A study to compare cognitive functioning in acutely and chronically sleep-deprived house officers is described. A multivariate analysis of variance revealed significant deficits in primary mental tasks involving basic rote memory, language, and numeric skills. (Author/MLW)

The study tests the appropriateness of multiplicative versus additive expectancy-valency models for grouping motivational force decisions of 82 undergraduate students. Arguments are offered favoring a non-nested regression models analysis over a traditional hierarchical analysis of nested regression models. Discriminant analysis indicated one of…

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 third component of our three-part series focuses on students who attained a bachelor's degree and what it took to get there. We used multiple regression analysis to determine the factors that seemed to matter on the pathway to the BA. The appendix of this report provides methodological details to this analysis. (Contains 2 footnotes and 7…

An empirical study of statistical overkill investigated the generalizability of multiple regression equations as a function of the subject/variable ratio. Data from various-sized groups of rehabilitation clients were used to develop the equations. Findings showed that equations developed on samples with less than a 10 to 1 ratio failed to…

This paper presents a number of inferential statistical models that may aid the operant investigator in presenting his data. (Author/RK)

The proposed model can be likened to a moving least squares'' model. It uses a data search procedure in which the intent is to evaluate a number of variables substantively, rather than in terms of formal statistical procedures. (Author)

A case study utilizing cross sectional regression analysis to predict whether or not the correct expenditures are being made for school athletics. Regressions are run for athletic cost per pupil vs school population, number of coaching assignments vs school population, and coaching expenditures vs coaching assignments. (DN)

Eight of the hypotheses supported by the Harvard data were again supported in the Montreal sample, though only two of the replications reached statistical significance. (Authors)

Paper reviews the test for regression lines and provides equations for expanding this test to regression planes. (Author)

The general problem of using group status to estimate true scores given multiple measures is considered in this paper. (Authors)

Results of stepwise regression analyses of text characteristics on learning scores revealed that the same characteristics which predict comprehension also predict new learning. (Author/MB)
