Focusing on situations in which analysis of variance (ANOVA) involving the repeated measurement of separate groups of individuals is needed, Girden reveals the advantages, disadvantages, and counterbalancing issues of repeated measures situations. Using additive and nonadditive models to guide the analysis in each chapter, the book covers such topics as the rationale for partitioning the sum of squares, detailed analyses to facilitate the interpretation of computer printouts, the rationale for the F ratios in terms of expected means squares, validity assumptions for sphericity or circularity and approximate tests to perform when sphericity is not met.
Studies with Repeated Measures on One Factor
The accessibility of computers has made complex designs involving more than two factors increasingly popular. The logical extension[Page 60] of the split-plot or mixed design is a three-factor study with repeated measures on one factor. The group factors can be experimental or individual variables.
