After reading this chapter, you should be able to:
- Delineate the between-subjects design and the between-subjects experimental design.
- Distinguish between an experimental group and a control group.
- Explain how random assignment, control by matching, and control by holding constant can make individual differences about the same between groups.
- Identify the appropriate sampling method and test statistic for independent samples to compare differences between two group means, and among two or more groups.
- Delineate the within-subjects design and the within-subjects experimental design.
- Demonstrate the use of counterbalancing and control for timing using a within-subjects experimental design.
- Identify the appropriate sampling method and test statistic for related samples to compare differences between two or more group means.
- Contrast the use of a between-subjects versus a within-subjects design for an experiment.
- Identify the appropriate sampling method for a factorial design used in an experiment.
- Identify and describe three types of factorial designs.
- Identify the implications of using a quasiindependent factor in a factorial design.
- Describe the higher-order factorial design.
