Not to be confused with Control variable (programming) or Control variable (statistics). The control variable (or scientific constant) in scientific experimentation is the experimental element which is constant and unchanged throughout the course of the investigation.
The dependent variable is dependent on the independent variable, and the independent variable is independent of the others. Control variables are controlled to make sure that the independent variable is the only factor causing a change in the dependent variable.f you think of the independent variable as the cause, then the dependent variable is the effect. If the independent variable is not the only factor that could affect the dependent variable, then you would have to make this factor a control variable. This is a variable that is controlled during and between experiments.
