Control variables are needed to “control” for factors that would otherwise influence the measurement of marketing.These are the factors that impact your business based on the external environment.

These variables could include competitive activity, category trends, macroeconomic factors, seasonality and distribution, among others.

Control variable should not be confused with controlled variable, which is an alternative term for independent variable.
