In any experiment, it is important to choose the sample at random because this gives the experimenter a chance to study different personalities in the sample. If the experimenter decides to choose the children based on their previous behaviors in school or in class, it would be impossible to come up with a conclusive report because some students may naturally have aggressive behaviors even when they do not view violent TV shows.

This is the reason why the experimenter has to choose the children at random in order to have a diverse sample that represents all the behaviors that are exhibited by children.
