Models for Pretest-Posttest Data: Repeated Measures ANOVA Revisited.

Jennings, Earl

Journal of Educational Statistics, v13 n3 p273-80 Fall 1988

Eight models that can be used to analyze data from a pretest-posttest design are discussed. Artificial data are used to demonstrate that comparisons among some of the models generate results identical to those obtained by using repeated analysis of variance measures. Such results are shown to be potentially misleading. (Author/TJH)
