotheses are that compassionate healthcare is beneficial for (1) patients, by improving clinical outcomes, (2) healthcare systems and payers, by supporting financial sustainability, and (3) HCPs, by lowering burnout and promoting resilience and well-being. The purpose of this paper is to establish a scientific framework for testing the hypotheses above . If these hypotheses are confirmed through rigorous research, compassionomics will belong in the science of evidence-based medicine, with major implications for all healthcare domains.” 26
  • EXAMPLE 4. Statistical hypothesis (quantitative research)
  • - An assumption is made about the relationship among several population characteristics ( gender differences in sociodemographic and clinical characteristics of adults with ADHD ). Validity is tested by statistical experiment or analysis ( chi-square test, Students t-test, and logistic regression analysis)
  • “Our research investigated gender differences in sociodemographic and clinical characteristics of adults with ADHD in a Japanese clinical sample. Due to unique Japanese cultural ideals and expectations of women's behavior that are in opposition to ADHD symptoms, we hypothesized that women with ADHD experience more difficulties and present more dysfunctions than men . We tested the following hypotheses: first, women with ADHD have more comorbidities than men with ADHD; second, women with ADHD experience more social hardships than men, such as having less full-time employment and being more likely to be divorced.” 27
  • “Statistical Analysis
  • ( text omitted ) Between-gender comparisons were made using the chi-squared test for categorical variables and Students t-test for continuous variables…( text omitted ). A logistic regression analysis was performed for employment status, marital status, and comorbidity to evaluate the independent effects of gender on these dependent variables.” 27

EXAMPLES OF HYPOTHESIS AS WRITTEN IN PUBLISHED ARTICLES IN RELATION TO OTHER PARTS

  • EXAMPLE 1. Background, hypotheses, and aims are provided
  • “Pregnant women need skilled care during pregnancy and childbirth, but that skilled care is often delayed in some countries …( text omitted ). The focused antenatal care (FANC) model of WHO recommends that nurses provide information or counseling to all pregnant women …( text omitted ). Job aids are visual support materials that provide the right kind of information using graphics and words in a simple and yet effective manner. When nurses are not highly trained or have many work details to attend to, these job aids can serve as a content reminder for the nurses and can be used for educating their patients (Jennings, Yebadokpo, Affo, & Agbogbe, 2010) ( text omitted ). Importantly, additional evidence is needed to confirm how job aids can further improve the quality of ANC counseling by health workers in maternal care …( text omitted )” 28
  • “ This has led us to hypothesize that the quality of ANC counseling would be better if supported by job aids. Consequently, a better quality of ANC counseling is expected to produce higher levels of awareness concerning the danger signs of pregnancy and a more favorable impression of the caring behavior of nurses .” 28
  • “This study aimed to examine the differences in the responses of pregnant women to a job aid-supported intervention during ANC visit in terms of 1) their understanding of the danger signs of pregnancy and 2) their impression of the caring behaviors of nurses to pregnant women in rural Tanzania.” 28
  • EXAMPLE 2. Background, hypotheses, and aims are provided
  • “We conducted a two-arm randomized controlled trial (RCT) to evaluate and compare changes in salivary cortisol and oxytocin levels of first-time pregnant women between experimental and control groups. The women in the experimental group touched and held an infant for 30 min (experimental intervention protocol), whereas those in the control group watched a DVD movie of an infant (control intervention protocol). The primary outcome was salivary cortisol level and the secondary outcome was salivary oxytocin level.” 29
  • “ We hypothesize that at 30 min after touching and holding an infant, the salivary cortisol level will significantly decrease and the salivary oxytocin level will increase in the experimental group compared with the control group .” 29
  • EXAMPLE 3. Background, aim, and hypothesis are provided
  • “In countries where the maternal mortality ratio remains high, antenatal education to increase Birth Preparedness and Complication Readiness (BPCR) is considered one of the top priorities [1]. BPCR includes birth plans during the antenatal period, such as the birthplace, birth attendant, transportation, health facility for complications, expenses, and birth materials, as well as family coordination to achieve such birth plans. In Tanzania, although increasing, only about half of all pregnant women attend an antenatal clinic more than four times [4]. Moreover, the information provided during antenatal care (ANC) is insufficient. In the resource-poor settings, antenatal group education is a potential approach because of the limited time for individual counseling at antenatal clinics.” 30
  • “This study aimed to evaluate an antenatal group education program among pregnant women and their families with respect to birth-preparedness and maternal and infant outcomes in rural villages of Tanzania.” 30
  • “ The study hypothesis was if Tanzanian pregnant women and their families received a family-oriented antenatal group education, they would (1) have a higher level of BPCR, (2) attend antenatal clinic four or more times, (3) give birth in a health facility, (4) have less complications of women at birth, and (5) have less complications and deaths of infants than those who did not receive the education .” 30

Research questions and hypotheses are crucial components to any type of research, whether quantitative or qualitative. These questions should be developed at the very beginning of the study. Excellent research questions lead to superior hypotheses, which, like a compass, set the direction of research, and can often determine the successful conduct of the study. Many research studies have floundered because the development of research questions and subsequent hypotheses was not given the thought and meticulous attention needed. The development of research questions and hypotheses is an iterative process based on extensive knowledge of the literature and insightful grasp of the knowledge gap. Focused, concise, and specific research questions provide a strong foundation for constructing hypotheses which serve as formal predictions about the research outcomes. Research questions and hypotheses are crucial elements of research that should not be overlooked. They should be carefully thought of and constructed when planning research. This avoids unethical studies and poor outcomes by defining well-founded objectives that determine the design, course, and outcome of the study.

FAQ: Research Design & Method

What is the difference between Research Design and Research Method?

Research design is a plan to answer your research question.  A research method is a strategy used to implement that plan.  Research design and methods are different but closely related, because good research design ensures that the data you obtain will help you answer your research question more effectively.

Which research method should I choose ?

It depends on your research goal.  It depends on what subjects (and who) you want to study.  Let's say you are interested in studying what makes people happy, or why some students are more conscious about recycling on campus.  To answer these questions, you need to make a decision about how to collect your data.  Most frequently used methods include:

  • Observation / Participant Observation
  • Focus Groups
  • Experiments
  • Secondary Data Analysis / Archival Study
  • Mixed Methods (combination of some of the above)

One particular method could be better suited to your research goal than others, because the data you collect from different methods will be different in quality and quantity.   For instance, surveys are usually designed to produce relatively short answers, rather than the extensive responses expected in qualitative interviews.

What other factors should I consider when choosing one method over another?

Time for data collection and analysis is something you want to consider.  An observation or interview method, so-called qualitative approach, helps you collect richer information, but it takes time.  Using a survey helps you collect more data quickly, yet it may lack details.  So, you will need to consider the time you have for research and the balance between strengths and weaknesses associated with each method (e.g., qualitative vs. quantitative).

Types of quantitative research designs

Quantitative research design uses a variety of empirical methods to assess a phenomenon. The most common method is the experiment, but there are other types of quantitative research as well, such as correlation studies and case studies.

In contrast with qualitative research, which relies on subjective interpretations and extensive explorations, the various types of quantitative methods use objective analysis to reveal patterns and relations among data points that often have a numerical value. Quantitative research provides a mathematical summary of the results.

Let’s look at quantitative research design, the types of quantitative research methods and their respective strengths and weaknesses.

Types Of Quantitative Research

Components of quantitative research design.

If a researcher is studying a single variable, time, space, or another construct, they’re engaged in qualitative research. However, if that variable is a collection of quantitative data points—such as the number of employees that use a workplace break room compared to the number of employees who use other break rooms—the researcher is engaged in quantitative research.

Here are some methods commonly used in quantitative research design:

1. Experiment

The experiment is perhaps the most common way for quantitative researchers to gather data. In this method, researchers manipulate one variable at a time, while they hold all other variables constant. If a researcher wishes to determine which type of computer mouse is easier for employees to use, they must ensure the employees are experienced with computers, comfortable with their chairs or desks and have no issues with their eyesight. Common methods for this type of research include randomized experiments, non-randomized experiments, clinical trials and field studies.

2. Correlation

Correlation studies come in many forms, from simple correlation diagrams to the analysis of multiple variables. For instance, a researcher examining rates of depression among veterinarians could look at associations between self-perceived social status, salary and depression.

3. Cohort Studies

Cohort studies provide a way to measure the extent of change over a period of time. This type of research can lead to results that are both objective and subjective, depending on the type of study employed. For instance, a cohort study examining police officer salaries could determine what salary a police officer should make in an area. However, this same study could also delve into the subjective question of whether police officers are fairly paid compared to other professions.

