Hypothesis - GCSE Psychology Definition

Reviewed by: Raj Bonsor

Published

A hypothesis is a clear and specific statement that predicts what you think will happen in an experiment or study.

In psychology, it often suggests a relationship between two variables. For example, a hypothesis might state that "students who sleep more than eight hours a night will perform better on tests than those who sleep less." It’s important because it gives direction to research and helps scientists know what they are trying to find out.

Once the experiment is done, scientists can see if the results support the hypothesis or not.
