How to Write Limitations of the Study (with examples)
This blog emphasizes the importance of recognizing and effectively writing about limitations in research. It discusses the types of limitations, their significance, and provides guidelines for writing about them, highlighting their role in advancing scholarly research.
Updated on August 24, 2023
No matter how well thought out, every research endeavor encounters challenges. There is simply no way to predict all possible variances throughout the process.
These uncharted boundaries and abrupt constraints are known as limitations in research . Identifying and acknowledging limitations is crucial for conducting rigorous studies. Limitations provide context and shed light on gaps in the prevailing inquiry and literature.
This article explores the importance of recognizing limitations and discusses how to write them effectively. By interpreting limitations in research and considering prevalent examples, we aim to reframe the perception from shameful mistakes to respectable revelations.
What are limitations in research?
In the clearest terms, research limitations are the practical or theoretical shortcomings of a study that are often outside of the researcher’s control . While these weaknesses limit the generalizability of a study’s conclusions, they also present a foundation for future research.
Sometimes limitations arise from tangible circumstances like time and funding constraints, or equipment and participant availability. Other times the rationale is more obscure and buried within the research design. Common types of limitations and their ramifications include:
- Theoretical: limits the scope, depth, or applicability of a study.
- Methodological: limits the quality, quantity, or diversity of the data.
- Empirical: limits the representativeness, validity, or reliability of the data.
- Analytical: limits the accuracy, completeness, or significance of the findings.
- Ethical: limits the access, consent, or confidentiality of the data.
Regardless of how, when, or why they arise, limitations are a natural part of the research process and should never be ignored . Like all other aspects, they are vital in their own purpose.
Why is identifying limitations important?
Whether to seek acceptance or avoid struggle, humans often instinctively hide flaws and mistakes. Merging this thought process into research by attempting to hide limitations, however, is a bad idea. It has the potential to negate the validity of outcomes and damage the reputation of scholars.
By identifying and addressing limitations throughout a project, researchers strengthen their arguments and curtail the chance of peer censure based on overlooked mistakes. Pointing out these flaws shows an understanding of variable limits and a scrupulous research process.
Showing awareness of and taking responsibility for a project’s boundaries and challenges validates the integrity and transparency of a researcher. It further demonstrates the researchers understand the applicable literature and have thoroughly evaluated their chosen research methods.
Presenting limitations also benefits the readers by providing context for research findings. It guides them to interpret the project’s conclusions only within the scope of very specific conditions. By allowing for an appropriate generalization of the findings that is accurately confined by research boundaries and is not too broad, limitations boost a study’s credibility .
Limitations are true assets to the research process. They highlight opportunities for future research. When researchers identify the limitations of their particular approach to a study question, they enable precise transferability and improve chances for reproducibility.
Simply stating a project’s limitations is not adequate for spurring further research, though. To spark the interest of other researchers, these acknowledgements must come with thorough explanations regarding how the limitations affected the current study and how they can potentially be overcome with amended methods.
How to write limitations
Typically, the information about a study’s limitations is situated either at the beginning of the discussion section to provide context for readers or at the conclusion of the discussion section to acknowledge the need for further research. However, it varies depending upon the target journal or publication guidelines.
Don’t hide your limitations
It is also important to not bury a limitation in the body of the paper unless it has a unique connection to a topic in that section. If so, it needs to be reiterated with the other limitations or at the conclusion of the discussion section. Wherever it is included in the manuscript, ensure that the limitations section is prominently positioned and clearly introduced.
While maintaining transparency by disclosing limitations means taking a comprehensive approach, it is not necessary to discuss everything that could have potentially gone wrong during the research study. If there is no commitment to investigation in the introduction, it is unnecessary to consider the issue a limitation to the research. Wholly consider the term ‘limitations’ and ask, “Did it significantly change or limit the possible outcomes?” Then, qualify the occurrence as either a limitation to include in the current manuscript or as an idea to note for other projects.
Writing limitations
Once the limitations are concretely identified and it is decided where they will be included in the paper, researchers are ready for the writing task. Including only what is pertinent, keeping explanations detailed but concise, and employing the following guidelines is key for crafting valuable limitations:
1) Identify and describe the limitations : Clearly introduce the limitation by classifying its form and specifying its origin. For example:
- An unintentional bias encountered during data collection
- An intentional use of unplanned post-hoc data analysis
2) Explain the implications : Describe how the limitation potentially influences the study’s findings and how the validity and generalizability are subsequently impacted. Provide examples and evidence to support claims of the limitations’ effects without making excuses or exaggerating their impact. Overall, be transparent and objective in presenting the limitations, without undermining the significance of the research.
3) Provide alternative approaches for future studies : Offer specific suggestions for potential improvements or avenues for further investigation. Demonstrate a proactive approach by encouraging future research that addresses the identified gaps and, therefore, expands the knowledge base.
Whether presenting limitations as an individual section within the manuscript or as a subtopic in the discussion area, authors should use clear headings and straightforward language to facilitate readability. There is no need to complicate limitations with jargon, computations, or complex datasets.
Examples of common limitations
Limitations are generally grouped into two categories , methodology and research process .
Methodology limitations
Methodology may include limitations due to:
- Sample size
- Lack of available or reliable data
- Lack of prior research studies on the topic
- Measure used to collect the data
- Self-reported data
The researcher is addressing how the large sample size requires a reassessment of the measures used to collect and analyze the data.
Research process limitations
Limitations during the research process may arise from:
- Access to information
- Longitudinal effects
- Cultural and other biases
- Language fluency
- Time constraints
The author is pointing out that the model’s estimates are based on potentially biased observational studies.
Final thoughts
Successfully proving theories and touting great achievements are only two very narrow goals of scholarly research. The true passion and greatest efforts of researchers comes more in the form of confronting assumptions and exploring the obscure.
In many ways, recognizing and sharing the limitations of a research study both allows for and encourages this type of discovery that continuously pushes research forward. By using limitations to provide a transparent account of the project's boundaries and to contextualize the findings, researchers pave the way for even more robust and impactful research in the future.

Diving Deeper into Limitations and Delimitations
If you are working on a thesis, dissertation, or other formal research project, chances are your advisor or committee will ask you to address the delimitations of your study. When faced with this request, many students respond with a puzzled look and then go on to address what are actually the study’s limitations.
In a previous article , we covered what goes into the limitations, delimitations, and assumptions sections of your thesis or dissertation. Here, we will dive a bit deeper into the differences between limitations and delimitations and provide some helpful tips for addressing them in your research project—whether you are working on a quantitative or qualitative study.
Acknowledging Weaknesses vs. Defining Boundaries
These concepts are easy to get confused because both limitations and delimitations restrict (or limit) the questions you’ll be able to answer with your study, most notably in terms of generalizability.
However, the biggest difference between limitations and delimitations is the degree of control you have over them—that is, how much they are based in conscious, intentional choices you made in designing your study.
Limitations occur in all types of research and are, for the most part, outside the researcher’s control (given practical constraints, such as time, funding, and access to populations of interest). They are threats to the study’s internal or external validity.
Limitations may include things such as participant drop-out, a sample that isn’t entirely representative of the desired population, violations to the assumptions of parametric analysis (e.g., normality, homogeneity of variance), the limits of self-report, or the absence of reliability and validity data for some of your survey measures.
Limitations can get in the way of your being able to answer certain questions or draw certain types of inferences from your findings. Therefore, it’s important to acknowledge them upfront and make note of how they restrict the conclusions you’ll be able to draw from your study. Frequently, limitations can get in the way of our ability to generalize our findings to the larger populations or to draw causal conclusions, so be sure to consider these issues when you’re thinking about the potential limitations of your study.
Delimitations are also factors that can restrict the questions you can answer or the inferences you can draw from your findings. However, they are based on intentional choices you make a priori (i.e., as you’re designing the study) about where you’re going to draw the boundaries of your project. In other words, they define the project’s scope.
Like limitations, delimitations are a part of every research project, and this is not a bad thing. In fact, it’s very important! You can’t study everything at once. If you try to do so, your project is bound to get huge and unwieldy, and it will become a lot more difficult to interpret your results or come to meaningful conclusions with so many moving parts. You have to draw the line somewhere, and the delimitations are where you choose to draw these lines.
One of the clearest examples of a delimitation that applies to almost every research project is participant exclusion criteria. In conducting either a quantitative or a qualitative study, you will have to define your population of interest. Defining this population of interest means that you will need to articulate the boundaries of that population (i.e., who is not included). Those boundaries are delimitations.
For example, if you’re interested in understanding the experiences of elementary school teachers who have been implementing a new curriculum into their classrooms, you probably won’t be interviewing or sending a survey to any of the following people: non-teachers, high-school teachers, college professors, principals, parents of elementary school children, or the children themselves. Furthermore, you probably won’t be talking to elementary school teachers who have not yet had the experience of implementing the curriculum in question. You would probably only choose to gather data from elementary school teachers who have had this experience because that is who you’re interested in for the purposes of your study. Perhaps you’ll narrow your focus even more to elementary school teachers in a particular school district who have been teaching for a particular length of time. The possibilities can go on. These are choices you will need to make, both for practical reasons (i.e., the population you have access to) and for the questions you are trying to answer.
Of course, for this particular example, this does not mean that it wouldn’t be interesting to also know what principals think about the new curriculum. Or parents. Or elementary school children. It just means that, for the purposes of your project and your research questions, you’re interested in the experience of the teachers, so you’re excluding anyone who does not meet those criteria. Having delimitations to your population of interest also means that you won’t be able to answer any questions about the experiences of those other populations; this is ok because those populations are outside of the scope of your project . As interesting as their experiences might be, you can save these questions for another study. That is the part of the beauty of research: there will always be more studies to do, more questions to ask. You don’t have to (and can’t) do it all in one project.
Continuing with the previous example, for instance, let’s suppose that the problem you are most interested in addressing is the fact that we know relatively little about elementary school teachers’ experiences of implementing a new curriculum. Perhaps you believe that knowing more about teachers’ experiences could inform their training or help administrators know more about how to support their teachers. If the identified problem is our lack of knowledge about teachers’ experiences, and your research questions focus on better understanding these experiences, that means that you are choosing not to focus on other problems or questions, even those that may seem closely related. For instance, you are not asking how effective the new curriculum is in improving student test scores or graduation rates. You might think that would be a very interesting question, but it will have to wait for another study. In narrowing the focus of your research questions, you limit your ability to answer other questions, and again, that’s ok. These other questions may be interesting and important, but, again, they are beyond the scope of your project .
Common Examples of Limitations
While each study will have its own unique set of limitations, some limitations are more common in quantitative research, and others are more common in qualitative research.
In quantitative research, common limitations include the following:
– Participant dropout
– Small sample size, low power
– Non-representative sample
– Violations of statistical assumptions
– Non-experimental design, lack of manipulation of variables, lack of controls
– Potential confounding variables
– Measures with low (or unknown) reliability or validity
– Limits of an instrument to measure the construct of interest
– Data collection methods (e.g., self-report)
– Anything else that might limit the study’s internal or external validity
In qualitative research, common limitations include the following:
– Lack of generalizability of findings (not the goal of qualitative research, but still worth mentioning as a limitation)
– Inability to draw causal conclusions (again, not the goal of qualitative research, but still worth mentioning)
– Researcher bias/subjectivity (especially if there is only one coder)
– Limitations in participants’ ability/willingness to share or describe their experiences
– Any factors that might limit the rigor of data collection or analysis procedures
Common Examples of Delimitations
As noted above, the two most common sources of delimitations in both quantitative and qualitative research include the following:
– Inclusion/exclusion criteria (or how you define your population of interest)
– Research questions or problems you’ve chosen to examine
Several other common sources of delimitations include the following:
– Theoretical framework or perspective adopted
– Methodological framework or paradigm chosen (e.g., quantitative, qualitative, or mixed-methods)
– In quantitative research, the variables you’ve chosen to measure or manipulate (as opposed to others)
Whether you’re conducting a quantitative or qualitative study, you will (hopefully!) have chosen your research design because it is well suited to the questions you’re hoping to answer. Because these questions define the boundaries or scope of your project and thus point to its delimitations, your research design itself will also be related to these delimitations.
Questions to Ask Yourself
As you are considering the limitations and delimitations of your project, it can be helpful to ask yourself a few different questions.
Questions to help point out your study’s limitations :
1. If I had an unlimited budget, unlimited amounts of time, access to all possible populations, and the ability to manipulate as many variables as I wanted, how would I design my study differently to be better able to answer the questions I want to answer? (The ways in which your study falls short of this will point to its limitations.)
2. Are there design issues that get in the way of my being able to draw causal conclusions?
3. Are there sampling issues that get in the way of my being able to generalize my findings?
4. Are there issues related to the measures I’m using or the methods I’m using to collect data? Do I have concerns about participants telling the truth or being able to provide accurate responses to my questions?
5. Are there any other factors that might limit my study’s internal or external validity?
Questions that help point out your study’s delimitations :
1. What are my exclusion criteria? Who did I not include in my study, and why did I make this choice?
2. What questions did I choose not to address in my study? (Of course, the possibilities are endless here, but consider related questions that you chose not to address.)
3. In what ways did I narrow the scope of my study in order to hone in on a particular issue or question?
4. What other methodologies did I not use that might have allowed me to answer slightly different questions about the same topic?
How to Write About Limitations and Delimitations
Remember, having limitations and delimitations is not a bad thing. They’re present in even the most rigorous research. The important thing is to be aware of them and to acknowledge how they may impact your findings or the conclusions you can draw.
In fact, writing about them and acknowledging them gives you an opportunity to demonstrate that you can think critically about these aspects of your study and how they impact your findings, even if they were out of your control.
Keep in mind that your study’s limitations will likely point to important directions for future research. Therefore, when you’re getting ready to write about your recommendations for future research in your discussion, remember to refer back to your limitations section!
As you write about your delimitations in particular, remember that they are not weaknesses, and you don’t have to apologize for them. Good, strong research projects have clear boundaries. Also, keep in mind that you are the researcher and you can choose whatever delimitations you want for your study. You’re in control of the delimitations. You just have to be prepared—both in your discussion section and in your dissertation defense itself—to justify the choices you make and acknowledge how these choices impact your findings.

