Generally, this paper aims to: (1) provide clarification, quantification, and some mathematical analysis to the statistical problem of restricted range in a college admissions situation; and (2) discuss various questions related to the problem of selection strategies. (Author/PN)

The purpose of this study was to compare five predictor models, including two least-square procedures, two probability weighting (semi-Bayesian) methods, and a Bayesian model developed by Lindley. (See also TM 501 088, TM 501 089, and TM 501 090) (Author/NE)

Four commonly employed procedures were repeatedly applied to computer-simulated samples to provide comparative data pertaining to two questions: (a) which procedure can be expected to produce and equation that yields the most accurate predictions for the population, and (b) which procedure is most likely to identify the optimal set of independent…

The results of a replication study are described that tested the predictive validity of a 34-item instrument designed to assess the fundamental constructs of Tinto's model of college student attrition. Potential institutional differences in faculty members' influence on retention were identified. (Author/MLW)

The purpose of this study is the cross-validation of the predictive validity of the Minnesota Teacher Attitude Inventory (MTAI). Designed by the writer two decades ago, this instrument purposes to assess attitudes of teachers toward pupils as one important factor in teacher personality. The present study attempts to cross-validate predictive…

Base expectancy tables developed by the California Youth Authority apply to total population of male wards released on parole by the state. Subpopulations of relatively homogeneous make-up offered the possibility of developing base expectancy tables of greater predictive ability. Multiple regression analysis showed the overall advantages and…

An empirical study of statistical overkill investigated the generalizability of multiple regression equations as a function of the subject/variable ratio. Data from various-sized groups of rehabilitation clients were used to develop the equations. Findings showed that equations developed on samples with less than a 10 to 1 ratio failed to…

The generation of empirically-based equations is within the grasp of most researchers in occupational education. This paper was designed to develop a sensitivity to the need for cross-validation in these circumstances. Program CROSVAL is a means of bridging the gap between the need for, and mechanization of, cross validation. (Author/DS)

Compares, within the context of parole decision making, the predictive utility of five statistical methods commonly used to develop correctional risk-screening devices. Results suggest that no apparent empirical advantage accrues to any particular model. Further, most devices developed are highly intercorrelated. (Author)

Empirical studies addressing admission to and graduation from a doctoral program focusing on educational leadership are noticeably absent within the professional literature, and this study seeks to fill partially this void through testing specific hypotheses. Archival data were used to conduct a three group discriminant analyses where the…

Stability and predictive validity in the language and play development of 41 toddlers were studied. Links between language and symbolic play of toddlers were examined at 13 and 20 months in terms of homotypic, heterotypic, or mediated models of association. In the homotypic model, performance on a variable is related to performance on the same…

Discusses a survey investigation of whether exposure to television violence is associated with an increased probability of engaging in violent behavior. Questionnaire data collected in 1970 in junior and senior high schools in Maryland, included self-reports of favorite television show, amount of violence in that show, and respondent's violent…

This report describes the development and validation of the Weekly Activity Record (WAR), an instrument for the analysis and prediction of criminal behavior and recidivism. The 18 items on the instrument record the hours per week devoted to various activities: vocational, avocational, social, physical, antisocial, personal, and interpersonal. The…

The purpose of this study was to generate descriptive statistical estimates regarding the expected proportion of occurrence of each of the PROANA 5 (Process Analysis) variables (line usage, clique group, detrimental clique group, leadership, and dominance) in small group communication. A second purpose was to determine the expected pattern of…
