Estimating the Generalizability of Multivariate Results.
Schmitt, Dorren Rafael
Generalizability or invariance procedures have been known for over three decades. Through the years, these procedures have not been widely discussed or employed. One reason for the lack of use is that most of the articles on invariance procedures have been mathematically oriented. The mathematical orientation of research articles and the lack of mathematical background on the part of educational researchers have inhibited the use of generalizability procedures. Generalizability procedures are important in educational research due to the frequency of researchers' use of small sample sizes. Problems associated with small samples are compounded by the frequent use of statistical techniques that capitalize on chance and the greater popularity of multivariate techniques. This paper briefly discusses the history of three invariance procedures: (1) cross-validation; (2) jackknifing; and (3) bootstrapping. A discussion of how to use each procedure and an example of each procedure are presented. Three multivariate techniques--canonical correlation, discriminant analysis, and factor analysis--are used for the examples. These same procedures could also be employed with univariate statistics. A 33-item list of references and 13 data tables are included. The computer program used is appended. (Author/TJH)
