Quizplus · Accepted Answer

The independent variable is the one that is being manipulated or varied by the experimenter. The other options are not directly related to this definition. The control variable is the one that is kept constant in order to eliminate its effects on the dependent variable, the operational variable refers to how the variable is defined and measured, and the dependent variable is the one being measured or observed in response to changes in the independent variable.