Research design is a critical factor in the success of a study.

While there are many types of quantitative research methods that can be employed, the basic parts of all research designs are the same. Here are the principal components:

At the heart of every research project is a well-framed and considered question. Having a clear objective is the most important part of quantitative research design. Some examples of research questions could be:

  • Which type of coffee brewing method extracts the most flavor?
  • Which books are contributing most to a publisher’s profit?
  • Which newspaper is the most widely read in a city?

In quantitative research design, researchers may explore the relationship between variables in a correlation study, or it could mean determining what variables are best in an experiment.

Once the aim is in place, the actual data collection method must be chosen. This will depend on the data needed to answer the research question. Some options are:

  • Participant observations
  • Experimental data

As long as the data is expressed numerically, it is quantitative data.

The selection process used to choose participants is a critical component of all types of quantitative research designs. Researchers need a well-defined population. This group can be as small as two people, but it could also be thousands of people as well.

Data Analysis

Once the data is collated, a researcher must decide how to analyze it. Some options at their disposal include:

  • Descriptive analysis
  • Content analysis
  • Statistical tests

Once again, it depends on the research question and the goals of the study.

Presentation

This is sometimes referred to as dissemination. How will the research findings be shared with the world? Common choices are:

  • Presentations
  • Website articles and blogs

A quantitative researcher’s greatest contribution is that their work can be replicated. Because quantitative research relies on numbers, the results of the study can be exactly duplicated by other researchers.

With Harappa’s Thinking Critically course, professionals at all levels of their careers will learn how to organize their thoughts with the most impact. Assessing available information is an important part of this. Making gut decisions isn’t the mark of a mature manager—when decisions need to be made, all data must be considered dispassionately. These insights then need to be shared with team members and bosses. Give your teams the best chance of success with this course that delivers transformative skills.

Quantitative Research: What It Is, Practices & Methods

Quantitative research

Quantitative research involves analyzing and gathering numerical data to uncover trends, calculate averages, evaluate relationships, and derive overarching insights. It’s used in various fields, including the natural and social sciences. Quantitative data analysis employs statistical techniques for processing and interpreting numeric data.

Research designs in the quantitative realm outline how data will be collected and analyzed with methods like experiments and surveys. Qualitative methods complement quantitative research by focusing on non-numerical data, adding depth to understanding. Data collection methods can be qualitative or quantitative, depending on research goals. Researchers often use a combination of both approaches to gain a comprehensive understanding of phenomena.

What is Quantitative Research?

Quantitative research is a systematic investigation of phenomena by gathering quantifiable data and performing statistical, mathematical, or computational techniques. Quantitative research collects statistically significant information from existing and potential customers using sampling methods and sending out online surveys , online polls , and questionnaires , for example.

One of the main characteristics of this type of research is that the results can be depicted in numerical form. After carefully collecting structured observations and understanding these numbers, it’s possible to predict the future of a product or service, establish causal relationships or Causal Research , and make changes accordingly. Quantitative research primarily centers on the analysis of numerical data and utilizes inferential statistics to derive conclusions that can be extrapolated to the broader population.

An example of a quantitative research study is the survey conducted to understand how long a doctor takes to tend to a patient when the patient walks into the hospital. A patient satisfaction survey can be administered to ask questions like how long a doctor takes to see a patient, how often a patient walks into a hospital, and other such questions, which are dependent variables in the research. This kind of research method is often employed in the social sciences, and it involves using mathematical frameworks and theories to effectively present data, ensuring that the results are logical, statistically sound, and unbiased.

Data collection in quantitative research uses a structured method and is typically conducted on larger samples representing the entire population. Researchers use quantitative methods to collect numerical data, which is then subjected to statistical analysis to determine statistically significant findings. This approach is valuable in both experimental research and social research, as it helps in making informed decisions and drawing reliable conclusions based on quantitative data.

Quantitative Research Characteristics

Quantitative research has several unique characteristics that make it well-suited for specific projects. Let’s explore the most crucial of these characteristics so that you can consider them when planning your next research project:

quantitative research design and methods

  • Structured tools: Quantitative research relies on structured tools such as surveys, polls, or questionnaires to gather quantitative data . Using such structured methods helps collect in-depth and actionable numerical data from the survey respondents, making it easier to perform data analysis.
  • Sample size: Quantitative research is conducted on a significant sample size  representing the target market . Appropriate Survey Sampling methods, a fundamental aspect of quantitative research methods, must be employed when deriving the sample to fortify the research objective and ensure the reliability of the results.
  • Close-ended questions: Closed-ended questions , specifically designed to align with the research objectives, are a cornerstone of quantitative research. These questions facilitate the collection of quantitative data and are extensively used in data collection processes.
  • Prior studies: Before collecting feedback from respondents, researchers often delve into previous studies related to the research topic. This preliminary research helps frame the study effectively and ensures the data collection process is well-informed.
  • Quantitative data: Typically, quantitative data is represented using tables, charts, graphs, or other numerical forms. This visual representation aids in understanding the collected data and is essential for rigorous data analysis, a key component of quantitative research methods.
  • Generalization of results: One of the strengths of quantitative research is its ability to generalize results to the entire population. It means that the findings derived from a sample can be extrapolated to make informed decisions and take appropriate actions for improvement based on numerical data analysis.

Quantitative Research Methods

Quantitative research methods are systematic approaches used to gather and analyze numerical data to understand and draw conclusions about a phenomenon or population. Here are the quantitative research methods:

  • Primary quantitative research methods
  • Secondary quantitative research methods

Primary Quantitative Research Methods

Primary quantitative research is the most widely used method of conducting market research. The distinct feature of primary research is that the researcher focuses on collecting data directly rather than depending on data collected from previously done research. Primary quantitative research design can be broken down into three further distinctive tracks and the process flow. They are:

A. Techniques and Types of Studies

There are multiple types of primary quantitative research. They can be distinguished into the four following distinctive methods, which are:

01. Survey Research

Survey Research is fundamental for all quantitative outcome research methodologies and studies. Surveys are used to ask questions to a sample of respondents, using various types such as online polls, online surveys, paper questionnaires, web-intercept surveys , etc. Every small and big organization intends to understand what their customers think about their products and services, how well new features are faring in the market, and other such details.

By conducting survey research, an organization can ask multiple survey questions , collect data from a pool of customers, and analyze this collected data to produce numerical results. It is the first step towards collecting data for any research. You can use single ease questions . A single-ease question is a straightforward query that elicits a concise and uncomplicated response.

This type of research can be conducted with a specific target audience group and also can be conducted across multiple groups along with comparative analysis . A prerequisite for this type of research is that the sample of respondents must have randomly selected members. This way, a researcher can easily maintain the accuracy of the obtained results as a huge variety of respondents will be addressed using random selection. 

Traditionally, survey research was conducted face-to-face or via phone calls. Still, with the progress made by online mediums such as email or social media, survey research has also spread to online mediums.There are two types of surveys , either of which can be chosen based on the time in hand and the kind of data required:

Cross-sectional surveys: Cross-sectional surveys are observational surveys conducted in situations where the researcher intends to collect data from a sample of the target population at a given point in time. Researchers can evaluate various variables at a particular time. Data gathered using this type of survey is from people who depict similarity in all variables except the variables which are considered for research . Throughout the survey, this one variable will stay constant.

  • Cross-sectional surveys are popular with retail, SMEs, and healthcare industries. Information is garnered without modifying any parameters in the variable ecosystem.
  • Multiple samples can be analyzed and compared using a cross-sectional survey research method.
  • Multiple variables can be evaluated using this type of survey research.
  • The only disadvantage of cross-sectional surveys is that the cause-effect relationship of variables cannot be established as it usually evaluates variables at a particular time and not across a continuous time frame.

Longitudinal surveys: Longitudinal surveys are also observational surveys , but unlike cross-sectional surveys, longitudinal surveys are conducted across various time durations to observe a change in respondent behavior and thought processes. This time can be days, months, years, or even decades. For instance, a researcher planning to analyze the change in buying habits of teenagers over 5 years will conduct longitudinal surveys.

  • In cross-sectional surveys, the same variables were evaluated at a given time, and in longitudinal surveys, different variables can be analyzed at different intervals.
  • Longitudinal surveys are extensively used in the field of medicine and applied sciences. Apart from these two fields, they are also used to observe a change in the market trend analysis , analyze customer satisfaction, or gain feedback on products/services.
  • In situations where the sequence of events is highly essential, longitudinal surveys are used.
  • Researchers say that when research subjects need to be thoroughly inspected before concluding, they rely on longitudinal surveys.

