Quizplus · Accepted Answer

The dependent variable is the variable that is measured or observed by the researcher, and in this case, it is the driving behavior. The independent variable is the variable that is manipulated by the researcher, which is the blood alcohol level. The control variable is a variable that is held constant or unmanipulated in order to minimize the effects of extraneous variables. The manipulated variable is another term used for the independent variable, as it is the variable that is intentionally changed by the researcher.
