In Statistics, the determination of the variation between the group of data due to true variation is done by hypothesis testing. The sample data are taken from the population parameter based on the assumptions. The hypothesis can be classified into various types. In this article, let us discuss the hypothesis definition, various types of hypothesis and the significance of hypothesis testing, which are explained in detail.
In Statistics, a hypothesis is defined as a formal statement, which gives the explanation about the relationship between the two or more variables of the specified population. It helps the researcher to translate the given problem to a clear explanation for the outcome of the study. It clearly explains and predicts the expected outcome. It indicates the types of experimental design and directs the study of the research process.
The hypothesis can be broadly classified into different types. They are:
Simple Hypothesis
A simple hypothesis is a hypothesis that there exists a relationship between two variables. One is called a dependent variable, and the other is called an independent variable.
Complex Hypothesis
A complex hypothesis is used when there is a relationship between the existing variables. In this hypothesis, the dependent and independent variables are more than two.
Null Hypothesis
In the null hypothesis, there is no significant difference between the populations specified in the experiments, due to any experimental or sampling error. The null hypothesis is denoted by H 0 .
Alternative Hypothesis
In an alternative hypothesis, the simple observations are easily influenced by some random cause. It is denoted by the H a or H 1 .
Empirical Hypothesis
An empirical hypothesis is formed by the experiments and based on the evidence.
Statistical Hypothesis
In a statistical hypothesis, the statement should be logical or illogical, and the hypothesis is verified statistically.
Apart from these types of hypothesis, some other hypotheses are directional and non-directional hypothesis, associated hypothesis, casual hypothesis.
The important characteristics of the hypothesis are:

A psychologist reveals the meaning behind 2 common types of nightmares.
Ignoring the contents of your dreams might exacerbate your problems in waking life. Here's how you ... [+] can analyze your dreams to improve your waking hours.
We’ve all been there—waking up in a cold sweat, with your heart pounding after a nightmare so vivid, that it’s hard to remember what’s real. Whether it’s frantically running from a faceless pursuer, falling from a great height or being trapped in a room with no escape, these unsettling dreams can linger long after we’ve woken up.
While some dreams may be just our brain’s way of sorting through the day’s events, others, particularly nightmares, can be our mind’s way of working through real-life challenges and emotional conflicts.
Here are the meanings behind two common types of disturbing dreams, according to research on human consciousness.
In dreams of being chased, you might find yourself running away from an unknown figure, a threatening animal or even an intangible force. The sense of danger feels immediate, and no matter how fast you run, the pursuer seems to close in.
A study published this July in Frontiers In Psychology found that such dreams are associated with real-life experiences of having negative relationships with others.

Researchers suggest that this can be explained by the “ threat simulation theory ” of dreaming, according to which dreams serve an evolutionary function by simulating threatening events to practice and improve the mechanisms for real-life threat perception and avoidance. This helps individuals rehearse responses to potential dangers in a safe environment.
The emotional threat of conflict or dissatisfaction in real-life relationships can create a need to prepare for confrontation or further emotional upheaval. When individuals experience tension or discord in their social interactions, their mind may simulate scenarios of being chased as a way of processing these emotional threats. This not only allows them to rehearse responses to potential conflicts but also serves as a psychological tool to manage anxiety and stress related to those relationships.
Moreover, the theory suggests that such dreams aren’t just random occurrences but are deeply rooted in our ancestral need for survival. In the past, being chased could have signified real physical threats from predators or hostile individuals. In the modern world, these threats often manifest as social or emotional challenges, and the brain uses dreams to work through them.
Dreams of being suffocated are often intensely distressing. In these dreams, you might find yourself in situations where it becomes increasingly difficult to breathe, as if an invisible force is pressing down on your chest or throat.
Alternatively, you might be trapped in a small, enclosed space, like a coffin or a sealed room, where the air seems to grow thinner and thinner. Or, you might feel like you’re being held underwater, unable to reach the surface for air or that someone or something is physically covering your mouth and nose.
Interestingly, another study published in Frontiers in Psychology by a team of Israeli researchers shows that dreams of suffocation are associated with experiencing psychological distress in one’s waking life as well as general sleep disturbances.
Physiologically, those who experience respiratory issues during sleep, such as sleep apnea, or breathing problems in their waking life report dreams of suffocation more frequently than those without such issues. This suggests that the body’s struggle to breathe can manifest in dreams as the terrifying sensation of being smothered or choked.
Psychologically, those with anxiety or distress related to breathing—perhaps due to a fear of suffocation or choking—are also more likely to have these kinds of nightmares. Researchers suggest that the connection between psychological distress and suffocation dreams is further supported by the phenomenon of sleep paralysis.
During sleep paralysis, individuals often experience a terrifying sensation of being unable to move, sometimes coupled with hallucinations of a malevolent presence sitting on their chest, making it hard to breathe.
This eerie experience, which can feel like being smothered, is related to both physical sensations (like shallow breathing and body paralysis) and psychological factors (such as anxiety and stress).
So, understanding the deeper meanings behind our nightmares can offer valuable insights into our emotional, physical and psychological well-being. They serve as an important reminder that our body and mind are intricately connected.
If you find yourself frequently experiencing these types of nightmares, it is important to explore any unresolved conflicts or stressors in your waking life. By listening to these signals and taking proactive steps to address them, you can work towards more restful sleep and a greater sense of inner peace.

