Question

Quizplus · Accepted Answer

Room temperature is not intentionally manipulated by the researcher and is not expected to have any effect on the aggressive responses of the participants. Therefore, it is an extraneous variable that should be controlled for but not treated as an independent or dependent variable. It is also not necessarily correlated with the other variables being studied.
