A reduction in agricultural activity in a rural farming community will result in reduced activity in almost every sector of the local economy. The result may be measured in loss of employment and income. This report provides a method to estimate such economic impacts with a minimum of data collection and manipulation. Most of the input data…

The relationship between analysis of variance (ANOVA) methods and their analogs (analysis of covariance and multiple analyses of variance and covariance--collectively referred to as OVA methods) and the more general analytic case is explored. A small heuristic data set is used, with a hypothetical sample of 20 subjects, randomly assigned to five…

Principals exhibiting different kinds of administrative behavior tend to be influenced by different kinds of factors, according to the results of two sets of related studies reported in this document. The first set, consisting of three studies of principals and central administrators, explored the factors shaping principals' behaviors when the…

A 12-month outcome study was conducted on 129 patients discharged from a hospital-based substance abuse treatment program in an effort to identify the progress of patients after treatment, evaluate the treatment program, and improve the program based on the evaluation. Subjects completed two demographic questionnaires and a 12-month post-discharge…

The relationships between medical school academic achievement and first year residency performance were investigated for the 1983 and 1984 graduates of the Medical College of Wisconsin. The analyses were designed to control for suspected differential resident expectations among the directors of various medical specialties, and were replicated to…

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…
