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...