We asked nearly a dozen experts in sex and intimacy for the advice they repeat again and again. For starters, they said, don’t get so hung up on how often you have, or want, sex.
By Catherine Pearson
Couples worried about “mismatched” libidos. People struggling to orgasm. Lovers wondering if they’re having a “normal” amount of sex.
Sex therapists, educators and researchers tend to see these issues over and over again.
So Well reached out to several of them to ask: What do you wish more people knew about sex and intimacy?
Here’s what the experts had to say.
Lori Brotto, a psychologist and professor at the University of British Columbia who is the author of “Better Sex Through Mindfulness,” spends a lot of time trying to persuade people to discard the concept of a “normal” sex life when it comes to how and how often they get intimate.
The frequency with which couples have sex is not a meaningful measure of sexual health, she said, even though it is something “people get really hung up on.” It doesn’t tell you anything about whether individuals are actually enjoying time with their partners, and the sex they’re having, she added.
“I have worked with couples who are having sex every night and are miserable together,” echoed Casey Tanner, a sex therapist based in New York City and author of “Feel It All.” Conversely, she has worked with couples who feel deeply connected and who have sex maybe three times a year.
Let go of the numbers game, Ms. Tanner urged, and instead focus on how each sexual experience feels.

Nonimmigrants are foreign nationals admitted temporarily to the United States within classes of admission that are defined in section 101(a)(15) of the Immigration and Nationality Act (INA).
Examples of nonimmigrant classes of admission include foreign government officials, temporary visitors for business and pleasure, aliens in transit, treaty traders and investors, academic and vocational students, temporary workers, exchange visitors, athletes and entertainers, victims of certain crimes, and certain family members of U.S. citizens and lawful permanent residents (LPRs).
Unlike people granted LPR, or "green card" status, who may live in the United States essentially without restrictions, nonimmigrants are authorized to enter the country for specific purposes. Nonimmigrants’ duration of stay and lawful activities, such as employment, travel, and accompaniment by dependents, are prescribed by their class of admission.
Temporary worker visas are for persons who want to enter the United States for employment lasting a fixed period of time, and are not considered permanent or indefinite. To work in the United States temporarily as a lawful nonimmigrant, temporary workers must qualify for the available visa category based on the planned employment purpose. The steps in the process before applying for a visa vary.

Afghanistan’s Taliban government formally adopts a set of morality laws, including requiring women to cover their faces.
When the Taliban swept back into power three years ago, it took over a country in which the civil and political rights of Afghans were enshrined in the constitution.
But since then, many of those rights have been eroded – especially for women and girls.
Taliban celebrates three years of return to power in afghanistan, taliban ‘deliberately deprived’ 1.4 million girls of schooling: un, ‘an island of freedom’: inside the secret beauty salons of afghanistan.
Now, Taliban officials have published a new set of morality laws – which will in their words “promote virtue and prevent vice”.
The new laws in Afghanistan range from requiring women to cover their faces and men to grow beards to banning music in cars.
So, will this latest crackdown further isolate the Taliban?
And what impact will it have on the lives of millions of Afghans who are already struggling to survive?

"Providing educational interventions on healthy eating habits will result in weight loss in overweight individuals.".
A research hypothesis, in its plural form "hypotheses," is a specific, testable prediction about the anticipated results of a study, established at its outset. It is a key component of the scientific method. Hypotheses connect theory to data and guide the research process towards expanding scientific understanding.
Null Hypothesis. A hypothesis predicts the relationship between independent and dependent variables. An independent variable is something you change as part of an experiment such as the amount of water given to a plant. A dependent variable is something that is predicted to change as a result such as the growth rate of a plant.
5. Phrase your hypothesis in three ways. To identify the variables, you can write a simple prediction in if…then form. The first part of the sentence states the independent variable and the second part states the dependent variable.

A research hypothesis (also called a scientific hypothesis) is a statement about the expected outcome of a study (for example, a dissertation or thesis). To constitute a quality hypothesis, the statement needs to have three attributes - specificity, clarity and testability. Let's take a look at these more closely.
A research hypothesis helps test theories. A hypothesis plays a pivotal role in the scientific method by providing a basis for testing existing theories. For example, a hypothesis might test the predictive power of a psychological theory on human behavior. It serves as a great platform for investigation activities.
A hypothesis is a prediction of what will be found at the outcome of a research project and is typically focused on the relationship between two different variables studied in the research. It is usually based on both theoretical expectations about how things work and already existing scientific evidence. Within social science, a hypothesis can ...

A hypothesis (plural hypotheses) is a proposed explanation for an observation. The definition depends on the subject. In science, a hypothesis is part of the scientific method. It is a prediction or explanation that is tested by an experiment. Observations and experiments may disprove a scientific hypothesis, but can never entirely prove one.
The hypothesis of Andreas Cellarius, showing the planetary motions in eccentric and epicyclical orbits.

Hypothesis is a prediction of the outcome of a study. Hypotheses are drawn from theories and research questions or from direct observations. In fact, a research problem can be formulated as a hypothesis. To test the hypothesis we need to formulate it in terms that can actually be analysed with statistical tools.