02. Correlational Research

A comparison between two entities is invariable. Correlation research is conducted to establish a relationship between two closely-knit entities and how one impacts the other, and what changes are eventually observed. This research method is carried out to give value to naturally occurring relationships, and a minimum of two different groups are required to conduct this quantitative research method successfully. Without assuming various aspects, a relationship between two groups or entities must be established.

Researchers use this quantitative research design to correlate two or more variables using mathematical analysis methods. Patterns, relationships, and trends between variables are concluded as they exist in their original setup. The impact of one of these variables on the other is observed, along with how it changes the relationship between the two variables. Researchers tend to manipulate one of the variables to attain the desired results.

Ideally, it is advised not to make conclusions merely based on correlational research. This is because it is not mandatory that if two variables are in sync that they are interrelated.

Example of Correlational Research Questions :

  • The relationship between stress and depression.
  • The equation between fame and money.
  • The relation between activities in a third-grade class and its students.

03. Causal-comparative Research

This research method mainly depends on the factor of comparison. Also called quasi-experimental research , this quantitative research method is used by researchers to conclude the cause-effect equation between two or more variables, where one variable is dependent on the other independent variable. The independent variable is established but not manipulated, and its impact on the dependent variable is observed. These variables or groups must be formed as they exist in the natural setup. As the dependent and independent variables will always exist in a group, it is advised that the conclusions are carefully established by keeping all the factors in mind.

Causal-comparative research is not restricted to the statistical analysis of two variables but extends to analyzing how various variables or groups change under the influence of the same changes. This research is conducted irrespective of the type of relationship that exists between two or more variables. Statistical analysis plan is used to present the outcome using this quantitative research method.

Example of Causal-Comparative Research Questions:

  • The impact of drugs on a teenager. The effect of good education on a freshman. The effect of substantial food provision in the villages of Africa.

04. Experimental Research

Also known as true experimentation, this research method relies on a theory. As the name suggests, experimental research is usually based on one or more theories. This theory has yet to be proven before and is merely a supposition. In experimental research, an analysis is done around proving or disproving the statement. This research method is used in natural sciences. Traditional research methods are more effective than modern techniques.

There can be multiple theories in experimental research. A theory is a statement that can be verified or refuted.

After establishing the statement, efforts are made to understand whether it is valid or invalid. This quantitative research method is mainly used in natural or social sciences as various statements must be proved right or wrong.

  • Traditional research methods are more effective than modern techniques.
  • Systematic teaching schedules help children who struggle to cope with the course.
  • It is a boon to have responsible nursing staff for ailing parents.

B. Data Collection Methodologies

The second major step in primary quantitative research is data collection. Data collection can be divided into sampling methods and data collection using surveys and polls.

01. Data Collection Methodologies: Sampling Methods

There are two main sampling methods for quantitative research: Probability and Non-probability sampling .

Probability sampling: A theory of probability is used to filter individuals from a population and create samples in probability sampling . Participants of a sample are chosen by random selection processes. Each target audience member has an equal opportunity to be selected in the sample.

There are four main types of probability sampling:

  • Simple random sampling: As the name indicates, simple random sampling is nothing but a random selection of elements for a sample. This sampling technique is implemented where the target population is considerably large.
  • Stratified random sampling: In the stratified random sampling method , a large population is divided into groups (strata), and members of a sample are chosen randomly from these strata. The various segregated strata should ideally not overlap one another.
  • Cluster sampling: Cluster sampling is a probability sampling method using which the main segment is divided into clusters, usually using geographic segmentation and demographic segmentation parameters.
  • Systematic sampling: Systematic sampling is a technique where the starting point of the sample is chosen randomly, and all the other elements are chosen using a fixed interval. This interval is calculated by dividing the population size by the target sample size.

Non-probability sampling: Non-probability sampling is where the researcher’s knowledge and experience are used to create samples. Because of the researcher’s involvement, not all the target population members have an equal probability of being selected to be a part of a sample.

There are five non-probability sampling models:

  • Convenience sampling: In convenience sampling , elements of a sample are chosen only due to one prime reason: their proximity to the researcher. These samples are quick and easy to implement as there is no other parameter of selection involved.
  • Consecutive sampling: Consecutive sampling is quite similar to convenience sampling, except for the fact that researchers can choose a single element or a group of samples and conduct research consecutively over a significant period and then perform the same process with other samples.
  • Quota sampling: Using quota sampling , researchers can select elements using their knowledge of target traits and personalities to form strata. Members of various strata can then be chosen to be a part of the sample as per the researcher’s understanding.
  • Snowball sampling: Snowball sampling is conducted with target audiences who are difficult to contact and get information. It is popular in cases where the target audience for analysis research is rare to put together.
  • Judgmental sampling: Judgmental sampling is a non-probability sampling method where samples are created only based on the researcher’s experience and research skill .

02. Data collection methodologies: Using surveys & polls

Once the sample is determined, then either surveys or polls can be distributed to collect the data for quantitative research.

Using surveys for primary quantitative research

A survey is defined as a research method used for collecting data from a pre-defined group of respondents to gain information and insights on various topics of interest. The ease of survey distribution and the wide number of people it can reach depending on the research time and objective makes it one of the most important aspects of conducting quantitative research.

Fundamental levels of measurement – nominal, ordinal, interval, and ratio scales

Four measurement scales are fundamental to creating a multiple-choice question in a survey. They are nominal, ordinal, interval, and ratio measurement scales without the fundamentals of which no multiple-choice questions can be created. Hence, it is crucial to understand these measurement levels to develop a robust survey.

Use of different question types

To conduct quantitative research, close-ended questions must be used in a survey. They can be a mix of multiple question types, including multiple-choice questions like semantic differential scale questions , rating scale questions , etc.

Survey Distribution and Survey Data Collection

In the above, we have seen the process of building a survey along with the research design to conduct primary quantitative research. Survey distribution to collect data is the other important aspect of the survey process. There are different ways of survey distribution. Some of the most commonly used methods are:

  • Email: Sending a survey via email is the most widely used and effective survey distribution method. This method’s response rate is high because the respondents know your brand. You can use the QuestionPro email management feature to send out and collect survey responses.
  • Buy respondents: Another effective way to distribute a survey and conduct primary quantitative research is to use a sample. Since the respondents are knowledgeable and are on the panel by their own will, responses are much higher.
  • Embed survey on a website: Embedding a survey on a website increases a high number of responses as the respondent is already in close proximity to the brand when the survey pops up.
  • Social distribution: Using social media to distribute the survey aids in collecting a higher number of responses from the people that are aware of the brand.
  • QR code: QuestionPro QR codes store the URL for the survey. You can print/publish this code in magazines, signs, business cards, or on just about any object/medium.
  • SMS survey: The SMS survey is a quick and time-effective way to collect a high number of responses.
  • Offline Survey App: The QuestionPro App allows users to circulate surveys quickly, and the responses can be collected both online and offline.

Survey example

An example of a survey is a short customer satisfaction (CSAT) survey that can quickly be built and deployed to collect feedback about what the customer thinks about a brand and how satisfied and referenceable the brand is.

Using polls for primary quantitative research

Polls are a method to collect feedback using close-ended questions from a sample. The most commonly used types of polls are election polls and exit polls . Both of these are used to collect data from a large sample size but using basic question types like multiple-choice questions.

C. Data Analysis Techniques

The third aspect of primary quantitative research design is data analysis . After collecting raw data, there must be an analysis of this data to derive statistical inferences from this research. It is important to relate the results to the research objective and establish the statistical relevance of the results.

Remember to consider aspects of research that were not considered for the data collection process and report the difference between what was planned vs. what was actually executed.

It is then required to select precise Statistical Analysis Methods , such as SWOT, Conjoint, Cross-tabulation, etc., to analyze the quantitative data.

  • SWOT analysis: SWOT Analysis stands for the acronym of Strengths, Weaknesses, Opportunities, and Threat analysis. Organizations use this statistical analysis technique to evaluate their performance internally and externally to develop effective strategies for improvement.
  • Conjoint Analysis: Conjoint Analysis is a market analysis method to learn how individuals make complicated purchasing decisions. Trade-offs are involved in an individual’s daily activities, and these reflect their ability to decide from a complex list of product/service options.
  • Cross-tabulation: Cross-tabulation is one of the preliminary statistical market analysis methods which establishes relationships, patterns, and trends within the various parameters of the research study.
  • TURF Analysis: TURF Analysis , an acronym for Totally Unduplicated Reach and Frequency Analysis, is executed in situations where the reach of a favorable communication source is to be analyzed along with the frequency of this communication. It is used for understanding the potential of a target market.

