Explanatory variable = Effect of music

Response variable = Memory response

Step-by-step explanation:

An explanatory variable, also known as independent variable, is a variable that can be manipulated so as to analyse their effect on another variable. It is used to predict or explain differences in another variable.

Response variable is a variable whose variation depends on other variable. It is also called a dependent variable.

In this analogy, since the effect of music on memory is what is to be known, music is the explanatory variable while memory is a response variable.
