Quizplus · Accepted Answer

An independent variable is the variable that is manipulated or changed by the experimenter in order to observe its effect on the dependent variable. The dependent variable is the variable that is being observed or measured as a result of changes in the independent variable. The control variable is a variable that is kept constant or consistent throughout the experiment to ensure that any changes observed in the dependent variable are a result of changes in the independent variable alone. The experimental variable is not a commonly used term in scientific research.