Limitations of the Study – How to Write & Examples
What are the limitations of a study?
The limitations of a study are the elements of methodology or study design that impact the interpretation of your research results. The limitations essentially detail any flaws or shortcomings in your study. Study limitations can exist due to constraints on research design, methodology, materials, etc., and these factors may impact the findings of your study. However, researchers are often reluctant to discuss the limitations of their study in their papers, feeling that bringing up limitations may undermine its research value in the eyes of readers and reviewers.
In spite of the impact it might have (and perhaps because of it) you should clearly acknowledge any limitations in your research paper in order to show readers—whether journal editors, other researchers, or the general public—that you are aware of these limitations and to explain how they affect the conclusions that can be drawn from the research.
In this article, we provide some guidelines for writing about research limitations, show examples of some frequently seen study limitations, and recommend techniques for presenting this information. And after you have finished drafting and have received manuscript editing for your work, you still might want to follow this up with academic editing before submitting your work to your target journal.
Why do I need to include limitations of research in my paper?
Although limitations address the potential weaknesses of a study, writing about them toward the end of your paper actually strengthens your study by identifying any problems before other researchers or reviewers find them.
Furthermore, pointing out study limitations shows that you’ve considered the impact of research weakness thoroughly and have an in-depth understanding of your research topic. Since all studies face limitations, being honest and detailing these limitations will impress researchers and reviewers more than ignoring them.
Where should I put the limitations of the study in my paper?
Some limitations might be evident to researchers before the start of the study, while others might become clear while you are conducting the research. Whether these limitations are anticipated or not, and whether they are due to research design or to methodology, they should be clearly identified and discussed in the discussion section —the final section of your paper. Most journals now require you to include a discussion of potential limitations of your work, and many journals now ask you to place this “limitations section” at the very end of your article.
Some journals ask you to also discuss the strengths of your work in this section, and some allow you to freely choose where to include that information in your discussion section—make sure to always check the author instructions of your target journal before you finalize a manuscript and submit it for peer review .
Limitations of the Study Examples
There are several reasons why limitations of research might exist. The two main categories of limitations are those that result from the methodology and those that result from issues with the researcher(s).
Common Methodological Limitations of Studies
Limitations of research due to methodological problems can be addressed by clearly and directly identifying the potential problem and suggesting ways in which this could have been addressed—and SHOULD be addressed in future studies. The following are some major potential methodological issues that can impact the conclusions researchers can draw from the research.
Issues with research samples and selection
Sampling errors occur when a probability sampling method is used to select a sample, but that sample does not reflect the general population or appropriate population concerned. This results in limitations of your study known as “sample bias” or “selection bias.”
For example, if you conducted a survey to obtain your research results, your samples (participants) were asked to respond to the survey questions. However, you might have had limited ability to gain access to the appropriate type or geographic scope of participants. In this case, the people who responded to your survey questions may not truly be a random sample.
Insufficient sample size for statistical measurements
When conducting a study, it is important to have a sufficient sample size in order to draw valid conclusions. The larger the sample, the more precise your results will be. If your sample size is too small, it will be difficult to identify significant relationships in the data.
Normally, statistical tests require a larger sample size to ensure that the sample is considered representative of a population and that the statistical result can be generalized to a larger population. It is a good idea to understand how to choose an appropriate sample size before you conduct your research by using scientific calculation tools—in fact, many journals now require such estimation to be included in every manuscript that is sent out for review.
Lack of previous research studies on the topic
Citing and referencing prior research studies constitutes the basis of the literature review for your thesis or study, and these prior studies provide the theoretical foundations for the research question you are investigating. However, depending on the scope of your research topic, prior research studies that are relevant to your thesis might be limited.
When there is very little or no prior research on a specific topic, you may need to develop an entirely new research typology. In this case, discovering a limitation can be considered an important opportunity to identify literature gaps and to present the need for further development in the area of study.
Methods/instruments/techniques used to collect the data
After you complete your analysis of the research findings (in the discussion section), you might realize that the manner in which you have collected the data or the ways in which you have measured variables has limited your ability to conduct a thorough analysis of the results.
For example, you might realize that you should have addressed your survey questions from another viable perspective, or that you were not able to include an important question in the survey. In these cases, you should acknowledge the deficiency or deficiencies by stating a need for future researchers to revise their specific methods for collecting data that includes these missing elements.
Common Limitations of the Researcher(s)
Study limitations that arise from situations relating to the researcher or researchers (whether the direct fault of the individuals or not) should also be addressed and dealt with, and remedies to decrease these limitations—both hypothetically in your study, and practically in future studies—should be proposed.
Limited access to data
If your research involved surveying certain people or organizations, you might have faced the problem of having limited access to these respondents. Due to this limited access, you might need to redesign or restructure your research in a different way. In this case, explain the reasons for limited access and be sure that your finding is still reliable and valid despite this limitation.
Time constraints
Just as students have deadlines to turn in their class papers, academic researchers might also have to meet deadlines for submitting a manuscript to a journal or face other time constraints related to their research (e.g., participants are only available during a certain period; funding runs out; collaborators move to a new institution). The time available to study a research problem and to measure change over time might be constrained by such practical issues. If time constraints negatively impacted your study in any way, acknowledge this impact by mentioning a need for a future study (e.g., a longitudinal study) to answer this research problem.
Conflicts arising from cultural bias and other personal issues
Researchers might hold biased views due to their cultural backgrounds or perspectives of certain phenomena, and this can affect a study’s legitimacy. Also, it is possible that researchers will have biases toward data and results that only support their hypotheses or arguments. In order to avoid these problems, the author(s) of a study should examine whether the way the research problem was stated and the data-gathering process was carried out appropriately.
Steps for Organizing Your Study Limitations Section
When you discuss the limitations of your study, don’t simply list and describe your limitations—explain how these limitations have influenced your research findings. There might be multiple limitations in your study, but you only need to point out and explain those that directly relate to and impact how you address your research questions.
We suggest that you divide your limitations section into three steps: (1) identify the study limitations; (2) explain how they impact your study in detail; and (3) propose a direction for future studies and present alternatives. By following this sequence when discussing your study’s limitations, you will be able to clearly demonstrate your study’s weakness without undermining the quality and integrity of your research.
Step 1. Identify the limitation(s) of the study
- This part should comprise around 10%-20% of your discussion of study limitations.
The first step is to identify the particular limitation(s) that affected your study. There are many possible limitations of research that can affect your study, but you don’t need to write a long review of all possible study limitations. A 200-500 word critique is an appropriate length for a research limitations section. In the beginning of this section, identify what limitations your study has faced and how important these limitations are.
You only need to identify limitations that had the greatest potential impact on: (1) the quality of your findings, and (2) your ability to answer your research question.
Step 2. Explain these study limitations in detail
- This part should comprise around 60-70% of your discussion of limitations.
After identifying your research limitations, it’s time to explain the nature of the limitations and how they potentially impacted your study. For example, when you conduct quantitative research, a lack of probability sampling is an important issue that you should mention. On the other hand, when you conduct qualitative research, the inability to generalize the research findings could be an issue that deserves mention.
Explain the role these limitations played on the results and implications of the research and justify the choice you made in using this “limiting” methodology or other action in your research. Also, make sure that these limitations didn’t undermine the quality of your dissertation .
Step 3. Propose a direction for future studies and present alternatives (optional)
- This part should comprise around 10-20% of your discussion of limitations.
After acknowledging the limitations of the research, you need to discuss some possible ways to overcome these limitations in future studies. One way to do this is to present alternative methodologies and ways to avoid issues with, or “fill in the gaps of” the limitations of this study you have presented. Discuss both the pros and cons of these alternatives and clearly explain why researchers should choose these approaches.
Make sure you are current on approaches used by prior studies and the impacts they have had on their findings. Cite review articles or scientific bodies that have recommended these approaches and why. This might be evidence in support of the approach you chose, or it might be the reason you consider your choices to be included as limitations. This process can act as a justification for your approach and a defense of your decision to take it while acknowledging the feasibility of other approaches.
P hrases and Tips for Introducing Your Study Limitations in the Discussion Section
The following phrases are frequently used to introduce the limitations of the study:
- “There may be some possible limitations in this study.”
- “The findings of this study have to be seen in light of some limitations.”
- “The first is the…The second limitation concerns the…”
- “The empirical results reported herein should be considered in the light of some limitations.”
- “This research, however, is subject to several limitations.”
- “The primary limitation to the generalization of these results is…”
- “Nonetheless, these results must be interpreted with caution and a number of limitations should be borne in mind.”
- “As with the majority of studies, the design of the current study is subject to limitations.”
- “There are two major limitations in this study that could be addressed in future research. First, the study focused on …. Second ….”

