Running head: REPEATED MEASURES Analyzing Repeated Measures Designs Using Univariate and Multivariate Methods: A Primer
نویسنده
چکیده
The present paper presents similarities and differences between the univariate and the multivariate analysis of repeated measures designs. Both methods are illustrated by means of an example. When the data are analyzed using the univariate approach and the homogeneity assumption is violated, three correcting factors are presented. When the data are analyzed using the multivariate approach, the homogeneity assumption is not necessary. The paper also presents the effects on the Type I and/or Type II error rates of violating or not violating the assumption of homogeneity of variance.

Evaluating Performance Improvement through Repeated Measures: A Primer for Educators Considering Univariate and Multivariate Designs
Repeated measures analysis is an important tool for educators committed to evaluating the performance of their students and courses. While evaluations can be performed using a series of t-tests, repeated measures provides practitioners and researchers a more sophisticated tool to analyze the impact of education over time or interventions that employ concurrent tests to measure a particular set ...
متن کاملMANOVA method for analyzing repeated measures designs: an extensive primer.
This article teaches the multivariate analysis of variance (MANOVA) method for repeated measures analysis to researchers who are already familiar with regular analysis of variance (ANOVA) methods. Repeated measures designs are traditionally analyzed with mixed-model ANOVAS. However, sphericity violations markedly affect the true Type I error rates and power for the mixed-model tests. However, t...
متن کاملA Comparison of Data Analysis Strategies for Testing Omnibus Effects in Higher-Order Repeated Measures Designs.
Methods for analyzing repeated measures data, in addition to the conventional and corrected degrees of freedom univariate and multivariate solutions, are presented in this review. These "newer" methods offer researchers either improved control over Type I errors and/or greater power to detect treatment effects when (a) certain assumptions are violated, and/or (b) missing data exists. In particu...
متن کاملComparison of aligned Friedman rank and parametric methods for testing interactions in split-plot designs
Parametric methods are commonly used despite evidence that model assumptions are often violated. Various statistical procedures have been suggested for analyzing data from multiple-group repeated measures (i.e., split-plot) designs when parametric model assumptions are violated (e.g., Akritas and Arnold (J. Amer. Statist. Assoc. 89 (1994) 336); Brunner and Langer (Biometrical J. 42 (2000) 663))...
متن کاملRepeated Measures in Randomized Block and Split Plot Experiments
Randomized block and split plot designs are among the most commonly used experimental designs in forest research. Measurements for plots in a block (or subplots in a whole plot) are correlated with each other, and these correlations must be taken into account when analyzing repeated measures data from blocked designs. The analysis is similar to repeated measures analysis for a completely random...