Inferential statistics methods such as confidence interval, the margin of error, etc., can then be used to provide results.

Secondary Quantitative Research Methods

Secondary quantitative research or desk research is a research method that involves using already existing data or secondary data. Existing data is summarized and collated to increase the overall effectiveness of the research.

This research method involves collecting quantitative data from existing data sources like the internet, government resources, libraries, research reports, etc. Secondary quantitative research helps to validate the data collected from primary quantitative research and aid in strengthening or proving, or disproving previously collected data.

The following are five popularly used secondary quantitative research methods:

  • Data available on the internet: With the high penetration of the internet and mobile devices, it has become increasingly easy to conduct quantitative research using the internet. Information about most research topics is available online, and this aids in boosting the validity of primary quantitative data.
  • Government and non-government sources: Secondary quantitative research can also be conducted with the help of government and non-government sources that deal with market research reports. This data is highly reliable and in-depth and hence, can be used to increase the validity of quantitative research design.
  • Public libraries: Now a sparingly used method of conducting quantitative research, it is still a reliable source of information, though. Public libraries have copies of important research that was conducted earlier. They are a storehouse of valuable information and documents from which information can be extracted.
  • Educational institutions: Educational institutions conduct in-depth research on multiple topics, and hence, the reports that they publish are an important source of validation in quantitative research.
  • Commercial information sources: Local newspapers, journals, magazines, radio, and TV stations are great sources to obtain data for secondary quantitative research. These commercial information sources have in-depth, first-hand information on market research, demographic segmentation, and similar subjects.

Quantitative Research Examples

Some examples of quantitative research are:

  • A customer satisfaction template can be used if any organization would like to conduct a customer satisfaction (CSAT) survey . Through this kind of survey, an organization can collect quantitative data and metrics on the goodwill of the brand or organization in the customer’s mind based on multiple parameters such as product quality, pricing, customer experience, etc. This data can be collected by asking a net promoter score (NPS) question , matrix table questions, etc. that provide data in the form of numbers that can be analyzed and worked upon.
  • Another example of quantitative research is an organization that conducts an event, collecting feedback from attendees about the value they see from the event. By using an event survey , the organization can collect actionable feedback about the satisfaction levels of customers during various phases of the event such as the sales, pre and post-event, the likelihood of recommending the organization to their friends and colleagues, hotel preferences for the future events and other such questions.

What are the Advantages of Quantitative Research?

There are many advantages to quantitative research. Some of the major advantages of why researchers use this method in market research are:

Collect Reliable and Accurate Data:

Quantitative research is a powerful method for collecting reliable and accurate quantitative data. Since data is collected, analyzed, and presented in numbers, the results obtained are incredibly reliable and objective. Numbers do not lie and offer an honest and precise picture of the conducted research without discrepancies. In situations where a researcher aims to eliminate bias and predict potential conflicts, quantitative research is the method of choice.

Quick Data Collection:

Quantitative research involves studying a group of people representing a larger population. Researchers use a survey or another quantitative research method to efficiently gather information from these participants, making the process of analyzing the data and identifying patterns faster and more manageable through the use of statistical analysis. This advantage makes quantitative research an attractive option for projects with time constraints.

Wider Scope of Data Analysis:

Quantitative research, thanks to its utilization of statistical methods, offers an extensive range of data collection and analysis. Researchers can delve into a broader spectrum of variables and relationships within the data, enabling a more thorough comprehension of the subject under investigation. This expanded scope is precious when dealing with complex research questions that require in-depth numerical analysis.

Eliminate Bias:

One of the significant advantages of quantitative research is its ability to eliminate bias. This research method leaves no room for personal comments or the biasing of results, as the findings are presented in numerical form. This objectivity makes the results fair and reliable in most cases, reducing the potential for researcher bias or subjectivity.

In summary, quantitative research involves collecting, analyzing, and presenting quantitative data using statistical analysis. It offers numerous advantages, including the collection of reliable and accurate data, quick data collection, a broader scope of data analysis, and the elimination of bias, making it a valuable approach in the field of research. When considering the benefits of quantitative research, it’s essential to recognize its strengths in contrast to qualitative methods and its role in collecting and analyzing numerical data for a more comprehensive understanding of research topics.

Best Practices to Conduct Quantitative Research

Here are some best practices for conducting quantitative research:

Tips to conduct quantitative research

  • Differentiate between quantitative and qualitative: Understand the difference between the two methodologies and apply the one that suits your needs best.
  • Choose a suitable sample size: Ensure that you have a sample representative of your population and large enough to be statistically weighty.
  • Keep your research goals clear and concise: Know your research goals before you begin data collection to ensure you collect the right amount and the right quantity of data.
  • Keep the questions simple: Remember that you will be reaching out to a demographically wide audience. Pose simple questions for your respondents to understand easily.

Quantitative Research vs Qualitative Research

Quantitative research and qualitative research are two distinct approaches to conducting research, each with its own set of methods and objectives. Here’s a comparison of the two:

quantitative research design and methods

Quantitative Research

  • Objective: The primary goal of quantitative research is to quantify and measure phenomena by collecting numerical data. It aims to test hypotheses, establish patterns, and generalize findings to a larger population.
  • Data Collection: Quantitative research employs systematic and standardized approaches for data collection, including techniques like surveys, experiments, and observations that involve predefined variables. It is often collected from a large and representative sample.
  • Data Analysis: Data is analyzed using statistical techniques, such as descriptive statistics, inferential statistics, and mathematical modeling. Researchers use statistical tests to draw conclusions and make generalizations based on numerical data.
  • Sample Size: Quantitative research often involves larger sample sizes to ensure statistical significance and generalizability.
  • Results: The results are typically presented in tables, charts, and statistical summaries, making them highly structured and objective.
  • Generalizability: Researchers intentionally structure quantitative research to generate outcomes that can be helpful to a larger population, and they frequently seek to establish causative connections.
  • Emphasis on Objectivity: Researchers aim to minimize bias and subjectivity, focusing on replicable and objective findings.

Qualitative Research

  • Objective: Qualitative research seeks to gain a deeper understanding of the underlying motivations, behaviors, and experiences of individuals or groups. It explores the context and meaning of phenomena.
  • Data Collection: Qualitative research employs adaptable and open-ended techniques for data collection, including methods like interviews, focus groups, observations, and content analysis. It allows participants to express their perspectives in their own words.
  • Data Analysis: Data is analyzed through thematic analysis, content analysis, or grounded theory. Researchers focus on identifying patterns, themes, and insights in the data.
  • Sample Size: Qualitative research typically involves smaller sample sizes due to the in-depth nature of data collection and analysis.
  • Results: Findings are presented in narrative form, often in the participants’ own words. Results are subjective, context-dependent, and provide rich, detailed descriptions.
  • Generalizability: Qualitative research does not aim for broad generalizability but focuses on in-depth exploration within a specific context. It provides a detailed understanding of a particular group or situation.
  • Emphasis on Subjectivity: Researchers acknowledge the role of subjectivity and the researcher’s influence on the Research Process . Participant perspectives and experiences are central to the findings.

Researchers choose between quantitative and qualitative research methods based on their research objectives and the nature of the research question. Each approach has its advantages and drawbacks, and the decision between them hinges on the particular research objectives and the data needed to address research inquiries effectively.

Quantitative research is a structured way of collecting and analyzing data from various sources. Its purpose is to quantify the problem and understand its extent, seeking results that someone can project to a larger population.

Companies that use quantitative rather than qualitative research typically aim to measure magnitudes and seek objectively interpreted statistical results. So if you want to obtain quantitative data that helps you define the structured cause-and-effect relationship between the research problem and the factors, you should opt for this type of research.

What is Research Design?

Crafting a well-defined research design is essential for guiding the entire project, ensuring coherence in methodology and analysis, and upholding the validity and reproducibility of outcomes in the complex landscape of research.

Updated on March 8, 2024

What is Research Design?

Diving into any new project necessitates a solid plan, a blueprint for navigating the very complex research process. It requires a framework that illustrates how all the principal components of the project are intended to work together to address your central research questions - the research design .

This research design is crucial not only for guiding your entire project, from methodology to analysis, but also for ensuring the validity and reproducibility of its outcomes. Let’s take a closer look at research design by focusing on some of its benefits and core elements.

Why do researchers need a research design?

