If you are comparing two groups, the hypothesis can state what difference you expect to find between them.įirst-year students who attended most lectures will have better exam scores than those who attended few lectures.

The number of lectures attended by first-year students has a positive effect on their exam scores. In academic research, hypotheses are more commonly phrased in terms of correlations or effects, where you directly state the predicted relationship between variables. If a first-year student starts attending more lectures, then their exam scores will improve. The first part of the sentence states the independent variable and the second part states the dependent variable. To identify the variables, you can write a simple prediction in if…then form.

Now you should have some idea of what you expect to find. Look for theories and previous studies to help you form educated assumptions about what your research will find.Īt this stage, you might construct a conceptual framework to identify which variables you will study and what you think the relationships are between them. Your initial answer to the question should be based on what is already known about the topic. The question should be focused, specific, and researchable within the constraints of your project.ĭo students who attend more lectures get better exam results? 2. Writing a hypothesis begins with a research question that you want to answer. The dependent variable is the frequency of doctor’s visits - the assumed effect. In this example, the independent variable is apple consumption - the assumed cause. A dependent variable is something the researcher observes and measures.ĭaily apple consumption leads to fewer doctor’s visits. An independent variable is something the researcher changes or controls. Hypotheses propose a relationship between two or more variables. It also has to be testable, which means you can support or refute it through scientific research methods (such as experiments, observations and statistical analysis of data). For some research projects, you might have to write several hypotheses that address different aspects of your research question.Ī hypothesis is not just a guess - it should be based on existing theories and knowledge. It is a tentative answer to your research question that has not yet been tested.

You could conduct a study to compare the test scores of students who stayed up all night with the scores of students who got a full night's sleep prior to the exam. For example, many people believe that staying up all night to cram for a big exam can actually hurt test performance. Folk knowledge is a good source of questions that can serve as the basis for psychological research. Stumped for an idea? Consider some of the following: After all, there are so many different topics you might choose to investigate.
