<h3>What is a Dependent Variable ?</h3>
A dependent variable is the variable that changes as a result of the independent variable manipulation.
- For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores since that is what is being measured.
- The easiest way to identify which variable in your experiment is the Independent Variable (IV) and which one is the Dependent Variable (DV) is by putting both the variables in the sentence below in a way that makes sense. “The IV causes a change in the DV. It is not possible that DV could cause any change in IV.”
