    One of the major learning objectives of this chapter is to define a factorial research design, including the terms factor and level, and to identify and describe factorial designs when they appear in a research report. The goal of experiments is to establish the existence of a cause-and-effect relationship between two variables. To accomplish this goal, the researcher manipulates one variable (that is, the independent variable) and measures a second variable. Nonexperiments and quasi-experiments are similar to experiments except that...

    contrasting a repeated measures research design with matched subjects and independent measures designs A graduate student is interested in whether journaling can affect grief and healing. She has participants who have been widowed within the past 10-14 months complete a battery of psychological questionnaires before and after journaling about their daily problems for 2 months. The first time the graduate student conducted this study, she used a repeated-measures design and compared the widows' and widowers' baseline scores with their scores...
