Question

Karen is investigating if age has any effect on political party preferences. What is the explanatory variable?

Answer 1

Using variable concepts, it is found that the explanatory variable is the age.

Explanatory and response variables:

• The variables of an experiment are divided into explanatory and response.

• The response variable is the one that is the focus of the study, that is, the one that can be changed.

• The explanatory is the one that explains the reason of the change in the response variable.

In this problem, the age can effect the political party preference, hence:

• The variable that is changed is the political party preference, hence it is the response variable.

• The reason is the age, hence it is the explanatory variable.
