The next questions refer to the situation described below. In an experiment designed to determine whether watching violent scenes on television increases the frequency of aggressive behavior in children, one group of subjects saw a nonviolent cartoon and another group saw a violent cartoon.

This is because the experiment was about determining whether watching violent scenes on television increases the frequency of aggressive behavior in children so those that watched the nonviolent cartoon really didn't matter.