By taking a deliberate approach to research design, you ensure your chosen methods realistically match the project’s objectives. For example:

  • If your project seeks to find out how a certain group of people was influenced by a natural disaster, you could use interviews as methods for gathering data. Then, inductive or deductive coding may be used for analysis.
  • On the other hand, if your project asks how drinking water was affected by that same natural disaster, you would conduct an experiment to measure certain variables. Inferential or descriptive statistical analysis might then be used to assess the data.

Attention to robust research design helps the project run smoothly and efficiently by reducing both errors and unnecessary busywork. Good research design possesses these specific characteristics :

  • Neutrality : Stick to only the facts throughout, creating a plan based on relevant research methods and analysis. Use it as an opportunity to identify possible sources of bias.
  • Reliability : Include reliable methods that support the consistent measurement of project variables. Not only does it improve the legitimacy of your conclusions but also improves the possibility of replication.
  • Validity : Apply measurement tools that minimize systematic errors. Show the straightforward connection between your project results and research hypothesis.
  • Generalizability : Verify that research outcomes are applicable to a larger population beyond the sample studied for your project. Employ sensible methods and processes that easily adapt to variations in the population.
  • Flexibility : Consider alternative measures for adjusting to unexpected data or outcomes. Veer away from rigid procedures and requirements and plan for adaptability.

When you make the effort to focus on these characteristics while developing a research design, the process itself weeds out many potential challenges. It illuminates the relationships between the project’s multiple elements and allows for modifications from the start. 

What makes up a research design?

As the overarching strategy for your entire project, the research design outlines the plans, considerations, and feasibility of every facet. To make this task less daunting, divide it into logical sections by asking yourself these questions:

  • What is your general approach for the study?
  • What type of design will you employ?
  • How will you choose the population and sampling methods?
  • Which data collection methods will you use?
  • How will the data be analyzed?

The answers to these questions depend on your research questions and hypothesis. Before starting your research design, make certain that these elements are well thought out, basically solidified, and truly represent your intentions for the project.

When considering the overall approach for your project, decide what kind of data is needed to answer the research questions. Start by asking yourself:

  • Do I want to establish a cause-and-effect relationship, test a hypothesis, or identify patterns in data? If yes, use quantitative methodologies.
  • Or, am I seeking non-numerical textual information, like human beliefs, cultural experiences, or individual behaviors? If so, use qualitative methods.

Quantitative research methods offer a systematic means of investigating complex phenomena by measuring, describing, and testing relationships between variables. On the other hand, the qualitative approach explores subjective experiences and concepts within their natural settings. Here are some key characteristics of both approaches:

Approach : Basis

Quantitative : The research begins with the formulation of specific research questions or hypotheses that can be tested empirically using numerical data.

Qualitative : The exploratory and flexible nature allows researchers to delve deeply into the subject matter and generate insights.

Approach : Data collection

Quantitative : Typically involves collecting numerical data through methods such as surveys, experiments, structured observations, or existing datasets.

Qualitative : To collect detailed, contextually rich information directly from participants, researchers use methods such as interviews, focus groups, participant observation, and document analysis.

Approach : Data analysis

Quantitative : Quantitative data are analyzed using statistical techniques.

Qualitative : Data analysis in qualitative research involves systematic techniques for organizing, coding, and interpreting textual or visual data. 

Approach : Interpretation of findings

Quantitative : Researchers interpret the results of the statistical analysis in relation to the research questions or hypotheses.

Qualitative : By paying close attention to context, qualitative researchers focus on interpreting the meanings, patterns, and themes that emerge from the data. 

Approach : Reporting results

Quantitative : Reported in a structured format, often including tables, charts, and graphs to present the data visually.

Qualitative : Contributes to theory building and exploration by generating new insights, challenging existing theories, and uncovering unexpected findings.

Approach : Types

Quantitative :

  • Experimental
  • Quasi-experimental
  • Correlational
  • Descriptive

Qualitative :

  • Ethnography
  • Grounded theory
  • Phenomenology

Population and sampling method

In research, the population, or target population, encompasses all individuals, objects, or events that share the specific attributes you’ve decided are relevant to the study’s objectives. As it is impractical to investigate every individual of this broad population, you will need to choose a subset, or sample.

Starting with a comprehensive understanding of the target population is crucial for selecting a sample that will assure the generalizability of your study’s results. However, drawing a truly random sample can be challenging, often resulting in some degree of sampling bias in most studies.

Sampling strategies vary across research fields, but are generally subdivided into these two categories:

  • Probability Sampling : accurately measurable probability for each member of the target population to have a chance of being included in the sample.
  • Non-probability sampling : selection is non-systematic and does not offer an equal chance for those in the target population to be selected for the sample.

There are several specific sampling methods that fall under these two broad headings:

Probability Sampling Examples

  • Simple random sampling: Each individual is chosen entirely by chance from a population, ensuring equal probability of selection. 
  • Convenience sampling: Participants are selected based on availability and willingness to participate.
  • Systematic sampling: Individuals are selected at regular intervals from the sampling frame based on a systematic rule.
  • Quota sampling: Interviewers are given quotas of specific subjects to recruit.

Non-probability Sampling Examples

  • Stratified sampling: The population is divided into homogenous subgroups based on shared characteristics, then used for a random sample.
  • Judgmental sampling: Researchers select participants based on their judgment or specific criteria.
  • Clustered sampling: Subgroups, or clusters, of the population are determined and then randomly selected for inclusion.
  • Snowball sampling: Existing subjects nominate further subjects known to them, allowing for sampling of hard-to-reach groups.

While they are often resource intensive, probability sampling methods have the advantage of providing representative samples with reduced biases. Non-probability sampling methods, on the other hand, are more cost-effective and convenient, yet lack representativeness and are prone to bias.

Data collection

Throughout the research process, you'll employ a variety of sources to gather, record, and organize information that is relevant to your study or project. Achieving results that hold validity and significance requires the skillful use of efficient data collection methods.

Primary and secondary data collection methods are two distinct approaches to consider when gathering information for your project. Let's take a look at these methods and their associated techniques:

Primary data collection : involves gathering original data directly from the source or through direct interaction with respondents. 

  • Surveys and Questionnaires: collecting data from individuals or groups through face-to-face interviews, telephone calls, mail, or online platforms.
  • Interviews: direct interaction between the researcher and the respondent, conducted in person, over the phone, or through video conferencing.
  • Observations: researchers observe and record behaviors, actions, or events in their natural setting.
  • Experiments: manipulating variables to observe their impact on outcomes. 
  • Focus Groups: small groups of individuals discuss specific topics in a moderated setting.

Secondary data collection: entails collecting and analyzing existing data already collected by someone else for a different purpose.

  • Published sources: books, academic journals, magazines, newspapers, government reports, and other published materials that contain relevant data.
  • Online sources: databases, websites, repositories, and other platforms available for consuming and downloading from the internet. 
  • Government and institutional sources: records, statistics, and other pertinent information to access and purchase.
  • Publicly available data: shared by individuals, organizations, or communities on public stages, websites, or social media.
  • Past research: studies and results available through libraries, educational institutions, and other communal archives. 

Though primary methods offer significant control over data collection, they can be time-consuming, costly, and susceptible to biases. Secondary methods, in contrast, provide cost-effective and time-saving alternatives but offer reduced control over the data collection process.

Data analysis

To extract maximum value from your collected data, it's essential to engage in purposeful evaluation and interpretation. This process of data analysis involves thorough examination, meticulous cleaning, and insightful modeling to reveal patterns pertinent to your research questions.

The choice of methods depends on the specific research objectives, data characteristics, and analytical requirements of your particular project. Here are a few examples of the diverse range of methods you can use for data analysis:

Descriptive statistics : Summarizes key features of the data, like central tendency, spread, and variability. 

Inferential statistics : Draws conclusions about populations based on sample data to test relationships and make predictions.

Qualitative analysis : Considers non-numerical transcripts to identify themes, patterns, and connections.

Causal analysis : Looks at the cause and effect of relationships between variables to test correlations.

Survey and questionnaire analysis : Transforms responses into usable data through processes like cross-tabulation and benchmarking.

Machine learning and data mining : Employs algorithms and computational techniques to discover patterns and insights from large datasets.

By integrating various data analysis tools, you can approach research questions from multiple perspectives to enhance the depth and breadth of your analysis.

Considerations for research design

A meticulous and thorough research design is essential to maintain the quality, reliability, and overall value of your study results. Consider these tips:

Do : Clearly define research questions

Don’t : Rush through the design process

Do : Choose appropriate methods

Don’t : Overlook ethical considerations

Do : Ensure data reliability and validity

Don’t : Neglect practical constraints

Do : Mitigate biases and confounding factors

Don’t : Use overly complex designs

Do : Pilot test the research design

Don’t : Ignore feedback from peers and experts

Do : Document the research design

Don’t : Assume the design is flawless

Final thoughts

A robust research design is undeniably crucial. It sets the framework for data collection, analysis, and interpretation throughout the entire research process. 