The limitations section: Common Limitations in Research
Every dissertation should include a limitations section in which you recognise the limits and weaknesses of your research, so here are a few tips on what to cover.
Research, by its nature, is a dynamic and iterative process that aims to explore, analyze, and contribute to knowledge in various fields. However, every research endeavour comes with its set of limitations that researchers must acknowledge, address, and navigate. In this blog post, we’ll delve into the common limitations of research and discuss strategies for mitigating their impact on the validity, reliability, and generalizability of findings.
Five main types of limitations
1. sampling limitations:.
- Sample Size: Limited sample size can affect the generalizability and representativeness of research findings. Small samples may not adequately capture the diversity or variability within a population, leading to potential biases or limited statistical power.
- Sampling Bias: Biases in sample selection, such as self-selection bias or sampling from non-representative populations, can compromise the external validity of research outcomes.
2. Measurement and Instrumentation Limitations:
- Measurement Error: Inaccuracies or inconsistencies in measurement instruments, data collection tools, or operational definitions can introduce measurement error, affecting the reliability and validity of results.
- Validity Threats: Threats to internal validity (e.g., confounding variables, selection bias) or external validity (e.g., ecological validity, population validity) can impact the robustness and generalizability of research findings.
3. Methodological Limitations:
- Research Design: Limitations in research design, such as lack of control groups, non-randomized designs, or cross-sectional studies, can constrain the ability to establish causal relationships or infer causality.
- Data Collection Methods: Issues related to data collection methods, such as self-report biases, social desirability biases, or retrospective data, can introduce inaccuracies or distortions in data interpretation.
4. Contextual and External Factors:
- Contextual Constraints: Research conducted in specific contexts or settings may face limitations in generalizing findings to broader populations or different contexts.
- Temporal Limitations: Changes over time, evolving trends, or temporal fluctuations can impact the relevance and applicability of research findings beyond a specific timeframe.
5. Ethical and Practical Constraints:
- Ethical Considerations: Ethical constraints, such as limitations in accessing sensitive data, obtaining informed consent, or ensuring participant confidentiality, can influence the scope and conduct of research.
- Resource Constraints: Practical limitations, such as budget constraints, time constraints, or access to resources (e.g., data, equipment, expertise), can impact the feasibility and scope of research endeavours.
Strategies for Addressing Limitations:
- Transparent Reporting: Clearly articulate and disclose limitations in research methodology, sampling, measurement, and design in research reports, ensuring transparency and accountability.
- Mitigating Biases: Implement strategies to mitigate biases, such as randomization, blinding, control measures, and sensitivity analyses, to enhance the validity and reliability of findings.
- Sensitivity Analyses: Conduct sensitivity analyses or robustness checks to assess the impact of potential biases, outliers, or variations in data on research outcomes.
- Triangulation: Employ triangulation methods, combining multiple data sources, methods, or perspectives, to enhance the validity, reliability, and depth of research findings.
- Longitudinal Studies: Consider longitudinal or follow-up studies to track changes over time, validate findings, and assess the stability of research outcomes.
While every research endeavour has its limitations, acknowledging and addressing these limitations is crucial for maintaining the integrity, rigour, and credibility of research findings. Also, every dissertation should include a limitations section. By adopting transparent reporting practices, implementing mitigation strategies, conducting sensitivity analyses, leveraging triangulation methods, and considering longitudinal approaches, researchers can navigate common limitations effectively and enhance the robustness and applicability of their research contributions.

The limitations of the study are those characteristics of design or methodology that impacted or influenced the application or interpretation of the results of your study. They are the constraints on generalizability and utility of findings that are the result of the ways in which you chose to design the study and/or the method used to establish internal and external validity.
Importance of...
Always acknowledge a study's limitations. It is far better for you to identify and acknowledge your study’s limitations than to have them pointed out by your professor and be graded down because you appear to have ignored them.
Keep in mind that acknowledgement of a study's limitations is an opportunity to make suggestions for further research. If you do connect your study's limitations to suggestions for further research, be sure to explain the ways in which these unanswered questions may become more focused because of your study.
Acknowledgement of a study's limitations also provides you with an opportunity to demonstrate to your professor that you have thought critically about the research problem, understood the relevant literature published about it, and correctly assessed the methods chosen for studying the problem. A key objective of the research process is not only discovering new knowledge but also to confront assumptions and explore what we don't know.
Claiming limitiations is a subjective process because you must evaluate the impact of those limitations . Don't just list key weaknesses and the magnitude of a study's limitations. To do so diminishes the validity of your research because it leaves the reader wondering whether, or in what ways, limitation(s) in your study may have impacted the findings and conclusions. Limitations require a critical, overall appraisal and interpretation of their impact. You should answer the question: do these problems with errors, methods, validity, etc. eventually matter and, if so, to what extent?

Descriptions of Possible Limitations
All studies have limitations . However, it is important that you restrict your discussion to limitations related to the research problem under investigation. For example, if a meta-analysis of existing literature is not a stated purpose of your research, it should not be discussed as a limitation. Do not apologize for not addressing issues that you did not promise to investigate in your paper.
Here are examples of limitations you may need to describe and to discuss how they possibly impacted your findings. Descriptions of limitations should be stated in the past tense.
Possible Methodological Limitations
- Sample size -- the number of the units of analysis you use in your study is dictated by the type of research problem you are investigating. Note that, if your sample size is too small, it will be difficult to find significant relationships from the data, as statistical tests normally require a larger sample size to ensure a representative distribution of the population and to be considered representative of groups of people to whom results will be generalized or transferred.
- Lack of available and/or reliable data -- a lack of data or of reliable data will likely require you to limit the scope of your analysis, the size of your sample, or it can be a significant obstacle in finding a trend and a meaningful relationship. You need to not only describe these limitations but to offer reasons why you believe data is missing or is unreliable. However, don’t just throw up your hands in frustration; use this as an opportunity to describe the need for future research.
- Lack of prior research studies on the topic -- citing prior research studies forms the basis of your literature review and helps lay a foundation for understanding the research problem you are investigating. Depending on the currency or scope of your research topic, there may be little, if any, prior research on your topic. Before assuming this to be true, consult with a librarian! In cases when a librarian has confirmed that there is a lack of prior research, you may be required to develop an entirely new research typology [for example, using an exploratory rather than an explanatory research design]. Note that this limitation can serve as an important opportunity to describe the need for further research.
- Measure used to collect the data -- sometimes it is the case that, after completing your interpretation of the findings, you discover that the way in which you gathered data inhibited your ability to conduct a thorough analysis of the results. For example, you regret not including a specific question in a survey that, in retrospect, could have helped address a particular issue that emerged later in the study. Acknowledge the deficiency by stating a need in future research to revise the specific method for gathering data.
- Self-reported data -- whether you are relying on pre-existing self-reported data or you are conducting a qualitative research study and gathering the data yourself, self-reported data is limited by the fact that it rarely can be independently verified. In other words, you have to take what people say, whether in interviews, focus groups, or on questionnaires, at face value. However, self-reported data contain several potential sources of bias that should be noted as limitations: (1) selective memory (remembering or not remembering experiences or events that occurred at some point in the past); (2) telescoping [recalling events that occurred at one time as if they occurred at another time]; (3) attribution [the act of attributing positive events and outcomes to one's own agency but attributing negative events and outcomes to external forces]; and, (4) exaggeration [the act of representing outcomes or embellishing events as more significant than is actually suggested from other data].
Possible Limitations of the Researcher
- Access -- if your study depends on having access to people, organizations, or documents and, for whatever reason, access is denied or otherwise limited, the reasons for this need to be described.
- Longitudinal effects -- unlike your professor, who can literally devote years [even a lifetime] to studying a single research problem, the time available to investigate a research problem and to measure change or stability within a sample is constrained by the due date of your assignment. Be sure to choose a topic that does not require an excessive amount of time to complete the literature review, apply the methodology, and gather and interpret the results. If you're unsure, talk to your professor.
- Cultural and other type of bias -- we all have biases, whether we are conscience of them or not. Bias is when a person, place, or thing is viewed or shown in a consistently inaccurate way. It is usually negative, though one can have a positive bias as well. When proof-reading your paper, be especially critical in reviewing how you have stated a problem, selected the data to be studied, what may have been omitted, the manner in which you have ordered events, people, or places and how you have chosen to represent a person, place, or thing, to name a phenomenon, or to use possible words with a positive or negative connotation. Note that if you detect bias in prior research, it must be acknowledged and you should explain what measures were taken to avoid perpetuating bias.
- Fluency in a language -- if your research focuses on measuring the perceived value of after-school tutoring among Mexican-American ESL [English as a Second Language] students, for example, and you are not fluent in Spanish, you are limited in being able to read and interpret Spanish language research studies on the topic. This deficiency should be acknowledged.

Structure and Writing Style
Information about the limitations of your study are generally placed either at the beginning of the discussion section of your paper so the reader knows and understands the limitations before reading the rest of your analysis of the findings, or, the limitations are outlined at the conclusion of the discussion section as an acknowledgement of the need for further study. Statements about a study's limitations should not be buried in the body [middle] of the discussion section unless a limitation is specific to something covered in that part of the paper. If this is the case, though, the limitation should be reiterated at the conclusion of the section.
If you determine that your study is seriously flawed due to important limitations , such as, an inability to acquire critical data, consider reframing it as a pilot study intended to lay the groundwork for a more complete research study in the future. Be sure, though, to specifically explain the ways that these flaws can be successfully overcome in later studies.
But, do not use this as an excuse for not developing a thorough research paper! Review the tab in this guide for developing a research topic . If serious limitations exist, it generally indicates a likelihood that your research problem is too narrowly defined or that the issue or event under study is too recent and, thus, very little research has been written about it. If serious limitations do emerge, consult with your professor about possible ways to overcome them or how to reframe your study.
When discussing the limitations of your research, be sure to:
- Describe each limitation in detailed but concise terms;
- Explain why each limitation exists;
- Provide the reasons why each limitation could not be overcome using the method(s) chosen to gather the data [cite to other studies that had similar problems when possible];
- Assess the impact of each limitation in relation to the overall findings and conclusions of your study; and,
- If appropriate, describe how these limitations could point to the need for further research.
Remember that the method you chose may be the source of a significant limitation that has emerged during your interpretation of the results [for example, you didn't ask a particular question in a survey that you later wish you had]. If this is the case, don't panic. Acknowledge it, and explain how applying a different or more robust methodology might address the research problem more effectively in any future study. A underlying goal of scholarly research is not only to prove what works, but to demonstrate what doesn't work or what needs further clarification.

