Describes an experiment that aimed to help bereaved teenagers through peer group counseling, and examines the related issue of how reliably the effectiveness of this counseling can be measured. This involved a systematic approach to the subjective impressions of participants, as well as objective measurement techniques. (JPS)

Some specific opportunities and techniques are described for combining and integrating qualitative and quantitative methods from the design stage of a substance abuse program evaluation through implementation and reporting. The multiple problems and requirements of such an evaluation make integrated methods essential. (SLD)

Type I error rate and power for the t test, Wilcoxon-Mann-Whitney test, van der Waerden Normal Scores, and Welch-Aspin-Satterthwaite (W) test are compared for two simulated independent random samples from nonnormal distributions. Conditions under which the t test and W test are best to use are discussed. (SLD)

Provides a philosophical framework for the development of information literacy programs integrated into school curriculums; reports on research in Australia that examines the impact of integrated information literacy programs on secondary school student learning and attitudes; and explores general principles for information literacy instructional…

Several extensions to the Angoff method of standard setting are described that can accommodate characteristics of performance-based assessment. A study involving 12 panelists supported the effectiveness of the new approach but suggested that panelists preferred an approach that was at least partially conjunctive. (SLD)

Reports on a study that explored the hypothesis that ethnic differences in mortality trends would shed light on the rectangularization debate. Using California population data from 1970, 1980, and 1990, ethnic differences in rectangularization were examined using both visual and means and standard deviation analyses. Resulting patterns varied by…

Multiple program impact analysis was used to evaluate the overall effectiveness in programs for 11,766 first-year students at the University of Texas at Austin. The technique examines the relationship between involvement in multiple educational programs and selected educational outcomes. Among findings was that participation in more than one…

Proposes a model for technical journal deselection based on the Bradford law of distribution. The model's operational prescriptives, characteristics of the Bradford distribution in the field of pediatrics, and relevance to collection management are discussed. (42 references) (KRN)

Examines historical roots of the link between statistics and psychology, exploring the way in which the conceptual framework for the application of probability in psychological research was created by experimental design. In the social sciences, statistics creates and defines objects of study more directly than in the physical sciences. (SLD)

Describes a project that was designed to study the effectiveness and efficiency of editing procedures within an online bibliographic system at a large research university library. A comprehensive statistical overview of editing commands available is presented, frequency of their use is studied, and questions for further research are suggested.…

Reports on a statistical analysis of English-as-a-Second-Language (ESL) student evaluations of teachers in two large programs. Results indicated a systematic bias occurs in ESL student evaluations, raising issues of fairness in the use of student evaluations of ESL teachers for purposes of personnel decisions. (21 references) (GLR)

Provides a conceptual framework for information systems (IS) that can be used in AIDS intervention and prevention (AIP). System components are analyzed, including a database, decision support systems (DSS), expert systems, and software; potential applications of ISAIP are suggested; and an example of a system implemented at Wright State University…

Reviews three citation-based measures for the study of journal status--influence weight, importance index, and measure of standing--to provide more convenient access to their computation. A subset of nine library and information science journals is used to illustrate simple computational procedures using the SAS statistical software package. (18…

Various methods for calculating and presenting results of information retrieval (IR) evaluation research are discussed, with illustrations from recent laboratory results. Highlights include measures for calculating recall and precision, user needs for high or low level of recall, and comparisons of Boolean and ranked output retrieval. (22…

A procedure for smoothing proportions of a double-entry expectancy table is described. The product is a nomograph from which can be read expectancies from combinations of values of two predictor variables. Use of the procedure in admission of first-year college students, based on students' high school class rank and standardized test composite…
