Quizplus · Accepted Answer

The independent variable is the one that is being manipulated or changed in an experiment, which in this case is whether or not a subject receives a drug. The dependent variable is the behavior being measured, which is not mentioned in this question. Control variables are the ones that are held constant to prevent them from influencing the dependent variable, and random variables are not specifically mentioned in this question.
