It is a specific, testable prediction about what you expect to happen in a study. For example, a study designed to look at the relationship between sleep deprivation and test performance might have a hypothesis that states, "This study is designed to assess the hypothesis that sleep-deprived people will perform worse on a test than individuals who are not sleep-deprived.

What is a hypothesis?

It is a specific, testable prediction about what you expect to happen in a study. For example, a study designed to look at the relationship between sleep deprivation and test performance might have a hypothesis that states, "This study is designed to assess the hypothesis that sleep-deprived people will perform worse on a test than individuals who are not sleep-deprived.

In the scientific method, whether it involves research in psychology, biology, or some other area, a hypothesis represents what the researchers think will happen in an experiment. The hypothesis is a prediction, but it involves more than a guess. Most of the time, the hypothesis begins with a question which is then explored through background research. It is only at this point that researchers begin to develop a testable hypothesis.

In a study exploring the effects of a particular drug, the hypothesis might be that researchers expect the drug to have some type of effect on the symptoms of a specific illness.

In psychology, the hypothesis might focus on how a certain aspect of the environment might influence a particular behavior. Remember, a hypothesis does not have to be correct. When conducting an experiment, researchers might explore a number of factors to determine which ones might contribute to the ultimate outcome. When writing up these results, the researchers might suggest other options that should be explored in future studies.

In many cases, researchers might draw a hypothesis from a specific theory or build on previous research. For example, prior research has shown that stress can impact the immune system. So a researcher might hypothesize: "People with high-stress levels will be more likely to contract a common cold after being exposed to the virus than people who have low-stress levels. In other instances, researchers might look at commonly held beliefs or folk wisdom.

The researcher might pose a specific hypothesis that "People tend to select romantic partners who are similar to them in interests and educational level. When trying to come up with a good hypothesis for your own research or experiments, ask yourself the following questions:. Before you come up with a specific hypothesis, spend some time doing background research. Once you have completed a literature review, start thinking about potential questions you still have.

Many authors will suggest questions that still need to be explored. In order to form a hypothesis, you should take these steps:. Students sometimes confuse the idea of falsifiability with the idea that it means that something is false, which is not the case. However, the researcher must also define how the variable will be manipulated and measured in the study.

A "study habits" variable might be defined by the amount of studying that actually occurs as measured by time. These precise descriptions are important because many things can be measured in a number of different ways. One of the basic principles of any type of scientific research is that the results must be replicable.

Some variables are more difficult than others to define. How would you operationally define a variable such as aggression? For obvious ethical reasons, researchers cannot create a situation in which a person behaves aggressively toward others. In order to measure this variable, the researcher must devise a measurement that assesses aggressive behavior without harming other people. In this situation, the researcher might utilize a simulated task to measure aggressiveness.

Once a researcher has formed a testable hypothesis, the next step is to select a research design and start collecting data. The research method depends largely on exactly what they are studying. There are two basic types of research methods: descriptive research and experimental research. This type of research method might be used to investigate a hypothesis that is difficult to test experimentally. In an experiment, the researcher systematically manipulates a variable of interest known as the independent variable and measures the effect on another variable known as the dependent variable.

The hypothesis is a critical part of any scientific exploration. It represents what researchers expect to find in a study or experiment. In situations where the hypothesis is unsupported by the research, the research still has value.

Such research helps us better understand how different aspects of the natural world relate to one another. It also helps us develop new hypotheses that can then be tested in the future. Ever wonder what your personality type means? Sign up to find out more in our Healthy Mind newsletter.

Hypotheses

A hypothesis is a stepping stone to a soon-to-be proven theory. For a hypothesis to be considered a scientific hypothesis, it must be proven through the scientific method. Like anything else in life, there are many paths to take to get to the same ending. Let's take a look at the different types of hypotheses that can be employed when seeking to prove a new theory. Before diving into hypothesis examples, you must take a moment to understand independent and dependent variables. Simply put, an independent variable is the cause, and the dependent variable is the effect.

Hypothesis A hypothesis is a tentative relationship between two or more variables which direct the research activity to test it. A hypothesis is a testable prediction which is expected to occur. It can be a false or a true statement that is tested in the research to check its authenticity. Sometimes, it is very difficult to start a research without having a valid foundation. Hence, the research builds a logical relationship between various phenomena to start working on the research. This logical relationship is relevant to the theme of the research.

An hypothesis is a specific statement of prediction. It describes in concrete rather than theoretical terms what you expect will happen in your study. Not all studies have hypotheses. Sometimes a study is designed to be exploratory see inductive research. There is no formal hypothesis, and perhaps the purpose of the study is to explore some area more thoroughly in order to develop some specific hypothesis or prediction that can be tested in future research. A single study may have one or many hypotheses. Actually, whenever I talk about an hypothesis, I am really thinking simultaneously about two hypotheses.


A hypothesis is a statement of the researcher's expectation or prediction about relationship among study variables. The research process begins and ends with the hypothesis. It is core to the entire procedure and, therefore, is of the utmost importance. Hypothesis is nothing but the heat of the research.

By Saul McLeod , updated August 10, A hypothesis plural hypotheses is a precise, testable statement of what the researcher s predict will be the outcome of the study. This usually involves proposing a possible relationship between two variables: the independent variable what the researcher changes and the dependent variable what the research measures. In research, there is a convention that the hypothesis is written in two forms, the null hypothesis, and the alternative hypothesis called the experimental hypothesis when the method of investigation is an experiment.

    In statistical hypothesis testing , the alternative hypothesis is a position that states something is happening, a new theory is preferred instead of an old one null hypothesis.
