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 in Chapter 10.)

Dr. Jones conducts a study examining the relationship between viewing violent television and aggressive behavior of 5-year-old boys. Television preferences are obtained by interviewing each child. Based on the interview results, the boys are divided into two groups: those who prefer violent television and those who prefer nonviolent television. Then aggressive behavior is measured by observing the children during an outdoor play period to determine if there is any difference between the two groups.