Writing Tip
Don't Inflate the Importance of Your Findings! After all the hard work and long hours devoted to writing your research paper, it is easy to get carried away with attributing unwarranted importance to what you’ve done. We all want our academic work to be viewed as excellent and worthy of a good grade, but it is important that you understand and openly acknowledge the limitiations of your study. Inflating of the importance of your study's findings in an attempt hide its flaws is a big turn off to your readers. A measure of humility goes a long way!
Another Writing Tip
Negative Results are Not a Limitation!
Negative evidence refers to findings that unexpectedly challenge rather than support your hypothesis. If you didn't get the results you anticipated, it may mean your hypothesis was incorrect and needs to be reformulated, or, perhaps you have stumbled onto something unexpected that warrants further study. Moreover, the absence of an effect may be very telling in many situations, particularly in experimental research designs. In any case, your results may be of importance to others even though they did not support your hypothesis. Do not fall into the trap of thinking that results contrary to what you expected is a limitation to your study. If you carried out the research well, they are simply your results and only require additional interpretation.
Yet Another Writing Tip
A Note about Sample Size Limitations in Qualitative Research
Sample sizes are typically smaller in qualitative research because, as the study goes on, acquiring more data does not necessarily lead to more information. This is because one occurrence of a piece of data, or a code, is all that is necessary to ensure that it becomes part of the analysis framework. However, it remains true that sample sizes that are too small cannot adequately support claims of having achieved valid conclusions and sample sizes that are too large do not permit the deep, naturalistic, and inductive analysis that defines qualitative inquiry. Determining adequate sample size in qualitative research is ultimately a matter of judgment and experience in evaluating the quality of the information collected against the uses to which it will be applied and the particular research method and purposeful sampling strategy employed. If the sample size is found to be a limitation, it may reflect your judgement about the methodological technique chosen [e.g., single life history study versus focus group interviews] rather than the number of respondents used.

How to Write a Discussion Section | Tips & Examples
Published on 21 August 2022 by Shona McCombes . Revised on 25 October 2022.
The discussion section is where you delve into the meaning, importance, and relevance of your results .
It should focus on explaining and evaluating what you found, showing how it relates to your literature review , and making an argument in support of your overall conclusion . It should not be a second results section .
There are different ways to write this section, but you can focus your writing around these key elements:
- Summary: A brief recap of your key results
- Interpretations: What do your results mean?
- Implications: Why do your results matter?
- Limitations: What can’t your results tell us?
- Recommendations: Avenues for further studies or analyses

What not to include in your discussion section, step 1: summarise your key findings, step 2: give your interpretations, step 3: discuss the implications, step 4: acknowledge the limitations, step 5: share your recommendations, discussion section example.
There are a few common mistakes to avoid when writing the discussion section of your paper.
- Don’t introduce new results: You should only discuss the data that you have already reported in your results section .
- Don’t make inflated claims: Avoid overinterpretation and speculation that isn’t directly supported by your data.
- Don’t undermine your research: The discussion of limitations should aim to strengthen your credibility, not emphasise weaknesses or failures.

Correct my document today
Start this section by reiterating your research problem and concisely summarising your major findings. Don’t just repeat all the data you have already reported – aim for a clear statement of the overall result that directly answers your main research question . This should be no more than one paragraph.
Many students struggle with the differences between a discussion section and a results section . The crux of the matter is that your results sections should present your results, and your discussion section should subjectively evaluate them. Try not to blend elements of these two sections, in order to keep your paper sharp.
- The results indicate that …
- The study demonstrates a correlation between …
- This analysis supports the theory that …
- The data suggest that …
The meaning of your results may seem obvious to you, but it’s important to spell out their significance for your reader, showing exactly how they answer your research question.
The form of your interpretations will depend on the type of research, but some typical approaches to interpreting the data include:
- Identifying correlations , patterns, and relationships among the data
- Discussing whether the results met your expectations or supported your hypotheses
- Contextualising your findings within previous research and theory
- Explaining unexpected results and evaluating their significance
- Considering possible alternative explanations and making an argument for your position
You can organise your discussion around key themes, hypotheses, or research questions, following the same structure as your results section. Alternatively, you can also begin by highlighting the most significant or unexpected results.
- In line with the hypothesis …
- Contrary to the hypothesised association …
- The results contradict the claims of Smith (2007) that …
- The results might suggest that x . However, based on the findings of similar studies, a more plausible explanation is x .
As well as giving your own interpretations, make sure to relate your results back to the scholarly work that you surveyed in the literature review . The discussion should show how your findings fit with existing knowledge, what new insights they contribute, and what consequences they have for theory or practice.
Ask yourself these questions:
- Do your results support or challenge existing theories? If they support existing theories, what new information do they contribute? If they challenge existing theories, why do you think that is?
- Are there any practical implications?
Your overall aim is to show the reader exactly what your research has contributed, and why they should care.
- These results build on existing evidence of …
- The results do not fit with the theory that …
- The experiment provides a new insight into the relationship between …
- These results should be taken into account when considering how to …
- The data contribute a clearer understanding of …
- While previous research has focused on x , these results demonstrate that y .
Prevent plagiarism, run a free check.
Even the best research has its limitations. Acknowledging these is important to demonstrate your credibility. Limitations aren’t about listing your errors, but about providing an accurate picture of what can and cannot be concluded from your study.
Limitations might be due to your overall research design, specific methodological choices , or unanticipated obstacles that emerged during your research process.
Here are a few common possibilities:
- If your sample size was small or limited to a specific group of people, explain how generalisability is limited.
- If you encountered problems when gathering or analysing data, explain how these influenced the results.
- If there are potential confounding variables that you were unable to control, acknowledge the effect these may have had.
After noting the limitations, you can reiterate why the results are nonetheless valid for the purpose of answering your research question.
- The generalisability of the results is limited by …
- The reliability of these data is impacted by …
- Due to the lack of data on x , the results cannot confirm …
- The methodological choices were constrained by …
- It is beyond the scope of this study to …
Based on the discussion of your results, you can make recommendations for practical implementation or further research. Sometimes, the recommendations are saved for the conclusion .
Suggestions for further research can lead directly from the limitations. Don’t just state that more studies should be done – give concrete ideas for how future work can build on areas that your own research was unable to address.
- Further research is needed to establish …
- Future studies should take into account …
- Avenues for future research include …

Writing your dissertation - structure and sections
Posted in: dissertations
In this post, we look at the structural elements of a typical dissertation. Your department may wish you to include additional sections but the following covers all core elements you will need to work on when designing and developing your final assignment.
The table below illustrates a classic dissertation layout with approximate lengths for each section.
Hopkins, D. and Reid, T., 2018. The Academic Skills Handbook: Your Guid e to Success in Writing, Thinking and Communicating at University . Sage.
Your title should be clear, succinct and tell the reader exactly what your dissertation is about. If it is too vague or confusing, then it is likely your dissertation will be too vague and confusing. It is important therefore to spend time on this to ensure you get it right, and be ready to adapt to fit any changes of direction in your research or focus.
In the following examples, across a variety of subjects, you can see how the students have clearly identified the focus of their dissertation, and in some cases target a problem that they will address:
An econometric analysis of the demand for road transport within the united Kingdom from 1965 to 2000
To what extent does payment card fraud affect UK bank profitability and bank stakeholders? Does this justify fraud prevention?
A meta-analysis of implant materials for intervertebral disc replacement and regeneration.
The role of ethnic institutions in social development; the case of Mombasa, Kenya.
Why haven’t biomass crops been adopted more widely as a source of renewable energy in the United Kingdom?
Mapping the criminal mind: Profiling and its limitation.
The Relative Effectiveness of Interferon Therapy for Chronic Hepatitis C
Under what conditions did the European Union exhibit leadership in international climate change negotiations from 1992-1997, 1997-2005 and 2005-Copenhagen respectively?
The first thing your reader will read (after the title) is your abstract. However, you need to write this last. Your abstract is a summary of the whole project, and will include aims and objectives, methods, results and conclusions. You cannot write this until you have completed your write-up.
Introduction
Your introduction should include the same elements found in most academic essay or report assignments, with the possible inclusion of research questions. The aim of the introduction is to set the scene, contextualise your research, introduce your focus topic and research questions, and tell the reader what you will be covering. It should move from the general and work towards the specific. You should include the following:
- Attention-grabbing statement (a controversy, a topical issue, a contentious view, a recent problem etc)
- Background and context
- Introduce the topic, key theories, concepts, terms of reference, practices, (advocates and critic)
- Introduce the problem and focus of your research
- Set out your research question(s) (this could be set out in a separate section)
- Your approach to answering your research questions.
Literature review
Your literature review is the section of your report where you show what is already known about the area under investigation and demonstrate the need for your particular study. This is a significant section in your dissertation (30%) and you should allow plenty of time to carry out a thorough exploration of your focus topic and use it to help you identify a specific problem and formulate your research questions.
You should approach the literature review with the critical analysis dial turned up to full volume. This is not simply a description, list, or summary of everything you have read. Instead, it is a synthesis of your reading, and should include analysis and evaluation of readings, evidence, studies and data, cases, real world applications and views/opinions expressed. Your supervisor is looking for this detailed critical approach in your literature review, where you unpack sources, identify strengths and weaknesses and find gaps in the research.
In other words, your literature review is your opportunity to show the reader why your paper is important and your research is significant, as it addresses the gap or on-going issue you have uncovered.
You need to tell the reader what was done. This means describing the research methods and explaining your choice. This will include information on the following:
- Are your methods qualitative or quantitative... or both? And if so, why?
- Who (if any) are the participants?
- Are you analysing any documents, systems, organisations? If so what are they and why are you analysing them?
- What did you do first, second, etc?
- What ethical considerations are there?
It is a common style convention to write what was done rather than what you did, and write it so that someone else would be able to replicate your study.
Here you describe what you have found out. You need to identify the most significant patterns in your data, and use tables and figures to support your description. Your tables and figures are a visual representation of your findings, but remember to describe what they show in your writing. There should be no critical analysis in this part (unless you have combined results and discussion sections).
Here you show the significance of your results or findings. You critically analyse what they mean, and what the implications may be. Talk about any limitations to your study, evaluating the strengths and weaknesses of your own research, and make suggestions for further studies to build on your findings. In this section, your supervisor will expect you to dig deep into your findings and critically evaluate what they mean in relation to previous studies, theories, views and opinions.
This is a summary of your project, reminding the reader of the background to your study, your objectives, and showing how you met them. Do not include any new information that you have not discussed before.
This is the list of all the sources you have cited in your dissertation. Ensure you are consistent and follow the conventions for the particular referencing system you are using. (Note: you shouldn't include books you've read but do not appear in your dissertation).
Include any extra information that your reader may like to read. It should not be essential for your reader to read them in order to understand your dissertation. Your appendices should be labelled (e.g. Appendix A, Appendix B, etc). Examples of material for the appendices include detailed data tables (summarised in your results section), the complete version of a document you have used an extract from, etc.

