The predictive validity of the Scholastic Aptitude Test (SAT) for Mexican-Americans is investigated. Forty-two Mexican-American freshmen students who entered the University of California, Riverside, in the Fall 1971 participated in the study. Analyses of variance concerning ethnic groups on GPA (grade point average) and SAT verbal (SATV) and math…

Four styles of professional-organizational functioning were identified through a factor analysis of questionnaire data. The questionnaire was based on a conceptual framework derived from the literature administered to a cross section of educational practitioners. The four styles were found to be differently related to four constructs and several…

This methodological study investigated which fertility values are correlated with the variable of desired family size. Data was gathered from 310 Caucasian Protestant, Catholic, and Jewish women from the Buffalo metropolitan area. The subjects were between the ages of 15 and 44, lived with their husbands, and had either none, one, two, or four…

The purpose of this dissertation is to estimate the relation between hours worked and sources and levels of income as well as other market and personal factors for selected groups of low-income family heads grouped into four categories conforming to expected welfare eligibility requirements. Multivariate least-squares regression techniques…

In a multiple (or multivariate) regression model where the predictors are subject to errors of measurement with a known variance-covariance structure, two-sample hypotheses are formulated for (i) equality of regressions on true scores and (ii) equality of residual variance (or covariance matrices) after regression on true scores. The hypotheses…

Perinatal variables were used to predict 7-year outcome for 538 children, 32% Negro and 68% white. Mother's age, birthplace, education, occupation, marital status, neuropsychiatric status, family income, number supported, birth weight, one- and five-minute Apgar scores were regressed on 7-year Verbal, Performance and Full Scale IQ, Bender, Wide…

A set of symbols is presented along with logical operators which represent the possible manipulations of the linear model. The use of these symbols and operators is to simplify the representation of analysis of variance models, correlation models and factor analysis models. (Author)

While many studies have predicted elementary school achievement, few have investigated both cognitive and biographical predictors simultaneously in a multiple regression format. The present study used both types of variables in predicting achievement over a 20 month span. Criterion variables consisted of Stanford Achievement Test subscores, and a…

The study investigated the possible influence of selected personal and background demographic variables on job satisfaction among industrial arts teachers and the relationships between job satisfaction and a job content-context dichotomy for the job factors. Data were collected through mailed questionnaires to a 50 percent sample of industrial…

This final report summarizes past research and suggests new approaches to the problem of estimating long-term individual constants using path analysis. The general objective of the research was to detect and measure the likelihood that one variable, x, measured at time, t, has a causal influence on another variable, y, measured at a subsequent…

The purpose of this dissertation is to provide evidence bearing on the question of the influence of the grades students receive on their ratings of the college teachers who gave them those grades. Specifically, certain characteristics of the grade distribution within each course section are evaluated as predictors of the students' ratings of the…

This study was undertaken to compare the variables related to the successful institutionalization of changes across divergent organizations, and to design, through cross-validation, an interorganization model of change. Descriptive survey questionnaires and structured interviews were the instruments used. The respondent sample consisted of 1,500…

The three-year impact of a remedial arithmetic program on eligible St. Louis Public School pupils was investigated. Hypotheses were tested through multiple linear regression models for analyses of covariance. No treatment effects were found. The study reveals that changes in future program evaluation designs are needed. (Author/JKS)

The results of a recent investigation of the relationship of Law School Admission Test score and undergraduate grade point average with first-year average in law school for 4,655 minority students who began law school in 1983 and 1984 are described. (MLW)

Reports on a study of the influence of cognitive/affective variables on the second language learning ability of adults. Two variables, field independence and ambiguity tolerance, were found to be significant predictors of English as a second language proficiency for international students studying in the United States.
