The grades on the psychology examinations from the research above are the <u>dependent </u>variables.
<h3>What is a Dependent Variable?</h3>
This refers to the variable that relies on the other factors that are being measured examined, or evaluated. The test score above is a dependent variable because it can change depending on other factors such as:
- the quality of the study guide,
- the quality of the textbook,
- how much of the study guide was used by the psychology students etc.
The test scores are bound to change as the above factors change, hence, it is dependent.
