Repeated Measures and Mixed Designs ANOVA Using SPSS.
Aiken, Lewis R.
Although the Statistical Package for the Social Sciences (SPSS) contains no subprogram that is complete in itself for analyzing repeated measures or mixed designs analysis of variance, subprogram ANOVA can be used to obtain almost all the required sums of squares for repeated measures designs, mixed designs having repeated measures on some elements, or designs with one or more nested factors. The analysis of either single- or multi-factor designs with repeated (within-subjects) measures on all factors is straightforward, and entails the same number of analyses as the analysis of mixed designs involving both between- and within-subjects factors using SPSS. With more complex designs, such as one in which there are two or more within-subjects factors, the data cards need to be stacked in a special way and two or more SPSS control decks are required. By analyzing the design into its component sums of squares and numbers of degrees of freedom, and then applying subprogram ANOVA successively with appropriate changes in the independent variables and the unit of analysis, the sums of squares for any mixed design may be obtained.
