This paper presents two extensions of the full-rank multivariate linear model that are particularly useful in multivariate analysis of covariance (MANCOVA) and repeated measurements designs. After a review of the basic full-rank model, an extension is described which allows restrictions of a more general nature. This model is useful in the…

Adolescents' actual and perceived weights were examined in relation to why adolescents think they weigh what they do, where adolescents obtain weight control information, and adolescents' weight locus of control. Significant chi-square differences were found between weight locus of control orientations and actual and perceived weight categories.…

In this paper, scores from the Department of Education's table, "State Education Statistics," are examined to see if they can be used for state-by-state comparisons to aid in the evaluation of educational policies that vary across states. (Author/LMO)

Current practice in structural modeling of variables is limited to means and covariances based on multivariate normality assumptions. This article extends structural equation models to higher order product moments and to non-normal distributions. Areas of possible research are described. (Author/JKS)

Tau, Lambda, and Kappa are measures developed for the analysis of discrete multivariate data of the type represented by stimulus response confusion matrices. The accuracy with which they may be estimated from small sample confusion matrices is investigated by Monte Carlo methods. (Author/LMO)

While the author and Raymond Cattell approach personality study differently, their similar conclusions reveal their constructs and theories as complimentary, not contradictory. They agree on major issues: the existence of general personality traits with consistent associated behaviors, the relevance of multivariate studies, and the importance of…

Investigated the distribution of self-injury in London, Ontario. Multivariate analysis revealed that living arrangements, such as high housing density and single-person households, and low socioeconomic status were closely related to inflated self-injury rates. Self-injury occurred more frequently in the inner city. (JAC)

Advances in cognitive research increase the need for assessment that can address the processes and the strategies by which persons solve problems. Several psychometric models have been introduced to handle claims cast in information-processing terms, explicitly modeling performance in terms of theory-based predictions of performance. Cognitively…

This book looks at quantitative research methods in education. The book is structured to start with chapters on conceptual issues and designing quantitative research studies before going on to data analysis. While each chapter can be studied separately, a better understanding will be reached by reading the book sequentially. This book is intended…

The purpose of this study was to understand the nature of the relationship between organizational strategy and district performance among California's largest unified school districts. Organizational strategy was measured using planned and realized strategies (independent variables). Realized strategy is also referred to strategic orientation.…

This study examined the data selection process preceding multivariate analysis for a data set measuring student motivation and self-regulated learning. Data were 138 responses to a questionnaire on motivation and self-regulated learning, adapted for Finnish students. The first goal was to compare the results gained with "gentle" and…

Less than a year after his inauguration, U.S. President George W. Bush secured passage of the No Child Left Behind Act, the cornerstone legislation of his administration. It was signed into law on January 8, 2002 and cost taxpayers $26.5 billion, the largest dollar increase ever in federal aid. No Child Left Behind is a revised version of the…

Statistical methods are discussed for studying relations between two sets of variables, when each set contains more than one variable. (Author)

A sample of 132 junior high school students completed a biographical data sheet, short forms of the Beck Depression Inventory, a Sensation-Seeking Scale, the Family Environment Scale, a social support index, and a life stress inventory, to determine to what extent depression in young adolescents could be predicted. (Author/PN)

Investigated the effects of fee payment sources on the duration of psychotherapy for 160 outpatients. Univariate results indicated that scaled fee patients had significantly more sessions than those whose fee was paid by Medicaid. Multivariate results, however, indicated that education and sex accounted for most of the variance in treatment…
