Evaluating Performance Improvement through Repeated Measures: A Primer for Educators Considering Univariate and Multivariate Designs
نویسندگان
چکیده
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 of knowledge, skills, or attitudes. This paper provides educators with the information they need to choose between and interpret results based on the univariate and multivariate approach to repeated measures analyses. It also serves to explain the sphericity assumption and its impact on repeated measures designs.

Running head: REPEATED MEASURES Analyzing Repeated Measures Designs Using Univariate and Multivariate Methods: A Primer
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 ...
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...

One of the main techniques used in data mining is data clustering, which has many applications in computer science, biology, and social sciences. Constrained clustering is a type of clustering in which side information provided by the user is incorporated into current clustering algorithms. One of the well researched constrained clustering algorithms is called microaggregation. In a microaggreg...
متن کاملDiscriminant Analysis for Repeated Measures Data: A Review
Discriminant analysis (DA) encompasses procedures for classifying observations into groups (i.e., predictive discriminative analysis) and describing the relative importance of variables for distinguishing amongst groups (i.e., descriptive discriminative analysis). In recent years, a number of developments have occurred in DA procedures for the analysis of data from repeated measures designs. Sp...
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...
