ABSTRACT
L2 researchers can combine a repeated-measures ANOVA (Chapter 11) with a between-groups ANOVA (Chapter 9). Such a combination allows researchers to simultaneously examine the effect of a between-subject variable, such as length of residence or type of treatment, a within-subject variable, such as test time (e.g., pre, post, and delayed post) or task type (e.g., implicature, routines, and speech acts), and the interaction among these variables. This chapter explains how a two-way mixed-design ANOVA can be performed in SPSS and extends what has been discussed in Chapter 11.
