Discriminant analysis is reviewed in terms of: (1) formulations, (2) interpretations, (3) uses, (4) issues and problems in applications, (5) recent developments and conceptualizations, and (6) general references and computer programs. Four aspects of a discriminant analysis are considered. They are: (1) separation: determining intergroup…

Parental reaction to open education in North Dakota was studied. The hypotheses predicted that there would be less parental acceptance of and support for the open classroom according to: the greater the classroom openness; the less the parents' cosmopoliteness, the smaller the town population, the older the parents, the lower the informational…

The effects of violation of the assumption of homogeneity of regression on the Type I error rate and on the power of analysis of covariance (ANCOVA) were investigated. The data situations included in the study involved two groups with one covariate and one criterion, with varying equal and unequal group sizes, and varying degrees of violation of…

The educator today often makes decisions in the face of uncertainty. Although many of these decisions have widespread implications, all too often these determinations are made without benefit of an appropriate decisionmaking procedure. The educator should identify those variables important to arriving at decisions about students' grades, student…

To answer questions concerning the simple and multivariate relationships of intelligence, divergent thinking, and self-concept with reading achievement, measures of verbal divergent thinking and self-concept were administered to 188 students from an urban, lower middle class, elementary school. Reading achievement and intelligence scores were…

In 1965 the Court of Appeals of Kentucky ruled that all property should be assessed at 100 percent of fair market value. In compliance with the court decision, the county assessors began reassessing properties in January 1966. A great controversy arose over the new assessment procedures and problems. This study evaluates the results of the 1966…

This study analyzes the recruitment, selection and compensation of laborers and beginning clerical workers in the Wheeling and Steubenville-Weirton areas during the middle 1960's. The validity of various assumptions regarding the tie between workers characteristics, adjusted wages offered, and recruitment methods was tested and the impact of other…

Progress made to date in efforts to lay the groundwork for establishing meaningful and on-going procedures for the assessment of the performance of educational systems in New York is reported. The need for educational performance indicators is that indicators would provide a series of measures to show how well educational systems are performing,…

Twenty-nine community characteristics were studied to determine which were statistically most useful as predictors of per-pupil Federal aid to the 169 school districts of Connecticut. Three regression models were developed using community traits as predictors of Federal aid allocations. Cross-validation of regression models to predict future…

The objective of the study was to predict potential procrastinators in a self-pacing instructional system. Seventy-five entering college freshmen were randomly selected to participate in a large scale individually-paced program. Those students (25) who procrastinated were classified as "no-start-procrastinators" (NSP); the remainder (52) were…

When interpreting the results of a norm-referenced testing program, the availability of several expectations of test scores is desirable. Toward this objective, academic aptitude test data (the Short Form Test of Academic Aptitude) and school socioeconomic data were collected from the participants in the 1970 standardization of the California…

The relationship between the perceptual organization of junior college instructors and student ratings of their effectiveness as teachers is explored. The major hypothesis of the research was that there would be a significant positive relationship between student ratings of faculty effectiveness and certain aspects of perceptual organization. The…

An econometric model is formulated that explains income per person in various compartments of the labor market defined by three main levels of education and by education required. The model enables an estimation of the effect of increased access to education on that distribution. The model is based on a production for the economy as a whole; a…

Four techniques for assessing differences between least-squares estimators of regression coefficients from group and individual-level data are summarized. The utility and suitability of all four approaches are discussed when (1) data are grouped by a nominal characteristic; (2) there are multiple regressors; or (3) individual-level data cannot be…

Three approaches to the prediction of juvenile recidivism--factor analysis, stepwise multiple regression, and stepwise discriminant analysis--are contrasted. Stepwise discriminant analysis provided the most consistent selection of variables in the data set used. Problems and advantages of the three approaches are discussed. (Author/JKS)