Descriptions of Possible Limitations
All studies have limitations . However, it is important that you restrict your discussion to limitations related to the research problem under investigation. For example, if a meta-analysis of existing literature is not a stated purpose of your research, it should not be discussed as a limitation. Do not apologize for not addressing issues that you did not promise to investigate in the introduction of your paper.
Here are examples of limitations related to methodology and the research process you may need to describe and to discuss how they possibly impacted your results. Descriptions of limitations should be stated in the past tense because they were discovered after you completed your research.
Possible Methodological Limitations
- Sample size -- the number of the units of analysis you use in your study is dictated by the type of research problem you are investigating. Note that, if your sample size is too small, it will be difficult to find significant relationships from the data, as statistical tests normally require a larger sample size to ensure a representative distribution of the population and to be considered representative of groups of people to whom results will be generalized or transferred. Note that sample size is less relevant in qualitative research.
- Lack of available and/or reliable data -- a lack of data or of reliable data will likely require you to limit the scope of your analysis, the size of your sample, or it can be a significant obstacle in finding a trend and a meaningful relationship. You need to not only describe these limitations but to offer reasons why you believe data is missing or is unreliable. However, don’t just throw up your hands in frustration; use this as an opportunity to describe the need for future research.
- Lack of prior research studies on the topic -- citing prior research studies forms the basis of your literature review and helps lay a foundation for understanding the research problem you are investigating. Depending on the currency or scope of your research topic, there may be little, if any, prior research on your topic. Before assuming this to be true, though, consult with a librarian. In cases when a librarian has confirmed that there is no prior research, you may be required to develop an entirely new research typology [for example, using an exploratory rather than an explanatory research design]. Note again that discovering a limitation can serve as an important opportunity to identify new gaps in the literature and to describe the need for further research.
- Measure used to collect the data -- sometimes it is the case that, after completing your interpretation of the findings, you discover that the way in which you gathered data inhibited your ability to conduct a thorough analysis of the results. For example, you regret not including a specific question in a survey that, in retrospect, could have helped address a particular issue that emerged later in the study. Acknowledge the deficiency by stating a need for future researchers to revise the specific method for gathering data.
- Self-reported data -- whether you are relying on pre-existing data or you are conducting a qualitative research study and gathering the data yourself, self-reported data is limited by the fact that it rarely can be independently verified. In other words, you have to take what people say, whether in interviews, focus groups, or on questionnaires, at face value. However, self-reported data can contain several potential sources of bias that you should be alert to and note as limitations. These biases become apparent if they are incongruent with data from other sources. These are: (1) selective memory [remembering or not remembering experiences or events that occurred at some point in the past]; (2) telescoping [recalling events that occurred at one time as if they occurred at another time]; (3) attribution [the act of attributing positive events and outcomes to one's own agency but attributing negative events and outcomes to external forces]; and, (4) exaggeration [the act of representing outcomes or embellishing events as more significant than is actually suggested from other data].
Possible Limitations of the Researcher
- Access -- if your study depends on having access to people, organizations, or documents and, for whatever reason, access is denied or limited in some way, the reasons for this need to be described.
- Longitudinal effects -- unlike your professor, who can literally devote years [even a lifetime] to studying a single topic, the time available to investigate a research problem and to measure change or stability over time is pretty much constrained by the due date of your assignment. Be sure to choose a research problem that does not require an excessive amount of time to complete the literature review, apply the methodology, and gather and interpret the results. If you're unsure whether you can complete your research within the confines of the assignment's due date, talk to your professor.
- Cultural and other type of bias -- we all have biases, whether we are conscience of them or not. Bias is when a person, place, or thing is viewed or shown in a consistently inaccurate way. Bias is usually negative, though one can have a positive bias as well, especially if that bias reflects your reliance on research that only support for your hypothesis. When proof-reading your paper, be especially critical in reviewing how you have stated a problem, selected the data to be studied, what may have been omitted, the manner in which you have ordered events, people, or places, how you have chosen to represent a person, place, or thing, to name a phenomenon, or to use possible words with a positive or negative connotation.
NOTE: If you detect bias in prior research, it must be acknowledged and you should explain what measures were taken to avoid perpetuating that bias.
- Fluency in a language -- if your research focuses on measuring the perceived value of after-school tutoring among Mexican-American ESL [English as a Second Language] students, for example, and you are not fluent in Spanish, you are limited in being able to read and interpret Spanish language research studies on the topic. This deficiency should be acknowledged.

Structure and Writing Style
Information about the limitations of your study are generally placed either at the beginning of the discussion section of your paper so the reader knows and understands the limitations before reading the rest of your analysis of the findings, or, the limitations are outlined at the conclusion of the discussion section as an acknowledgement of the need for further study. Statements about a study's limitations should not be buried in the body [middle] of the discussion section unless a limitation is specific to something covered in that part of the paper. If this is the case, though, the limitation should be reiterated at the conclusion of the section. If you determine that your study is seriously flawed due to important limitations, such as, an inability to acquire critical data, consider reframing it as an exploratory study intended to lay the groundwork for a more complete research study in the future. Be sure, though, to specifically explain the ways that these flaws can be successfully overcome in a new study. But, do not use this as an excuse for not developing a thorough research paper! Review the tab in this guide for developing a research topic. If serious limitations exist, it generally indicates a likelihood that your research problem is too narrowly defined or that the issue or event under study is too recent and, thus, very little research has been written about it. If serious limitations do emerge, consult with your professor about possible ways to overcome them or how to revise your study. When discussing the limitations of your research, be sure to: Describe each limitation in detailed but concise terms; Explain why each limitation exists; Provide the reasons why each limitation could not be overcome using the method(s) chosen to acquire or gather the data [cite to other studies that had similar problems when possible]; Assess the impact of each limitation in relation to the overall findings and conclusions of your study; and, If appropriate, describe how these limitations could point to the need for further research. Remember that the method you chose may be the source of a significant limitation that has emerged during your interpretation of the results [for example, you didn't interview a group of people that you later wish you had]. If this is the case, don't panic. Acknowledge it, and explain how applying a different or more robust methodology might address the research problem more effectively in a future study. A underlying goal of scholarly research is not only to show what works, but to demonstrate what doesn't work or what needs further clarification. Aguinis, Hermam and Jeffrey R.

