For each of the following scenarios, identify which research strategy is used: descriptive, correlational, experimental, or nonexperimental. (Note: For now, do not differentiate between nonexperimental and quasi-experimental studies. The distinction between them is discussed later)
The relationship between viewing violent television and aggressive behav-ior of 5-year-old boys. A group of boys is randomly separated; half the boys are shown violent television programs for 30 minutes before play time and the other half of the boys are shown nonviolent television programs during the same period. Aggressive behavior is then measured by observing the children during an outdoor play period to determine if there is any difference between the two groups.
