Answer: They help ensure that changes in the independent variable are affecting the dependent variable.

A controlled variable can be defined as a variable in a scientific experiment. It is a variable that is kept constant and remains unchanged throughout the course of the investigation. It is kept constant to determine the relative relationship between the dependent and independent variables. The changes in the independent variable can be observed or measured in order to determine the effect on the dependent variable.
