A 10-year study of salary differential by sex was undertaken at the University of North Dakota using a multiple regression methodology, with rank, discipline, degree, years in department, years in current rank, and sex as predictors. The sex variable evidenced lower salaries for women when controlling for the other variables throughout the study…

Sex segregation is a powerful phenomenon in childhood. It occurs universally whenever children have a choice of playmates and is found in sub-human primates too. Adults are not directly responsible for sex segregation. Data do not support the hypothesis that the most ladylike girls and the most rough and active boys first form the segregated play…

Meta-analysis is a technique for combining the summary statistics from previously conducted research studies to indicate the direction of results and provide an index of the magnitude of effect size. This paper focuses on the effect of the violation of the assumption of independence (that the value of any included statistic is in no way…

Factors that affect the implementation of professional allied health education programs were studied at 64 four-year black colleges and universities that had no such programs before 1975-76. By 1980, six of the institutions had implemented these programs. Twenty-seven operating ratios and seven institutional characteristics were analyzed, based on…

The final report of the Bilingual Prediction Project presents a review of the project from its inception in 1975 through completion in 1979. The main goal was to predict a student's academic ability in English. A prediction index was constructed in two stages. The first stage was a description of the target population and their school setting, as…

The study described in this paper utilized data from the National Assessment of Educational Progress (NAEP) to compare achievement trends among black and white students with respect to the variable of age at admission to first grade. The three age groups selected were nine, thirteen, and seventeen year olds. NAEP data in reading, mathematics, and…

Job satisfaction has been identified as one of the most important antecedents of turnover, although it rarely accounts for more than 16% of the variance in employee withdrawal. Several data sets collected on the Mobley, Horner, and Hollingsworth (1978) model of turnover were reanalyzed with path analytic techniques. Data analyses revealed support…

A number of laboratory studies have addressed the question of how people integrate different pieces of information to form an overall evaluative judgment. Models of information integration, i.e., the adding model and the averaging model, were tested by gathering questionnaire data from 233 respondents in 17 groups who were expected to vary in…

The extent to which Veterinary Aptitude Test (VAT) scores are valid predictors of veterinary student performance and the effect of a summer enrichment program were assessed for Tuskegee Institute and Auburn University students. In addition, attention was directed to predictors of specialty choices and patterns of specialty choices and employment…

The development of new statistical methods of log-linear models by Leo Goodman has led to major advances in the statistical analysis of categorical data. Goodman's logit analysis, (the simplest form of log-linear models) can be applied in evaluation studies to estimate the "main effects" and "interaction effects" of categorical…

This study examines the relationship between maternal childrearing practices (specifically, nurturance and restrictiveness) and a number of demographic and personality variables. A total of 232 mothers of preschool age children from different socioeconomic levels and ethnic groups participated in the study. Each subject was sent six instruments…

Voting patterns in the 97th United States Congress (1981), in which the Senate was under Republican control for the first time in 30 years, are analyzed. The study measured conservatism from congressional voting analyses made by the Americans for Democratic Action (ADA), Americans for Constitutional Action (ACA), and the Conservative Coalition…

In response to a request from the Charlotte-Mecklenburg Council on Aging, structured interviews were conducted with a random sample of 388 older persons in Charlotte, North Carolina, to assess their needs in the areas of health, transportation, housing, nutrition, information referral, and social participation. A substantial proportion of those…

Drawing from work on the meta-analysis of over 500 validation studies of the General Aptitude Test Battery (GATB) by the U.S. Employment Service, the paper presents a methodological message and a substantive message. Gene Glass's methods, as used by Edwin Ghiselli in personnel selection, ignore study artifacts (sampling error, error of…

The first phase of a study to predict retention and withdrawal among disadvantaged students at an urban commuter institution is described. Variable selection for the study was guided by Tinto's (1975) and Bean's (1982) models. Pilot testing was undertaken to estimate some psychometric characteristics of Pascarella and Terenzini's institutional…
