In an experiment designed to determine the effects of televised violence on children's aggressive behavior

Question

Quizplus · Accepted Answer

The question presents a confusion between the dependent and independent variables. The amount of televised violence allowed to view is not the dependent variable as it is the variable being manipulated; it is the independent variable. Similarly, children's aggressive behaviors are not the independent variable since they are not being manipulated; they are the dependent variable. Random assignment would be useful to control for individual differences in children's pre-existing levels of aggression and exposure to TV violence, but that was not one of the options presented. Therefore, the correct answer is D, none of these.
