One-Way, Repeated-
Measures ANOVA

LEARNING OBJECTIVES

  • Describe what repeated-measures ANOVA does.

  • Complete a one-way, repeated-measures ANOVA.*

    *Note: Formulas for calculating sums of squares appear in an appendix at the end of the chapter.

  • Interpret a one-way, repeated-measures ANOVA.

CHAPTER OVERVIEW

The last chapter introduced between-subjects, one-way ANOVA, an extension of the independent-samples t test to situations in which more than two independent samples are being compared. Just as the chapter on independent-samples t tests was followed by a chapter on paired-samples t tests, the chapter on between-subjects, one-way ANOVA is followed by a chapter on within-subjects, measures one-way ANOVA. Said another way, the chapter on ANOVA for independent samples is followed by this chapter on ANOVA for dependent samples. Repeated-measures, one-way ANOVA is an extension of paired-samples t tests to situations in which there are more than two dependent samples.
