A study was conducted to detect possible bias in the prediction of school achievement with family background variables and the effects of biased selection on the classifications of exceptional schools. Bias was examined by testing the equality of subpopulation regressions for predominately Black, Hispanic and White school subgroups. Significant…

This study was conducted using archival data for 300 students of the graduating class of 1980 in a public school system which had a minimum competency testing (MCT) program. Data on normative variables (age, sex, race, and ability test scores) and performance variables (high school course of study, grade point average, absenteeism, and truancy)…

A general linear model (GLM), using least-squares techniques, was used to develop a criterion measure to replace freshman year grade point average (GPA) in college admission predictive validity studies. Problems with the use of GPA include those associated with the combination of grades from different courses and disciplines into a single measure,…

The primary purpose of this study was to examine uneven early development in premature infants. A multiple regression analysis was performed in which birth weight, length of gestation, length of assisted feeding, and length of ventilation were used to predict the descrepancy between a child's Psychomotor and Mental Scale scores on the Bayley…

To examine and clarify background conditions for understanding variables which affect salary, the salary and compensation programs at two industrial and three educational organizations were subjected to a statistical audit. Data were available on 272 employees. Ten compensation variables were studied as having direct or indirect effects on salary:…

Six methods for smoothing double-entry expectancy tables (tables that relate two predictor variables to probability of attaining a selected level of success on a criterion) were compared using data for entering students at 85 colleges and universities. ACT composite scores and self-reported high school grade averages were used to construct…

The aim of this study is to suggest an alternative to the essay testing method of assessing structural understanding of concepts, which suffers from time constraints and lack of scoring reliability. In this method, students' relationship judgments between concept pairs are examined directly rather than by means of multidimensional scaling analysis…

This study identified variables which would predict first semester grade point average of nursing students. A variety of academic, psychological, and sociological data were obtained for 630 students attending three schools of nursing within the state of Indiana over a three-year period. High school grade point average, Nelson-Denny vocabulary…

The usefulness of multiple correlation as an extension of one group evaluation designs was investigated. Program participants were measured on the amount of time each spent participating in a specific activity. This information, along with selected personal variables, was used in a correlational analysis to determine the contribution of various…

The effects of the violation of the assumption of normality coupled with the condition of multicollinearity upon the outcome of testing the hypothesis Beta equals zero in the two-predictor regression equation is investigated. A monte carlo approach was utilized in which three differenct distributions were sampled for two sample sizes over…

This is an empirical study of selected learner characteristics and their relation to academic success, as indicated by course grades, in a structured independent study learning program. This program, called the Audio-Tutorial System, was utilized in an undergraduate college course in the biological sciences. By use of multiple regression analysis,…

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…

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…

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…

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…
