ABSTRACT
This chapter extends the mixed-model methodology developed in Chapter 11 for one-way within-subjects designs to more complicated factorial designs. In this respect, this chapter is related to Chapter 11 just as Chapters 7 and 8 are related to Chapter 3 for between-subjects designs. We will see that the concepts developed in Chapters 7 and 8 for between-subjects factorial designs are applicable for within-subjects factorial designs as well. The only real difference is that the statistical tests must once again take into account the fact that the design involves a within-subjects factor.