Limitations of a Study: The Complete Guide
Research limitations make most studies imperfect. At its core, the research aims to investigate a specific question or questions about a topic. However, some things can hinder your ability to investigate the question or questions extensively. While this can make achieving your goals challenging, it enables you to point areas that require further studies.
That’s why you should demonstrate how future studies can provide answers to your unanswered questions if you encounter study limitations that affect your findings. Presenting the limitations of a study properly shows the readers that you understand your research problem.
After presenting your research findings, your assessment committee wants to see that you did your work professionally. And presenting limitations in a study shows that you carefully thought about your study problem and performed a review of the available literature while analyzing your preferred methods.
What Are Limitations in Research?
Well, limitations mean anything that might affect the generalizability or reliability of the outcomes of an experiment or a study. And this can relate to research design, like your approach or methods. It can also be something to do with how you carried out your research, like running out of resources or time before completing the study.
Either way, students should include their limitations when writing up their studies. In most cases, researchers include limitations in their analysis and discussions. But different schools can provide varying guidelines on how to include limitations in a research paper. Therefore, seek advice from your educator or check your writing style guide to know where to include the limitations of a study when writing a dissertation.
Common Study Limitations
Each study can have unique limitations. However, most students encounter common study limitations when writing academic papers. Here are some of the most common limitations you’re likely to encounter when writing your academic papers.
Sample profile or size: Most researchers encounter sampling as a limitation for their studies. That’s because they have difficulties finding the right sample with the necessary characteristics and size parameters. And this hinders the generalizability of their study results. Also, different sampling techniques are prone to bias and errors. And this can influence the study outcomes. In some cases, researchers have difficulties selecting their samples and opt to pick their participants selectively. Some researchers can even include irrelevant subjects in their general pool to hit their preferred sample size. Availability of previous research or information: Theoretical concepts or previous knowledge form the basis of studies on specific topics. And this provides a sound foundation on which a researcher can develop a research problem for their investigation and a design. However, a topic can be relatively specific or very progressive. In that case, the lack of or inadequate knowledge and previous studies can limit the analysis scope. And this can cause inaccuracies in the arguments or present a significant error margin in several methodologies and research aspects. Methodology errors: Modern research complexity can cause potential methodology limitations. In most cases, these research limitations relate to how the researchers collect and analyze data. That’s because these aspects can influence the outcomes of a study. Researchers use different techniques to gather data. While these techniques may suit a study design, they can present limitations in terms of inappropriate detail levels, distractions, and privacy. Bias: Bias is a potential limitation whose effects can influence the outcome of every study. However, a researcher can avoid this limitation by eliminating prejudiced or emotional attitudes towards their topic and conflict of interest. Researchers should also establish an oversight level by referring to peer-review procedures or an ethics committee. Bias is an inherent trait for human beings. Even the most objective people exhibit a bias to some extent. Nevertheless, a researcher should remain objective while trying to control potential inaccuracies or bias during the research process.
A researcher may not have control over the limitation of study. However, the limitation can be the condition, influence, or shortcoming that places restrictions on their conclusions or methodology. Therefore, researchers should mention all limitations that can influence their results.
Limitations of the Study Example
The purpose of most studies is to confirm or establish facts, reaffirm a previous study’s outcomes, solve current or new issues, develop a new theory, or support theorems. Research should also enable experts to develop knowledge on specific subjects. And people research different subjects, depending on their interests. However, researchers experience limitations of quantitative research and qualitative research. Here are the most common limitations in research.
Lack or inadequate interactions: Researchers might lack adequate interactions with government institutions and businesses. Consequently, they do not tap a substantial data amount. Researchers should arrange interaction programs with other establishments. That way, they can identify issues that warrant investigation and the necessary data for conducting research, as well as, the benefits of their studies. Overlapping studies can lead fritter resources away or duplicate the findings. Appropriate revision and compilation at regular intervals can solve this problem. Costly publishing: After researching a topic, a researcher should find ways to publish their findings. However, international journals cost a lot of money to publish a study. And this can discourage a researcher from publishing their work. For instance, a study involving females only or carried out in a specific town can have limitations like sample size, gender, and location. What’s more, the entire study could be limited to the researcher’s perception. Lack of or inadequate training: The research process doesn’t have a systematic methodology. Many researchers do not understand the research method when carrying out their work. Consequently, most researchers experience methodological limitations. Essentially, most researchers replicate the methodologies of similar studies. Even some research guides don’t explain the methodologies accurately. And this can limit the outcome of some studies. Lack of code of conduct: Researchers don’t have a code of conduct. And this causes inter-university and inter-departmental rivalries. Library functioning and management are not adequate in most places. Consequently, some researchers spend a lot of energy and time tracing the necessary books, reports, and journals for their studies. Such energy and time can be spent tracing relevant materials. Lack of confidence: The lack of confidence is among the most common limitations of research studies because company managers think that a researcher can misuse the data they disclose to them. Consequently, they don’t want to reveal their business information. And this can affect studies, yet data from researchers can help the same institutions. Therefore, organizations and researchers should implement confidence-building strategies to encourage companies to share data, knowing that researchers will use it productively.
Why Write the Limitations of a Study?
When writing a research paper or a thesis, some people think including study limitations is counterintuitive. That’s particularly the case for researchers that experienced something wrong. However, mentioning the limitations of your study is imperative for the following reasons.
- It tells the readers that you understand that no study lacks some limitations, and you took the time to analyze your work critically.
- It provides opportunities for further studies.
- It enables you to discuss the impacts of the limitations on your analysis and how future studies can address the challenges you encountered if granted a chance to do the study again.
- It presents your study as a transparent undertaking, making the results useful and credible for other people.
Most professors spot problems with the students’ work even if they don’t mention them. Consequently, embracing the limitations of your study and including them in your analysis is the best approach. Leaving out the limitations of research or vital aspects of a study can be detrimental to the entire study field. That’s because it can establish a potentially fallacious and incomplete depiction of the study.
In the academic world, players expect researchers to include the limitations of their works. And this includes a section that demonstrates a holistic and comprehensive understanding of a topic and research process by the author. Discussing limitations is a learning process for assessing the magnitude while critically evaluating the extenuating effect of the stated limitations.
Stating the limitations of a study also improves the validity and quality of future studies. And this includes limitations whose basis is the transparency principle in scientific research, whose purpose is to promote further progress while maintaining mutual integrity in similar studies.
How to Write Study Limitations
When writing your research limitations, do it in a way that demonstrates your understanding of the core concepts of confounding, analytical self-criticism, and bias. Highlighting every limitation might not be necessary. However, include every limitation with a direct impact on your research problem or study results.
Present your thought process as a researcher and explain the pros and cons of your decisions. Also, explain circumstances that may have led to a research limitation. Here’s how you should structure your limitations.
- Identification and description of the limitation: Use professional terminology to identify and describe the limitation. Also, include all necessary accompanying definitions. The limitation explanation should be precise and brief to ensure that the audience can easily understand the issue. Additionally, make sure that your audience can follow your thought pattern.
- Outline the possible impact or influence of the limitation: Explain to your readers how the limitation may have affected or influenced your study. And this comprises elements like the impact’s magnitude, occurrence likelihood, and the general direction the specific limitation could have driven your findings. Researchers generally accept that a limitation can have a more profound influence on a study than others. Therefore, highlight the effect or influence of a limitation to help readers decide on the issues to consider while examining your topic. And this is vital because a limitation whose value bias is null is less dangerous.
- Discuss alternative approaches to limitations: You can also discuss alternative ways to approach the limitations of your research question. However, the researcher should support the methodology or approach they selected in their study. Also, a research paper should explain why the study context warranted the methodology or approach, regardless of the limitation’s nature. Some researchers even provide persuasive evidence while discussing alternative decisions to some extent. And this shows thought transparency while reassuring readers that the researcher chose the best approach, despite the possible laminations.
- Description of the techniques for minimizing risks: Any limitation in research comes with some risks. Therefore, a researcher should describe possible techniques for minimizing the potential risk from the stated limitations. Such techniques can include a reference of previous studies and suggestions for improving data analysis and research design.
Don’t forget that acknowledging your study limitations provides a chance to suggest the direction for further studies. Therefore, connect the limitations of your study to the suggestions you make for further research. Also, explain how your study can make the unanswered questions more focused.
Also, acknowledging the limitation of the study enables you to demonstrate to the professor that you have critically thought about your research problem and understood the importance of the already-published literature. What’s more, it shows that you’ve carefully assessed the methods for studying your study problem. In research, a key objective is to discover new knowledge while confronting assumptions as you explore what others might not know.
Writing limitations should be a subjective process. That’s because you must analyze the impacts of the limitations and include them in your paper. In this section, don’t include the key weaknesses only. Instead, highlight the magnitude of the limitations of your research. And doing this requires you to demonstrate your study’s validity. Show the readers how the limitations have impacted your study outcomes and conclusions. Thus, writing the limitations section of your paper requires an overall, critical interpretation and appraisal of the impact. Essentially, this section should tell the readers why the problems with methods, errors, validity, and other limitations matter and to what extent.
Practical Tips for Writing Research Limitations
When writing a research paper, include information about your study’s limitations at the beginning of the discussion section. That way, your readers can understand your study limitations before delving into the deeper analysis. In some cases, authors bring out limitations when concluding their research discussion and highlighting the essence of further study on the subject. Here are practical tips to help you write the limitations of your study more effectively.
- Check some examples of limitations in research first: To understand the best way to include or present the limitations of your study, check how other authors do it. The internet is awash with good sample papers with a section for limitations. Checking such samples can help you write a limitations section for your academic paper.
- Include essential limitations only: Don’t come up with a list of limitations in your research paper. That’s because doing so can discredit the entire research project. Instead, highlight up to 3 limitations whose influence on your work was the highest. Also, explain how each of the limitations affected your work and research findings.
- Be brief and direct to the point: Identify the limitation, what caused it, and its impact on your research. Don’t expound on the limitation beyond this because the limitation section should be a small part of your paper.
- Be sincere: Don’t make up some lies or disguise your research limitations. That’s because doing so could prove you aren’t prepared. Therefore, be true and sincere with the audience. As you might see in good examples of study limitations, this section tells the audience what could be different or better.
- Explain what caused the limitations of your study: Your audience should have an easy time identifying the reason for the limitations. Therefore, make sure that you have explained everything correctly. Telling the readers about a limiting factor without explaining it can give them the impression that you’re outside your research project.
- Make suggestions for further studies: An ideal way for reversing points that other researchers can explore is to suggest future research paths. Your study could have failed in certain aspects. Maybe you didn’t achieve your expected results. However, it can prompt other researchers to take different directions in their future studies. Also, explain how other researchers can overcome the limitations you encountered in your study. You can even demonstrate why additional studies on the topic or subject are essential.
- Don’t confuse negative results with limitations: If your study brings out negative results, don’t confuse them for limitations. What negative outcomes mean is that you should support your hypothesis instead of opposing it. Perhaps, you can check sample limitations to understand what qualifies as a limitation. However, you can reformulate your hypothesis if you get negative results. Even when you stumble onto something you didn’t expect, don’t highlight it as a limitation.
Final Thoughts
When working on the limitations section of a research paper, be precise and clear. If writing this section becomes challenging, follow the tips shared in this article or seek assistance. That way, you can impress your educator by highlighting the limitations of your study properly.

Research Limitations
It is for sure that your research will have some limitations and it is normal. However, it is critically important for you to be striving to minimize the range of scope of limitations throughout the research process. Also, you need to provide the acknowledgement of your research limitations in conclusions chapter honestly.
It is always better to identify and acknowledge shortcomings of your work, rather than to leave them pointed out to your by your dissertation assessor. While discussing your research limitations, don’t just provide the list and description of shortcomings of your work. It is also important for you to explain how these limitations have impacted your research findings.
Your research may have multiple limitations, but you need to discuss only those limitations that directly relate to your research problems. For example, if conducting a meta-analysis of the secondary data has not been stated as your research objective, no need to mention it as your research limitation.
Research limitations in a typical dissertation may relate to the following points:
1. Formulation of research aims and objectives . You might have formulated research aims and objectives too broadly. You can specify in which ways the formulation of research aims and objectives could be narrowed so that the level of focus of the study could be increased.
2. Implementation of data collection method . Because you do not have an extensive experience in primary data collection (otherwise you would not be reading this book), there is a great chance that the nature of implementation of data collection method is flawed.
3. Sample size. Sample size depends on the nature of the research problem. If sample size is too small, statistical tests would not be able to identify significant relationships within data set. You can state that basing your study in larger sample size could have generated more accurate results. The importance of sample size is greater in quantitative studies compared to qualitative studies.
4. Lack of previous studies in the research area . Literature review is an important part of any research, because it helps to identify the scope of works that have been done so far in research area. Literature review findings are used as the foundation for the researcher to be built upon to achieve her research objectives.
However, there may be little, if any, prior research on your topic if you have focused on the most contemporary and evolving research problem or too narrow research problem. For example, if you have chosen to explore the role of Bitcoins as the future currency, you may not be able to find tons of scholarly paper addressing the research problem, because Bitcoins are only a recent phenomenon.
5. Scope of discussions . You can include this point as a limitation of your research regardless of the choice of the research area. Because (most likely) you don’t have many years of experience of conducing researches and producing academic papers of such a large size individually, the scope and depth of discussions in your paper is compromised in many levels compared to the works of experienced scholars.
You can discuss certain points from your research limitations as the suggestion for further research at conclusions chapter of your dissertation.

