Question

Quizplus · Accepted Answer

The type of film shown (violent vs. nonviolent) is the independent variable because it is being manipulated by the researcher to see if it has an effect on aggressiveness. The control group refers to the group that does not receive the intervention, which in this case would be the nonviolent film group. A placebo effect refers to a perceived effect based on expectations rather than the actual intervention, which does not apply in this experiment. A confounding variable is a variable that could potentially affect the outcome of the experiment, but is not controlled for by the researcher, which the violent film is not.
