Match the following types of variable with their correct definition:

• What is changed in the experiment

• Independent variable

• Other factors that need to be controlled

• Dependent variable

• What is measured in the experiment

• Extraneous variable

A hypothesis is a prediction that a psychologist makes before the experiment as to what they think might happen. A ​ (a)   hypothesis is one where the psychologist believes that changing the independent variable will NOT have an effect on the dependent variable.
