Two-factor designs with between-and within-subjects factors
This chapter discusses the examples of between-within (BW) and within-within (WW) designs. The layout of the means table and its interpretation for the WW design follow the same principles as for the BB and BW designs. In the BB design this is called within groups or subjects within groups. In the design WW it is called subjects. In the design BW it is called either subjects or subjects within groups. The concept and technique apply equally in designs which include one or more within-subjects factors except for a detail of the test of significance. Each stimulus was presented in both a control and an experimental version to each subject. There are terms representing the interaction of subjects with any within-subject terms in the design. These all correspond to some form of reliability variation.
