The application of a multivariate analytic technique for the analysis of data from longitudinal designs with multiple dependent variables is presented. The technigue is the multivariate generalization of univariate repeated measures ANOVA. An application of the technique to data collected using materials from the Asian Studies Curriculum Project…

In recent research the assessment of worry and emotionality as separate components of test anxiety has become a salient point. Because of theoretical advances in this field it seems to be necessary to include both aspects in the measures that are used to assess test anxiety. Some literature on this distinction is available, but no longitudinal…

Hirschi's social control theory of delinquency status that delinquency involvement is the function of the failure of an adolescent to form or maintain a bond to society comprised of attachment, commitment, involvement and belief. In the past decade Hirschi and other researchers have found substantial support for this original thesis using tabular…

A general framework for making mastery/nonmastery decisions based on multivariate test data is described in this study. Over all, mastery is granted (or denied) if the posterior expected loss associated with such action is smaller than the one incurred by the denial (or grant) of mastery. An explicit form for the cutting contour which separates…

A CONTINUATION STUDY OF USOE PROJECT NUMBER 1493 EXTENDED THE EXAMINATION OF PROBLEMS IN USING MULTIVARIATE SCALING TECHNIQUES FOR THE MEASUREMENT OF INTERESTS. AN EXPERIMENTAL INSTRUMENT, SIMILAR IN FORMAT TO THE SOCIAL RELATIONS SCALE CONSTRUCTED BY GARDNER AND THOMPSON (1956), WAS PREVIOUSLY DEVELOPED. SUBTESTS ON THIS INSTRUMENT (THE INTEREST…

Rotation of canonical components is contrasted with factor rotation and the concept of communalities in canonical analysis is considered. Three possible strategies for rotating canonical components are described: single rotation of all components, separate rotation of each set, and sequential rotation of one set then the other. Constraints,…

The method of unweighted means in the multivariate analysis of variance with unequal sample sizes was investigated. By approximating the distribution of the hypothesis sums-of-squares-and-cross-products with a Wishart distribution, multivariate test statistics were derived. Monte Carlo methods and a numerical example illustrate the technique.…

Comments on Kerwin et al.'s article on Covariance Structure analysis (LISREL). Concerns include assumptions about requirements for causal inferences, psychometric properties of measurement scales, validity of the indicators of each latent variable, completeness of the structural model, linearity of the latent variables, and the joint distribution…

Variance stabilizing transformations yield statistics whose standard errors are only influenced by the number of observations on which they are based. A solution that can be extended to inference on all of these parameters is presented and illustrated via three examples. (TJH)

A review of model-selection criteria is presented, suggesting their similarities. Some problems treated by hypothesis tests may be more expeditiously treated by the application of model-selection criteria. Multivariate analysis, cluster analysis, and factor analysis are considered. (Author/GDC)

A multivariate model is proposed for assessing a severe discrepancy between intellectual ability and actual achievement in learning disabled (LD) children. Formulas for computing universe difference score variance, the standard error of the difference score, and its generalizability coefficient are given. (Author)

The basic notion of variability is generalized from a univariate context to a multivariate context using two matrix functions, a determinant, and a trace, yielding a number of alternative multivariate indices of shared variation. Some problems in the interpretation of tests of multivariate hypotheses are reviewed. (Author/BW)

Because ignoring the missing data in an evaluation may lead to results that are questionable, this study investigated the effects of use of four missing data handling techniques on a survey instrument. A questionnaire containing 35 5-point Likert-style questions was completed by 384 respondents. Of these, 166 (43%) questionnaires contained 1 or…

The AIDS epidemic is making orphans out of many African children and threatens to reverse hard-won gains in raising school enrollments. The average gross primary enrollment ration (GPER) the number of children enrolled as a percent of the total number of children of school age was only 77% for Sub-Saharan Africa in 1996. The countries are hard-hit…

This study investigated the attitudes toward statistics of graduate students who studied advanced statistics in a course in which the focus of instruction was the use of a computer program in class. The use of the program made it possible to provide an individualized, self-paced, student-centered, and activity-based course. The three sections…