Because vagueness and assumptions can jeopardize the success of your project, you must prioritize clarity, make informed choices, and pay meticulous attention to detail. By embracing these strategies, your valuable research has the best chance of making its maximum impact on the world.

The approach is particularly emphasized in the context of community energy research, see Rogers et al. 2008 ; Seyfang et al. 2013 ; also in relation to the sustainability context see Browne et al. 2014 .

Donges ( 2012 : 217) describes from an organisational sociology and systems theory perspective a macro-level as “society and its subsystems”, meso-level composed of the organisations and micro-level as “social action of individuals”. In between he determines a “macro-meso area” in which the organisations move in society as well as a “micro-meso area” in which the individuals and groups act in organisations. See in relation to community energy also the micro-, meso- and macro-division in Devine-Wright 2014 .

Social (emergent or latent) patterns of interaction and interpretation, geneses of meaning, and social dynamics of interaction are not of interest, or recorded (see e.g., Przyborski 2004 ; Deppermann 2008 ; Lamnek 2010 ; Przyborski and Wohlrab-Sahr 2008 ; Medjedović 2014 ; Reichertz 2014 ). A level of content is covered, which mainly concerns procedural-systematic dimensions (e.g., course/process of an assembly or modes and forms of action such as working groups); see on the political science perspective Patzelt 2012 .

Meinefeld sums up by noting: “Qualitative methodology cannot stop at fundamentally rejecting the prior formulation of hypotheses and only allowing ex-post facto hypotheses for the interpretation of the collected material; it must also assign an independent place in its methodological justification to the control of the researcher’s prior knowledge. This does not mean that qualitative social research must always be preceded by elaborate hypotheses oriented towards theories (…). In particular, it cannot be a matter of narrowing social research to the testing of hypotheses. Qualitative methodology, however, cannot continue to adhere to the self-image of having at its disposal a specific access to social phenomena which is free of prior knowledge and which is fundamentally different from the guidance of perception by ex-ante hypotheses. It must develop communicable possibilities to reflect and make explicit the pre-structuring of the object area that also occurs in it” (Meinefeld 1997 : 32).

Porst ( 2014a : 95 f.) mentions here: “use of simple, unambiguous terms that are understood in the same way by all respondents; use of questions with a clear temporal reference; use of answer categories that are exhaustively free of overlap; definition of unclear terms; avoidance of long and complex as well as hypothetical questions; avoidance of double stimuli and negations as well as of insinuations and suggestive questions; avoidance of questions that aim at information that many respondents presumably do not have; the context of a question should not have an (uncontrolled) effect on its answer.”

See Fleiß ( 2011 ) on the use of grounded theory in connection with the typological method.

Metrics details

During the COVID-19 pandemic, simulation-based learning (SBL) serves as an alternative teaching strategy for nursing students facing restricted access to antenatal clinical practicum. However, the factors predicting nursing students’ satisfaction, self-confidence, and their learning experiences remain unclear.

To identify factors predict satisfaction and self-confidence and explore the learning experiences of antenatal SBL.

A Mixed methods research of the cross-sectional study design and descriptive qualitative research was conducted. A total of 100 third year nursing students who finished the Maternity-Newborn Nursing and Midwifery Practice course using antenatal simulation-based learning were invited to complete the online questionnaires. A total of seven questionnaires were administered, including a demographic questionnaire, the Attitude Scale toward Simulation-Based Education (SBE), the Professional Identity Scale for Nursing Students, the Perceived Stress Scale, the Evaluation of Teaching Competencies Scale, the Simulation Design Scale: Student Version, and the Student Satisfaction and Self-Confidence in Learning. The 20 nursing students who completed survey were asked to participate a qualitative focus group discussion. Multiple regression analysis was performed to investigate predictors, while qualitative data were analyzed using content analysis.

The quantitative results showed high levels of satisfaction (mean = 20.55, SD = 3.17) and self-confidence (mean = 32.44, SD = 4.76) after completing the antenatal SBL. In regression analysis, attitude toward SBE (Beta = 0.473, t  = 5.376, p  < 0.001) and attitude toward antenatal care simulation design (Beta = 0.338, t  = 2.611, p  < 0.011) were significantly associated with a high level of satisfaction with antenatal SBL, which accounted for 44.0% of the variance explained in satisfaction. Only attitude toward SBE was significantly associated with a high level of self-confidence in antenatal SBL (Beta = 0.331, t = 3.773, p  < 0.001), which accounted for 45.0% of the variance explained in self-confidence. The qualitative results generated four themes: (1) positive attitude toward antenatal simulation; (2) turning reassurance into confidence; (3) I am really happy to learn; and (4) being a good nurse motivates and stresses me.

Conclusions

Antenatal SBL is an effective teaching strategy that can support nursing students to build clinical confidence. Creating a positive learning environment allows students to have a positive attitude and experience with simulations.

Peer Review reports

Introduction

The COVID-19 pandemic forced many nursing schools to become virtual. Clinical placement experiences transitioned to virtual simulation-based learning (SBL) experiences or reduced hours in the clinic. Simulation-based and virtual education experiences allowed students to complete their education and meet regulatory requirements and supported the future of the nursing workforce [ 1 ]. Undergraduate nursing programs very quickly transitioned from in-person, face-to-face, and clinical learning to remote and virtual simulation learning during the pandemic [ 2 , 3 ].

Simulation helped students enrolled in undergraduate healthcare education understand the theoretical principles and practice key skills in a controlled environment [ 4 ]. The integration of simulation with clinical placements helped students practice clinical behaviors and skills in a safe environment. This enhanced their confidence and encouraged them to transfer their learning to actual care situations in clinical practice [ 4 , 5 ]. SBL had benefits and was used as a substitute for nursing clinical practice [ 6 ] and pre-clinical simulation-based training among undergraduate nursing students [ 7 ]. The pre-clinical simulation could also increase students’ knowledge, skill competencies, confidence, and satisfaction [ 7 ].

Learning through simulation is advantageous for several reasons. It allows for repeated experiences, practice, and individual learning, as well as providing immediate feedback [ 8 ]. SBL has been shown to consistently increase satisfaction with learning among nursing students [ 9 , 10 , 11 ] and promote self-confidence and clinical competence [ 11 , 12 ]. A previous study showed that students who practiced in simulation workshops perceived confidence in performing health teaching and were successful in clinical practice [ 13 ].

Recent studies have explored essential factors related to student confidence and satisfaction according to the National League for Nursing/Laerdal Jeffries Simulation Theory which composed of educational practices, facilitators, participants, simulation design characteristics, and expected outcomes [ 14 ]. The framework is useful for developing, implementing, and evaluating simulation-based activities in nursing education. Factors that affect learning satisfaction and self-confidence in SBL included personal factors such as previous learning outcomes [ 15 ], attitude toward SBL [ 16 , 17 ], professional identity [ 18 , 19 ], perceived stress [ 20 , 21 ], and facilitator factors; teaching competencies [ 11 , 22 ]; and simulation design factors [ 23 ].

Care management during pregnancy is essential for ensuring the quality of care [ 24 ]. With the increase in the constraints of real-world situations, antenatal SBL may be an effective approach to achieving learning outcomes among students. Therefore, effective training with simulation is needed for nursing students to develop the competency to care for pregnant women and achieve learning outcomes. However, few studies have explored the factors associated with nursing students’ confidence and satisfaction related to simulation-based learning in antenatal nursing care. Moreover, nursing students’ experiences and perceptions of the transition from clinic to virtual antenatal simulation training during the COVID-19 pandemic are underexplored.

In contrast to previous studies, our research introduces a novel perspective on nursing practicum training by emphasizing the significance of antenatal SBL and optimizing student learning outcomes amid restricted resources during COVID-19 through a comprehensive understanding.

To assess the usefulness of antenatal simulation in preparing future nurse professionals, we aimed to examine the factors influencing nursing students’ satisfaction and self-confidence levels following antenatal SBL. Additionally, this study aimed to explore nursing students’ learning experiences to better understand their perspectives after completing the antenatal SBL.