Turning a research limitation or future research suggestion into a potential topic idea
As our article, Our top tip for finding a dissertation topic highlighted, the Limitations and Future Research section of journal articles are arguably the quickest and easiest way to find a possible dissertation topic at the undergraduate and master's level. After all, in this section of academic journals, researchers explain the limitations of their own research, as well as potential new lines of inquiry that other researchers could explore. However, the trick is to know how to take the research limitations and/or future research suggestions in these journal articles and turn them into a potential topic idea for your dissertation. In this article, we explain how to achieve this.
Knowing how to turn a research limitation or future research suggestion into a potential dissertation topic is simply a matter of following a few steps. Since these steps are slightly different depending on whether you are creating a topic idea from a research limitation or a future research suggestion, we have divided this article into two parts:
Using research limitations as a basis to come up with a dissertation topic idea
Using future research suggestions as a basis to come up with a dissertation topic idea
To use research limitations as a basis to come up with a dissertation topic idea, you first need to have read a journal article on a topic that interests you. Having read this journal article, focus on the section at the end of the article, often called Research Limitations (or Discussion/Future Research ), where the authors criticise their own work. Now, follow the four steps below:
- STEP ONE: Identify the types of research limitation discussed by the authors
- STEP TWO: Understand the potential relationship between these research limitations and what makes a dissertation topic significant
- STEP THREE: Choose a research limitation that interests you
- STEP FOUR: Turn your dissertation topic idea into a purpose statement
STEP ONE Identify the types of research limitation discussed by the authors
Authors of good journal articles will highlight a number of limitations in their work. These include:
An inability to answer your research questions
Theoretical and conceptual problems
Limitations of your research strategy
Problems of research quality
Within the Research Limitations section, we go into more detail on each of these types of research limitation. Reading these articles will help you to identify what types of research limitation are being discussed by the authors in the journal article you are interested in.
STEP TWO Understand the potential relationship between these research limitations and what makes a dissertation topic significant
Whilst dissertations are rarely "ground-breaking" at the undergraduate or master's level (and are not expected to be), they should still be significant in some way. When coming up with a dissertation topic idea, you need to be able to explain how your idea is significant . Your research may be significant in one or a number of ways. It may:
Capitalise on a recent event
Reflect a break from the past
Target a new audience
Address a flaw in a previous study
Expand a particular field of study
Help an individual, group, organisation, or community
Since this section of the article deals with using research limitations as a basis for coming up with a dissertation topic idea, just two of these perspectives on research significance are relevant: (a) the ability to address a flaw in a previous study ; and (b) the desire to reflect a break from the past . Let's take each in turn:
The ability to address a flaw in a previous study
The journal article you are reading may have: (a) a flaw that the authors identified after the research was completed; and/or (b) a flaw that they had not anticipated in the first instance. When we use the word flaw , we do not mean that the limitation is necessarily disastrous to the study that was carried out. We use the word loosely to highlight that any academic reviewing the journal article you were interested in could identify a particular factor as a limitation.
A flaw identified after the research was completed
When you complete a piece of research, it is easy to look back and recognise flaws. A common problem is the inability to collect sufficient data and/or information. Sometimes this is because your sample size was too small .
For example, imagine you were interested in the career choices of university students at a university with 20,000 students (your population ). You hoped to interview (or survey, observe etc.) 100 people (your sample ), but in the end you only managed to get 30 people to take part in your research. As a result, you are no longer sure whether you collected sufficient data and/or information to answer your research questions with confidence. In other words, you are not sure whether your smaller sample of just 30 people adequately reflects the population of 20,000 students you were interested in studying. Limitations like this are very common.
A flaw that was not anticipated in the first instance
Sometimes researchers use the Research Limitations section of a journal article to reflect on a flaw that they did not anticipate in the first instance. These kinds of flaws may become evident during the research process when the data is being collected and/or analysed. This makes it much more difficult to anticipate such flaws in the first place.
For example, imagine that you had used a survey to examine the career choices of students at a university of 20,000 students (discussed above). For the most part, the survey contained closed questions . These are questions where the potential response to a question is pre-determined (see the example below):
Question What factors influence your choice of career?
Options [tick all that apply] Career prospects Nature of the work Physical working conditions Salary and benefits Other If Other , please state what this is..........
Let's assume that these potential responses are based on your reading of the literature on career choices. However, since we do not want to miss out any options that we have not thought about or that are not in the literature, we include an open question , labelled Other . Respondents can write anything in the space provided.
When we analyse our data, we find that career prospects and salary and benefits were the main factors influencing career choices amongst the university students. However, we also see that a large proportion of respondents had entered factors into the Other option. The idea that people wanted flexible working arrangements was mentioned by most of these respondents. Whilst today we should have included this option in the survey (i.e. flexible working) because it is often mentioned in the literature, if we went back 20 years, this would not have been the case. Therefore, imagining that we were doing this research 20 years ago, we may have missed out an important option in the initial data collection process. Since the literature had not focused on flexible working as an important factor influencing career choices at the time, such a flaw (i.e., missing out flexible working arrangements as an option in the survey) may not have been anticipated when creating the survey.
Whether the flaw you are trying to address was anticipated by the authors of the journal article you are interested in or not, the important point is that addressing such flaws in previous studies is a way that your research can be significant . It can help to justify your choice of dissertation topic.
The desire to reflect a break from the past
Breaking from the past simply means that you want your dissertation to adopt a different approach to the way that previous research was conducted.
The journal article that you are reading will have followed a particular research strategy . The choice of research strategy adopted by the authors is important because it guides the entire dissertation process, from the choice of research design , research methods , data analysis techniques , and so forth [see the section on Research Strategy for an introduction to these components of research strategy]. Since the choice of research strategy is so important in guiding the dissertation process, breaking away from the research strategy adopted by the authors of the journal article you are interested in can make your dissertation significant .
To illustrate this point, let's reflect on the example we just used where we were interested in examining the career choices of students at a university of 20,000 students. This study was guided by a quantitative research design and the use of survey methods . Therefore, a survey was constructed based on the literature, which contained mostly closed questions . For example:
The potential flaw with the study was that potential options, such as flexible working arrangements had been missed out of the list of options . Such options had been missed out (i.e., not anticipated in the first instance) because they were not prominent in the literature. So the question arises: How can this potential flaw be addressed by breaking from the past ?
Let's imagine that instead of using a quantitative research design, we used a mixed methods research design instead. This would involve a combination of qualitative and quantitative research methods .
Rather than relying on the literature alone to come up with the list of options for our survey questions, we could have started the research process with interviews (i.e., a qualitative , primary research phase). By interviewing a sample of the students at the university, we could have first found out all (or most of ) the factors that students thought about when being asked: What factors influence your choice of career? This would ensure that our list of options to be included for this survey question was more comprehensive . The options that were included would not have only been based on a review of the literature on career choices, but also a qualitative , primary research phase.
By using a mixed methods research design instead of a quantitative research design, you could have highlighted how (a) your dissertation broke from the past and (b) why it was significant as a result of this.
Moving forward...
So you need to look at the journal article you are interested in, identify all of the types of flaws in the Limitations and Future Research section, and then try and identify how these research limitations and aspects of research significance are connected in some way. For example, if the authors stated that they had a low response rate , this may indicate that their sample size was too small (or at least lower than they had hoped for). If this was the case, and the authors suggested that this was a major problem (or you feel it could have been a major problem), you could argue that addressing this flaw is one way in which your dissertation topic could be significant . Taking the second example that was presented, if the authors of the journal article you were interested in highlighted problems that could be associated with their choice of research design (e.g., quantitative vs. mixed methods research design), this could illustrate the significance of a study addressing this particular flaw in research design.

How to Write a Discussion Section | Tips & Examples
Published on August 21, 2022 by Shona McCombes . Revised on July 18, 2023.
The discussion section is where you delve into the meaning, importance, and relevance of your results .
It should focus on explaining and evaluating what you found, showing how it relates to your literature review and paper or dissertation topic , and making an argument in support of your overall conclusion. It should not be a second results section.
There are different ways to write this section, but you can focus your writing around these key elements:
- Summary : A brief recap of your key results
- Interpretations: What do your results mean?
- Implications: Why do your results matter?
- Limitations: What can’t your results tell us?
- Recommendations: Avenues for further studies or analyses

What not to include in your discussion section, step 1: summarize your key findings, step 2: give your interpretations, step 3: discuss the implications, step 4: acknowledge the limitations, step 5: share your recommendations, discussion section example, other interesting articles, frequently asked questions about discussion sections.
There are a few common mistakes to avoid when writing the discussion section of your paper.
- Don’t introduce new results: You should only discuss the data that you have already reported in your results section .
- Don’t make inflated claims: Avoid overinterpretation and speculation that isn’t directly supported by your data.
- Don’t undermine your research: The discussion of limitations should aim to strengthen your credibility, not emphasize weaknesses or failures.

- Missing reference entries
Start this section by reiterating your research problem and concisely summarizing your major findings. To speed up the process you can use a summarizer to quickly get an overview of all important findings. Don’t just repeat all the data you have already reported—aim for a clear statement of the overall result that directly answers your main research question . This should be no more than one paragraph.
Many students struggle with the differences between a discussion section and a results section . The crux of the matter is that your results sections should present your results, and your discussion section should subjectively evaluate them. Try not to blend elements of these two sections, in order to keep your paper sharp.
- The results indicate that…
- The study demonstrates a correlation between…
- This analysis supports the theory that…
- The data suggest that…
The meaning of your results may seem obvious to you, but it’s important to spell out their significance for your reader, showing exactly how they answer your research question.
The form of your interpretations will depend on the type of research, but some typical approaches to interpreting the data include:
- Identifying correlations , patterns, and relationships among the data
- Discussing whether the results met your expectations or supported your hypotheses
- Contextualizing your findings within previous research and theory
- Explaining unexpected results and evaluating their significance
- Considering possible alternative explanations and making an argument for your position
You can organize your discussion around key themes, hypotheses, or research questions, following the same structure as your results section. Alternatively, you can also begin by highlighting the most significant or unexpected results.
- In line with the hypothesis…
- Contrary to the hypothesized association…
- The results contradict the claims of Smith (2022) that…
- The results might suggest that x . However, based on the findings of similar studies, a more plausible explanation is y .
As well as giving your own interpretations, make sure to relate your results back to the scholarly work that you surveyed in the literature review . The discussion should show how your findings fit with existing knowledge, what new insights they contribute, and what consequences they have for theory or practice.
Ask yourself these questions:
- Do your results support or challenge existing theories? If they support existing theories, what new information do they contribute? If they challenge existing theories, why do you think that is?
- Are there any practical implications?
Your overall aim is to show the reader exactly what your research has contributed, and why they should care.
- These results build on existing evidence of…
- The results do not fit with the theory that…
- The experiment provides a new insight into the relationship between…
- These results should be taken into account when considering how to…
- The data contribute a clearer understanding of…
- While previous research has focused on x , these results demonstrate that y .

Even the best research has its limitations. Acknowledging these is important to demonstrate your credibility. Limitations aren’t about listing your errors, but about providing an accurate picture of what can and cannot be concluded from your study.
Limitations might be due to your overall research design, specific methodological choices , or unanticipated obstacles that emerged during your research process.
Here are a few common possibilities:
- If your sample size was small or limited to a specific group of people, explain how generalizability is limited.
- If you encountered problems when gathering or analyzing data, explain how these influenced the results.
- If there are potential confounding variables that you were unable to control, acknowledge the effect these may have had.
After noting the limitations, you can reiterate why the results are nonetheless valid for the purpose of answering your research question.
- The generalizability of the results is limited by…
- The reliability of these data is impacted by…
- Due to the lack of data on x , the results cannot confirm…
- The methodological choices were constrained by…
- It is beyond the scope of this study to…
Based on the discussion of your results, you can make recommendations for practical implementation or further research. Sometimes, the recommendations are saved for the conclusion .
Suggestions for further research can lead directly from the limitations. Don’t just state that more studies should be done—give concrete ideas for how future work can build on areas that your own research was unable to address.
- Further research is needed to establish…
- Future studies should take into account…
- Avenues for future research include…

In the discussion , you explore the meaning and relevance of your research results , explaining how they fit with existing research and theory. Discuss:
- Your interpretations : what do the results tell us?
- The implications : why do the results matter?
- The limitation s : what can’t the results tell us?
The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.
In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.
In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.
The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

The purpose of the discussion section is to interpret and describe the significance of your findings in relation to what was already known about the research problem being investigated and to explain any new understanding or insights that emerged as a result of your research. The discussion will always connect to the introduction by way of the research questions or hypotheses you posed and the literature you reviewed, but the discussion does not simply repeat or rearrange the first parts of your paper; the discussion clearly explains how your study advanced the reader's understanding of the research problem from where you left them at the end of your review of prior research.

