Since canonical correlation analysis subsumes multiple regression as a special case, and since commonality analysis (a variance partitioning procedure) has proven useful in interpreting multiple regression results, the interpretation of canonical correlation results might also be enhanced by the use of commonality analysis. In this paper, a…

Love is among the most fundamental aspects of the experience of being human. Achieving successful love relationships has been associated by counselors--both counseling theories and researchers--with good mental and good physical health. Yet our knowledge of the nature of love remains primitive, because until recently it was not considered…

Most of the multivariate statistical techniques rely on the assumption of multivariate normality. The effects of non-normality on multivariate tests are assumed to be negligible when variance-covariance matrices and sample sizes are equal. Therefore, in practice, investigators do not usually attempt to remove non-normality. In this simulation…

The relationships among the use of self-regulated learning strategies and two important cognitive motivational factors, expectancy of success and task value, were studied using hierarchical regression analysis. Since there are differences in self-regulated strategy use according to level of test anxiety, test anxiety was used as a control…

The need for using invariance procedures to establish the external validity or generalizability of statistical results has been well documented. Invariance analysis is a tool that can be used to establish confidence in the replicability of research findings. Several approaches to invariance analysis are available that are broadly applicable across…

This Monte Carlo study examines whether, given various numbers of variables, treatments, and sample sizes, in a one-way multivariate analysis of variance, Type I error rates of the test approximations provided by the BMDP program, the Statistical Analysis System (SAS), and the Statistical Package for the Social Sciences (SPSS) for Roy's largest…

This study investigates the accuracy of the Woodruff-Causey technique for estimating sampling errors for complex statistics. The technique may be applied when data are collected by using multistage clustered samples. The technique was chosen for study because of its relevance to the correct use of multivariate analyses in educational survey…

The effects on reading speed and comprehension of window proportions and page turning in electronic text were investigated in this study. Subjects--61 undergraduate students at the University of Wisconsin--Whitewater--were administered a standardized reading text displayed as photocopied dot matrix print in simulation of electronic text. There…

Advantages of the use of multivariate commonality analysis are discussed and a small data set is used to illustrate the analysis and as a model to enable readers to conduct such an analysis. A noteworthy advantage of commonality analysis is that commonality honors the relationships among variables by determining the degree to which predictors in a…

This study was undertaken to provide a comparison of primary/elementary teachers' perceptions in Australia and the United States of the skills, competencies, and behavioral attributes that principals should possess to administer an effective school. Utilizing the Audit of Principal Effectiveness, 140 primary teachers in Australia and 347…

The mixed model analysis of variance assumes a mathematical property known as sphericity. Several preliminary tests have been proposed to detect departures from the sphericity assumption. The logic of the preliminary testing procedure is to conduct the mixed model analysis of variance if the preliminary test suggests that the sphericity assumption…

A growing controversy surrounds the strict interpretation of statistical significance tests in social research. Statistical significance tests fail in particular to provide estimates for the stability of research results. Methods that do provide such estimates are known as invariance or cross-validation procedures. Invariance analysis is largely…

Interest in the health care needs and medical care use patterns of older persons has steadily increased in recent years. The major goals of this study were to describe the variability of health services use by older persons and examine the extent to which specific factors moderate the relationship between life stress exposure and subsequent use of…

Traditionally the unit of analysis in marital research has been the individual spouse. More recently the marital relationship has often been defined as a process of interaction and dynamic exchanges such that spouses have autonomous needs as well as corporate needs for interdependence. Thus modern systems theory heightens the importance of both…

The Wechsler Intelligence Scale for Children - Revised (WISC-R) and the Wechsler Intelligence Scale for Children (WISC) were administered in counter-balanced order to 81 children aged 7-12 in New South Wales, Australia. Canonical correlation analysis showed the total redundancy values of WISC-R given WISC and WISC given WISC-R to be .58 and .61…
