In statistics, the response variable is the variable you are measuring and trying to explain. When you have a response variable, it is always paired with one or more explanatory variables. The explanatory variable(s) drives change in the response variable.What are response and predictor variables?
Predictor variables are also known as independent variables, x-variables, and input variables. A predictor variable explains changes in the response. Typically, you want to determine how changes in one or more predictors are associated with changes in the response.