Importance of a Good Discussion
The discussion section is often considered the most important part of your research paper because it:
- Most effectively demonstrates your ability as a researcher to think critically about an issue, to develop creative solutions to problems based upon a logical synthesis of the findings, and to formulate a deeper, more profound understanding of the research problem under investigation;
- Presents the underlying meaning of your research, notes possible implications in other areas of study, and explores possible improvements that can be made in order to further develop the concerns of your research;
- Highlights the importance of your study and how it can contribute to understanding the research problem within the field of study;
- Presents how the findings from your study revealed and helped fill gaps in the literature that had not been previously exposed or adequately described; and,
- Engages the reader in thinking critically about issues based on an evidence-based interpretation of findings; it is not governed strictly by objective reporting of information.

Fourteen Steps to Writing an Effective Discussion Section. San Francisco Edit, 2003-2008.
Structure and Writing Style
I. General Rules
These are the general rules you should adopt when composing your discussion of the results :
- Do not be verbose or repetitive; be concise and make your points clearly
- Avoid the use of jargon or undefined technical language
- Follow a logical stream of thought; in general, interpret and discuss the significance of your findings in the same sequence you described them in your results section [a notable exception is to begin by highlighting an unexpected result or a finding that can grab the reader's attention]
- Use the present verb tense, especially for established facts; however, refer to specific works or prior studies in the past tense
- If needed, use subheadings to help organize your discussion or to categorize your interpretations into themes
II. The Content
The content of the discussion section of your paper most often includes :
- Explanation of results : Comment on whether or not the results were expected for each set of findings; go into greater depth to explain findings that were unexpected or especially profound. If appropriate, note any unusual or unanticipated patterns or trends that emerged from your results and explain their meaning in relation to the research problem.
- References to previous research : Either compare your results with the findings from other studies or use the studies to support a claim. This can include re-visiting key sources already cited in your literature review section, or, save them to cite later in the discussion section if they are more important to compare with your results instead of being a part of the general literature review of prior research used to provide context and background information. Note that you can make this decision to highlight specific studies after you have begun writing the discussion section.
- Deduction : A claim for how the results can be applied more generally. For example, describing lessons learned, proposing recommendations that can help improve a situation, or highlighting best practices.
- Hypothesis : A more general claim or possible conclusion arising from the results [which may be proved or disproved in subsequent research]. This can be framed as new research questions that emerged as a consequence of your analysis.
III. Organization and Structure
Keep the following sequential points in mind as you organize and write the discussion section of your paper:
- Think of your discussion as an inverted pyramid. Organize the discussion from the general to the specific, linking your findings to the literature, then to theory, then to practice [if appropriate].
- Use the same key terms, narrative style, and verb tense [present] that you used when describing the research problem in your introduction.
- Begin by briefly re-stating the research problem you were investigating and answer all of the research questions underpinning the problem that you posed in the introduction.
- Describe the patterns, principles, and relationships shown by each major findings and place them in proper perspective. The sequence of this information is important; first state the answer, then the relevant results, then cite the work of others. If appropriate, refer the reader to a figure or table to help enhance the interpretation of the data [either within the text or as an appendix].
- Regardless of where it's mentioned, a good discussion section includes analysis of any unexpected findings. This part of the discussion should begin with a description of the unanticipated finding, followed by a brief interpretation as to why you believe it appeared and, if necessary, its possible significance in relation to the overall study. If more than one unexpected finding emerged during the study, describe each of them in the order they appeared as you gathered or analyzed the data. As noted, the exception to discussing findings in the same order you described them in the results section would be to begin by highlighting the implications of a particularly unexpected or significant finding that emerged from the study, followed by a discussion of the remaining findings.
- Before concluding the discussion, identify potential limitations and weaknesses if you do not plan to do so in the conclusion of the paper. Comment on their relative importance in relation to your overall interpretation of the results and, if necessary, note how they may affect the validity of your findings. Avoid using an apologetic tone; however, be honest and self-critical [e.g., in retrospect, had you included a particular question in a survey instrument, additional data could have been revealed].
- The discussion section should end with a concise summary of the principal implications of the findings regardless of their significance. Give a brief explanation about why you believe the findings and conclusions of your study are important and how they support broader knowledge or understanding of the research problem. This can be followed by any recommendations for further research. However, do not offer recommendations which could have been easily addressed within the study. This would demonstrate to the reader that you have inadequately examined and interpreted the data.
IV. Overall Objectives
The objectives of your discussion section should include the following: I. Reiterate the Research Problem/State the Major Findings
Briefly reiterate the research problem or problems you are investigating and the methods you used to investigate them, then move quickly to describe the major findings of the study. You should write a direct, declarative, and succinct proclamation of the study results, usually in one paragraph.
II. Explain the Meaning of the Findings and Why They are Important
No one has thought as long and hard about your study as you have. Systematically explain the underlying meaning of your findings and state why you believe they are significant. After reading the discussion section, you want the reader to think critically about the results and why they are important. You don’t want to force the reader to go through the paper multiple times to figure out what it all means. If applicable, begin this part of the section by repeating what you consider to be your most significant or unanticipated finding first, then systematically review each finding. Otherwise, follow the general order you reported the findings presented in the results section.
III. Relate the Findings to Similar Studies
No study in the social sciences is so novel or possesses such a restricted focus that it has absolutely no relation to previously published research. The discussion section should relate your results to those found in other studies, particularly if questions raised from prior studies served as the motivation for your research. This is important because comparing and contrasting the findings of other studies helps to support the overall importance of your results and it highlights how and in what ways your study differs from other research about the topic. Note that any significant or unanticipated finding is often because there was no prior research to indicate the finding could occur. If there is prior research to indicate this, you need to explain why it was significant or unanticipated. IV. Consider Alternative Explanations of the Findings
It is important to remember that the purpose of research in the social sciences is to discover and not to prove . When writing the discussion section, you should carefully consider all possible explanations for the study results, rather than just those that fit your hypothesis or prior assumptions and biases. This is especially important when describing the discovery of significant or unanticipated findings.
V. Acknowledge the Study’s Limitations
It is far better for you to identify and acknowledge your study’s limitations than to have them pointed out by your professor! Note any unanswered questions or issues your study could not address and describe the generalizability of your results to other situations. If a limitation is applicable to the method chosen to gather information, then describe in detail the problems you encountered and why. VI. Make Suggestions for Further Research
You may choose to conclude the discussion section by making suggestions for further research [as opposed to offering suggestions in the conclusion of your paper]. Although your study can offer important insights about the research problem, this is where you can address other questions related to the problem that remain unanswered or highlight hidden issues that were revealed as a result of conducting your research. You should frame your suggestions by linking the need for further research to the limitations of your study [e.g., in future studies, the survey instrument should include more questions that ask..."] or linking to critical issues revealed from the data that were not considered initially in your research.
NOTE: Besides the literature review section, the preponderance of references to sources is usually found in the discussion section . A few historical references may be helpful for perspective, but most of the references should be relatively recent and included to aid in the interpretation of your results, to support the significance of a finding, and/or to place a finding within a particular context. If a study that you cited does not support your findings, don't ignore it--clearly explain why your research findings differ from theirs.
V. Problems to Avoid
- Do not waste time restating your results . Should you need to remind the reader of a finding to be discussed, use "bridge sentences" that relate the result to the interpretation. An example would be: “In the case of determining available housing to single women with children in rural areas of Texas, the findings suggest that access to good schools is important...," then move on to further explaining this finding and its implications.
- As noted, recommendations for further research can be included in either the discussion or conclusion of your paper, but do not repeat your recommendations in the both sections. Think about the overall narrative flow of your paper to determine where best to locate this information. However, if your findings raise a lot of new questions or issues, consider including suggestions for further research in the discussion section.
- Do not introduce new results in the discussion section. Be wary of mistaking the reiteration of a specific finding for an interpretation because it may confuse the reader. The description of findings [results section] and the interpretation of their significance [discussion section] should be distinct parts of your paper. If you choose to combine the results section and the discussion section into a single narrative, you must be clear in how you report the information discovered and your own interpretation of each finding. This approach is not recommended if you lack experience writing college-level research papers.
- Use of the first person pronoun is generally acceptable. Using first person singular pronouns can help emphasize a point or illustrate a contrasting finding. However, keep in mind that too much use of the first person can actually distract the reader from the main points [i.e., I know you're telling me this--just tell me!].

Writing Tip
Don’t Over-Interpret the Results!
Interpretation is a subjective exercise. As such, you should always approach the selection and interpretation of your findings introspectively and to think critically about the possibility of judgmental biases unintentionally entering into discussions about the significance of your work. With this in mind, be careful that you do not read more into the findings than can be supported by the evidence you have gathered. Remember that the data are the data: nothing more, nothing less.
MacCoun, Robert J. "Biases in the Interpretation and Use of Research Results." Annual Review of Psychology 49 (February 1998): 259-287; Ward, Paulet al, editors. The Oxford Handbook of Expertise . Oxford, UK: Oxford University Press, 2018.
Another Writing Tip
Don't Write Two Results Sections!
One of the most common mistakes that you can make when discussing the results of your study is to present a superficial interpretation of the findings that more or less re-states the results section of your paper. Obviously, you must refer to your results when discussing them, but focus on the interpretation of those results and their significance in relation to the research problem, not the data itself.
Azar, Beth. "Discussing Your Findings." American Psychological Association gradPSYCH Magazine (January 2006).
Yet Another Writing Tip
Avoid Unwarranted Speculation!
The discussion section should remain focused on the findings of your study. For example, if the purpose of your research was to measure the impact of foreign aid on increasing access to education among disadvantaged children in Bangladesh, it would not be appropriate to speculate about how your findings might apply to populations in other countries without drawing from existing studies to support your claim or if analysis of other countries was not a part of your original research design. If you feel compelled to speculate, do so in the form of describing possible implications or explaining possible impacts. Be certain that you clearly identify your comments as speculation or as a suggestion for where further research is needed. Sometimes your professor will encourage you to expand your discussion of the results in this way, while others don’t care what your opinion is beyond your effort to interpret the data in relation to the research problem.