Materials and methods

This study was part of a larger study, “The Study of Practicing Learning Outcomes from Clinical Simulation in Maternity-Newborn Nursing and Midwifery Practicum among Nursing Students.” The mixed-methods design followed an explanatory sequential approach [ 25 ]. First, a cross-sectional survey was administered to evaluate the factors influencing nursing students’ satisfaction and self-confidence levels in antenatal SBL during the COVID-19 pandemic. This was followed by a qualitative study in which focus group interviews were conducted to explore the experiences and perspectives of students who completed antenatal SBL.

Participants and setting

The sample size was calculated using the G-power 3.1.9.4 software with the following command for linear multiple regression, effect size f 2 0.15 (medium size) [ 26 ], an alpha level of 0.05, a power of 0.80, and six predictors. Consequently, the calculated sample size is 100 cases. A total of 100 nursing undergraduates from the third year of nursing students who completed the Maternity-Newborn Nursing and Midwifery Practice course and 3 credit hours of clinical work. Inclusion criteria included (1) full-time Thai national students, (2) not previously enrolled in the Maternity-Newborn Nursing and Midwifery Practice course, and (3) having a smartphone or other electronic device to complete the online questionnaire.

This study was conducted at an urban state university in Bangkok involving students enrolled in a baccalaureate nursing program. The antenatal simulation is the clinical part of the Maternity-Newborn Nursing and Midwifery Practice course. In this course, antenatal practical skills for nursing students consisted of (1) an antenatal physical and mental assessment, (2) an abdominal examination for pregnant women over 28 weeks of gestation, and (3) counseling for promoting healthy pregnancy and managing common discomforts. All simulation scenarios were designed and validated by the instructor team according to the course learning outcomes. The onsite simulation was held at the Learning Resource Center. Before starting the scenario, a pre-briefing was conducted by the facilitator to inform the participants of the objectives and rules for simulation learning. During the simulated scenario, other students and the facilitator acted as observers. At the end of the scenario, the facilitator debriefed the students to provide suggestions for improvement and allow them to reflect on their experiences and feelings after completing the scenario.

Data collection

Data were collected between May and December 2022. After finished the Maternity-Newborn Nursing and Midwifery Practice course, nursing students who were recruited into this study and signed consent forms ( n  = 100) were sent the links to an online cross-sectional survey. They were asked to complete them within 48 h. Next, nursing students who completed online survey were asked to participate in a 45–60-minute qualitative focus group discussions (FGDs). Twenty students were separated into four FGDs (five student per group) depended on the satisfaction levels. There were two groups of low-high level of satisfaction scores.

Semi-structured FGDs were conducted by a video call to explore perceptions and experiences related to antenatal SBL during COVID-19. Field notes and a codebook were used for the analysis.

Ethical approval

The study was conducted in accordance with the Declaration of Helsinki and approved by the Institutional Review Boards (or Ethics Committees) of the Faculty of Nursing, Mahidol University (COA No. IRB-NS2022/666.1702). The online consent forms were administrative prior data collection.

A self-administered online survey consisting of three sections was sent to the students via three different links. A total of seven questionnaires were administered as shown in Table  1 . Moreover, a 15-question semi-structured focus group guide was used to collect students’ experiences of the antenatal simulations, which included the following questions: How did you feel after the practice simulation in antenatal care? What were your impression/thoughts about the simulation? What would you change? What were your expectations/goals? How did you achieve them?

Data analysis

Data were analyzed using SPSS version 27. Descriptive statistics were presented as mean and standard deviation (SD) for normally distributed variables. Linear correlation between two variables measured on the same interval or ratio scale was assessed using Pearson’s correlation coefficient ( r ). Multiple linear regression analysis was performed to control for other factors that may affect students’ satisfaction and self-confidence in antenatal simulation-based learning. Factors, including participant factors (cumulative grade point average (GPA), attitude toward SBE, professional identity, and perceived stress), facilitator factors (teaching competencies), and simulation design factors (attitude toward simulation design and perceived important design), were analyzed as independent variables in the regression analysis. Statistical significance was set at a level of 0.05. For qualitative analysis, content analysis was performed on verbatim transcriptions of the recorded interviews, which averaged 60 min each. After the interviews, field notes were recorded to document initial impressions. Data analysis was performed by three members of the research team (KK, SN, and AR) who had various perspectives on simulation-based learning. The researchers worked individually on the transcripts, which were read line-by-line and coded to identify key concepts. Smaller codes were grouped into larger categories, and these categories were grouped into major themes. A concurrent data collection and analysis strategy was used to explore new concepts in subsequent interviews in detail [ 32 ].

Demographic and variable data in the quantitative results

A total of 100 undergraduate nursing students were included in this study. The students’ age was between 20 and 26 years (mean = 21.43, SD = 0.82). More than 90% of the students were female. The independent and dependent variables were presented as percentages and separated into categories in Fig.  1 . The cutoff values were determined as the mean of each variable in Table  2 . Learner satisfaction and self-confidence were treated as dependent variables and demonstrated high levels with antenatal SBE. The mean satisfaction score was 20.55 (SD = 3.17, range 7–25), which showed that the participants were highly satisfied with SBL. Furthermore, participants were very self-confident in SBL, as indicated by the mean self-confidence score of 32.44 (SD = 4.76, range 16–40).

Correlation for the satisfaction and self-confidence level in antenatal SBL according to personal, facilitator, and simulation design factors during the COVID-19 pandemic

Table  2 shows personal, facilitator, and simulation design factors related to satisfaction and self-confidence levels in antenatal simulation. A significant relationship was observed between personal, facilitator, and simulation design factors and students’ satisfaction. Attitude toward SBE ( r  = 0.601, p  < 0.001), professional identity ( r  = 0.244, p  = 0.01), perceived stress ( r  = − 0.255, p  = 0.01), teachers’ competencies ( r  = 0.365, p  < 0.001), attitude toward antenatal care (ANC) simulation design ( r  = 0.484, p  < 0.001), and attitude toward simulation importance ( r  = 0.285, p  = 0.00) were positively correlated with students’ satisfaction. Attitude toward SBE ( r  = 0.534, p  < 0.001), professional identity ( r  = 0.292, p  < 0.001), perceived stress ( r  = − 0.293, p  < 0.01), teachers’ competencies ( r  = 0.468, p  < 0.01), attitude toward simulation design ( r  = 0.519, p  < 0.001), and attitude toward simulation importance ( r  = 0.457, p  < 0.001) were significantly correlated with students’ self-confidence. However, no correlation was observed between cumulative GPA and students’ satisfaction and self-confidence in antenatal SBL.

Predictive factors for students’ satisfaction with antenatal SBL during the COVID-19 pandemic

Table  3 shows personal, facilitator, and simulation design factors associated with students’ satisfaction with antenatal SBL during the COVID-19 pandemic. The regression analysis revealed that attitude toward SBE, a personal factor, was significantly associated with a high level of satisfaction with antenatal SBL (Beta = 0.473, t  = 5.376, p  < 0.001). Additionally, attitude toward ANC simulation design, a simulation design factor, was significantly associated with a high level of satisfaction with ANC simulation learning (Beta = 0.338, t  = 2.611, p  < 0.011). The multiple linear regression model accounted for 44.0% of the variance in satisfaction with ANC simulation learning (adjusted R 2  = 39.0%).

The predictive factors of self-confidence in antenatal SBL during the COVID-19 pandemic

Table  4 shows personal, facilitator, and simulation design factors associated with students’ self-confidence in antenatal SBL during the COVID-19 pandemic. The regression analysis revealed that only attitude toward SBE was significantly associated with a high level of self-confidence in antenatal SBL (Beta = 0.331, t  = 3.773, p  < 0.001). The multiple linear regression model accounted for 45.0% of the variance in self-confidence in ANC simulation learning (adjusted R 2  = 40.0%).

Qualitative results

A total of 20 third year nursing students participated in four focus group interviews. The participants’ age range was 20–24 years, and the average age was 21.55 years (SD = 0.99). The GPA ranged from 2.55 to 3.69 (average 3.20, SD = 0.32). Most participants were female ( n  = 18, 90%). Learner satisfaction scores ranged from 14 to 25 (average 20.75, SD = 4.20). Four major themes were generated, including positive attitude toward antenatal simulation, turning reassurance into confidence, I am really happy to learn, and being a good nurse motivates and stresses me.

Theme 1: positive attitude toward antenatal simulation

Regarding antenatal nursing practices, the simulation-based design was implemented to enhance some of the essential competencies for nurses, such as perinatal history assessment and physical examination, advice for resolving common problems in each trimester of pregnancy, and abdominal examination in pregnancy. The students had a positive attitude toward prenatal simulation. They stated that antenatal simulation could increase their confidence in necessary skills, allow them to make mistakes and correct them, learn the correct practical techniques, prepare them for performing tasks in the ANC clinic, help practice complex cases, and gain patients’ trust. For example, a student disclosed her positive experiences after learning about perinatal history assessment with standardized patients. She learned the step by step process of assessment.

