This study tests the widely cited proposition that 20% of a library's books account for 80% of its circulation. Using data collected for a collection development survey, it was found that of the sample of 4,213 books, 799, or 19%, accounted for 79% of the circulation during 1987. In fact, 25% of the books accounted for all of the circulation that…

This study attempted to determine if there was a change in job attitude among employees of a state institution for the developmentally disabled after a move to new, superior facilities. An attitude scale was constructed and administered in December 1982, prior to the move. A second testing occurred two months later, after Experimental Group I had…

This examination of the reactions of women who are binge eaters to television advertising tested three hypotheses: (1) women who binge experience more negative emotional reactions to television ads, especially ads emphasizing food or weight control; (2) highly feminine women, or women with large real-ideal sex role gaps, react negatively; and (3)…

This paper describes a research and development project in teaching designed to examine whether and how it might be possible to bring the meaning of knowing mathematics in school closer to what it means to know mathematics within the descipline by deliberately altering the roles and responsibilities of teacher and students in classroom discourse.…

This research investigates how individual differences in strategic abilities affect problem solving and, more particularly, the extent to which hypothesis-generating skills predict effective hypothesis testing. Additional questions concerned the effects of content and timing of instructional advice on children's problem-solving strategies, and…

The study investigated statistically significant correlations between levels of test anxiety and socioeconomic status among college sophomores and juniors. The Anxiety Scale (Alpert and Haber) was administered to students in an educational psychology course. Administrations were conducted at a neutral time, 45 days prior to the final exam, and…

Analysis of current methods for achieving compatibility or convertibility between two or more indexing languages draws attention to the need for a switching language to establish equivalency between concepts, not terms. In order to examine the assumption of the conceptual equivalency of identical terms in the indexing languages of related subject…

This paper examined the rank transformation approach to analysis of variance as a solution to the Behrens-Fisher problem. Using simulation methodology four parameters were manipulated for the two group design: (1) ratio of population variances; (2) distribution form; (3) sample size and (4) population mean difference. The results indicated that…

The testing of research hypotheses is directly comparable to the dichotomous decision-making of medical diagnosis or jury trials--not ill/ill, or innocent/guilty decisions. There are costs in both kinds of error, type I errors of falsely rejecting a null hypothesis or type II errors of falsely rejecting an alternative hypothesis. It is important…

A probabilistic hypothesis testing procedure to assess the fit of hypothesized hierarchical structures for test item data is discussed. Statistical procedures are presented which are useful for evaluating the fit of data of a certain class of probabilistic models. These models apply to sets of dichotomous (O,1) responses for which there are…

To test the effect of library instruction on learning basic knowledge and skills in using reference tools, 33 Ball State University students received such instruction in a course on information resources in libraries. In control groups from basic literature courses, 39 students received course-related library instruction and 81 students received…

Results support Sherman's hypothesis that sex differences in tests of field independence, such as Witkin's Rod-and-Frame Test and Embedded Figures Tests, are artifacts of the well-known sex differences in space perception and are therefore not evidence that females are less analytical than males. (Author/BJG)

Simplicity and flexibility of the full rank linear model motivated this paper which introduces researchers to the theory necessary to understand the model and apply the theory in the analysis of some standard fixed effects experimental designs. The theory and examples should help researchers use the model as an experimental tool and a model for…

This paper makes six assertions concerning the artist as experimenter and the means by which artists progress from experiment to experiment. (1) The family resemblances typically cited between the arts and the sciences are trivial, tend to be wish-fulfilling analyses of the common logic of art and science, and promise more than they can deliver.…

An increase in reciprocity of interpersonal attraction during the early acquaintance period followed by continuing social reciprocity are propositions that are central principles of several social psychological viewpoints. However, there is little empirical evidence of increasing reciprocity of interpersonal attraction over time. Two potential…
