Explanation:

In experimental design, the independent variable is the one that the experimenter manipulates or controls to observe its effect on the dependent variable. The dependent variable is what is measured, variability refers to the spread of data, and a confounding variable is an extraneous variable that can affect the relationship between the independent and dependent variables. So the variable controlled by the experimenter is the independent variable.