“I think simulation could help me learn step by step correctly after the teacher’s debrief. I think I learn a lot from all situations.” (a student in group 3).

Another student reported that the advantage of simulation is that it allows them to practice several times without putting patients at risk.

“The strengthening points of simulation from my viewpoint were that they allowed me to make something wrong and be able to fix it in the next round. In addition, it could reduce my nervousness in a real-life situation when I approach pregnant women.” (a student in group 2).

Theme 2: turning reassurance into confidence

Many students stated that they received favorable feedback from instructors after simulation learning. Instructors used comments to improve the next set of scenarios. Students who participated in prenatal simulation labs might gain confidence in implementing these procedures in the ANC clinic. For example, a student stated that her antenatal competence improved after completing numerous simulations. She was able to learn and correct her practice and behaviors with the guidance and support of the teacher.

““I believe I have continued to improve my antenatal care competencies. In simulation labs, I practice roughly 3–4 scenarios for which I know the correct advice patterns. When I go to the ANC clinic, I feel comfortable offering advice and performing abdominal examinations on pregnant women.” (a student in group 1)” .

Another student stated that she was impressed by her instructor’s comments. Her instructor generously encouraged her without placing any undue pressure throughout the simulation practices. This instructional style may increase students’ confidence and help them perform better.

“When I used incorrect abdominal examination techniques and educated pregnant women in simulation, my instructor did not blame me. She gave me helpful counsel and discussions for finding a solution. It’s a pleasure to learn from her…” (a student in group 3).

Theme 3: I am really happy to learn

Most students stated that they were happy to learn and practice through antenatal simulation. They reported four factors that influenced their positive emotions during the learning process, including teacher personalities (e.g., unpressured and kind), teaching techniques (e.g., positive reinforcement, positive feedback, and unlimited repetition), standard equipment (adequate), and learning environment (peer). For example, a student stated that she enjoyed learning with the ANC simulation because of the friendly instructor and cheerful teaching manner. She felt comfortable speaking with the teacher.

““I feel this is the most happiness with learning in my nursing student life. I love her [teacher] teaching style. She was not a stressful person. Always, she provides vital points that hit the points of nursing care for pregnant women. I dare [I am confident] and am comfortable discussing with her.” (a student in group 4)” . “ The teachers’ praise is very important in influencing my study intention and increasing my daring [confidence] to practice .” (a student in group 2) .

Another student described his favorite teaching method, which allows peers to give feedback after the simulations. He felt that he could learn from peer support as well.

“I favor my friends who are observers and then give feedback to me. Also, I can observe and give feedback to them as well. It meant that I could learn many cases; we could learn together and fix the weak points in the next cases.” (a student in group 2).

However, students stated that they perceived failure when they received negative feedback. For example, a student expressed her negative experiences and was unhappy to learn.

“If teachers blame us for doing things the wrong way or emphasize our faults rather than solving methods. It’s very bad and makes me very fail and don’t want to learn.” (a student in group 1).

Theme 4: being a good nurse motivates and stresses me

Many students discussed the outcomes of ANC simulation learning, including gaining competencies to give pregnant women accurate, appropriate, and safe nursing care. Other students recognized that their personal and teachers’ expectations could put pressure on them and prevent them from implementing these skills in the real world because they were afraid of making a mistake. For example, a student expressed her expectation that ANC simulation learning allows nursing students to provide correct care, which makes pregnant women trust them.

“I would like to provide the correct care and be able to advise my patients. In addition, I need to receive patients’ trust. It’s quit [a lot of] pressure” (a student in group 4).

Moreover, a student reported that she would like to practice in an ANC simulation clinic several times because it would increase the quality of nursing care provided in the clinic.

“I hope when I have to practice in an ANC clinic, I will give them [pregnant women] the correct and safe care. I hope I will reduce my nervousness and have consciousness.” (a student in group 2).

During the COVID-19 pandemic, simulation learning was developed and implemented as a teaching modality. Nursing is an occupation that requires nursing students to build psychomotor, behavioral, and cognitive skills [ 33 ]. Simulation can be an effective learning experience that increases students’ knowledge and self-confidence and enables the development of clinical decision-making skills [ 17 , 34 ]. However, satisfaction and self-confidence are the main learning outcomes obtained through simulation [ 35 ]. The study results showed that the personal and simulation design factors increased satisfaction and self-confidence in antenatal simulation learning among nursing students.

Attitude toward SBE was a strong significant predictor of students’ self-confidence in antenatal simulation learning. Moreover, the qualitative results showed how students developed their confidence in simulation learning based on teachers’ positive feedback, which allowed them to resolve and remediate skills. In this study, students expressed positive attitudes toward SBE, showing that simulation helped them prepare themselves for practice in the ANC clinic and practice complex cases that would benefit them in the future. However, previous studies have reported several negative opinions from students regarding SBL, including limited equipment/resources, inadequate realistic scenarios reflecting clinical settings, and inadequate space to practice simulation [ 36 , 37 , 38 ]. Furthermore, students have expressed negative emotions such as stress and anxiety [ 39 ]. Thus, it is important to have a positive and nurturing environment and appropriate teaching techniques to increase positive attitudes toward SBE, which strongly impact students’ confidence in learning.

In this study, attitude toward SBE and attitude toward simulation design were strong predictors of students’ satisfaction. Furthermore, many students expressed their satisfaction as a result of the teaching characteristics, simulation design, and positive learning process. Ross et al. [ 40 ] reported that undergraduate nursing students who completed SBL before their clinical practice were satisfied with this education. Additionally, nursing students benefited patients, they were accepted by clinical nurses, and their level of knowledge increased with this education. The simulation design and activities should be based on learners and their needs [ 41 ]. Bagnasco et al. [ 42 ] reported that satisfaction levels were related not only to available materials, instruments, and interactive simulations but also to the trainer’s expertise, approachability, and communication skills. A learning environment that promotes students’ satisfaction enhances motivation to study and increases the chance of meeting expected learning outcomes [ 43 ]. Therefore, the competence of trainers to meet learners’ needs and promote learner engagement should be considered when implementing SBL.

In this study, the qualitative analysis showed that some students accepted that they experienced stress during simulation learning. Experiencing high stress and anxiety levels during practice can decrease concentration in the simulation scenario [ 44 ]. Research studies have reported different causes of learners’ stress. The simulation may cause high stress and anxiety levels because of unfamiliar learning approaches [ 45 ]. Willhaus et al. [ 46 ] showed that nursing students could have negative experiences, such as stress and anxiety, which are often unexpected consequences of the simulation-based practice. The outcomes and expectations for each learning simulation should be clarified, and the level of difficulty should be appropriate for the students.

This study has a limitation. Since the data collection was based on self-administered online surveys where participants were asked about their past simulation learning experience, recall bias may exist. However, a strength of this study lies in its use of a mixed-methods research design, which may reduce self-reported bias [ 47 ] and strengthen the analysis, resulting in comprehensive research outcomes and a better understanding of the learners’ experiences. Furthermore, it serves as a reflection of the impact of instructional management under the constraints of the COVID-19 situation, particularly with limited practical training opportunities. This provides insights into potential paths for the future development of the antenatal SBL training practicum. In future research, it is advisable to design an experimental study that ensures effective outcomes, with a particular focus on assessing the potential impact of antenatal SBL on critical thinking skills. Furthermore, this study provides guidance for practical curriculum design in nursing education and practice, particularly regarding effective antenatal SBL. These implications encompass various aspects, including the preparation process aimed at fostering positive student attitudes toward SBE, enhancing teachers’ competencies in training, designing simulations to cover a range of skills and outcomes to boost student confidence, expanding to promote critical thinking skills, and addressing the psychological well-being of students during implementation.

This study showed that GPA, attitude toward SBE, professional identity, perceived stress, teaching competencies, attitude toward simulation design, and attitude toward simulation importance influenced students’ satisfaction and self-confidence in antenatal SBL. Furthermore, attitude toward SBE and attitude toward simulation design were strong and significant predictors of student satisfaction, whereas attitude toward SBE was the only predictor of student self-confidence. Based on the qualitative analysis, four major themes were identified, including positive attitude toward antenatal simulation, turning reassurance into confidence, I am really happy to learn, and being a good nurse motivates and stresses me. The study results may contribute to the development of learning methods that enhance the effectiveness of antenatal SBL and ensure that nursing students achieve optimal benefits.
