Quizplus · Accepted Answer

The independent variable is the variable that is manipulated by the experimenter, in this case, the room temperature. The other options are either dependent variables (performance on exams) or extraneous variables (college students, expectations of increased performance) that may affect the outcome but are not being intentionally manipulated by the experimenter.
