In the case of success-failure predictions, approximately 75 percent of those predicted to succeed did and 51 percent of those predicted to fail failed. (Editor)

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…

Factor scale scores are sometimes used as weights to create composite variables representing the variables included in a factor analysis. If these composite variables are then used to predict some dependent variable, serious theoretical and methodological problems arise. This paper explores these problems and suggests strategies for circumventing…

Although the decennial census provides poverty figures for states and other subnational geographic units, their utility declines over the course of a decade, causing interest in producing postcensus estimates for a variety of indicators. This study extends recent efforts to estimate postcensus poverty figures for states using multiple regression…

Assesses predictors of teachers' responsible environmental behavior (REB). Stepwise multiple-regression analysis showed that most of the parsimonious set of predictors of REB for all teachers included perceived knowledge of environmental-action strategies (KNOW), intention to act (IA), and perceived skill in using environmental-action strategies…

The concept of student engagement is receiving increased attention from researchers, higher education leaders, and the general public in recent years. This increased attention represents a shift from the more traditional "resource and reputation" model of academic quality to a model that emphasizes institutional best practices and student…

The purpose of this study was to examine age and competitive level differences in the relationship between determinants and level of sport commitment. Gymnasts (N = 304) comprised three age groups (8-11, 11-14.5, and 14.5-18 years) and two competitive levels (Levels 5-6 and 8-10). Multiple regression analyses revealed: (a) perceived costs and…

Student affairs professionals in the United States were surveyed to determine the predictive value of overall job satisfaction, organizational support, organizational politics, and work/nonwork interaction on affective organizational commitment. Results indicate that a supportive work environment leads to increased affective attachment to the…

The authors examined state dependency on depression, trait stability, and state-trait characteristics of perfectionism in a short-term longitudinal study of university students. Relative stability of perfectionism was assessed with test-retest correlations across 3 time points, and results showed higher rank order and relative stability for…

The value of variance is emphasized, and the element of design, frequently not adequately understood, is clarified to underscore the importance of variance to the researcher. Two analytic methods, analysis of variance (ANOVA) and multiple regression, are discussed in terms of how each uses/applies variance. Advantages and major difficulties with…

This study reports the results of research on analyses of game difficulty. Predictor variables were number of rules, spaces, and pieces necessary to play a game. Criterion variables were related to the child's ability to play successfully, and numbered eight. Data were subjected to multiple regression analysis, leading to the conclusion that it is…

Four computer programs using the general purpose multiple linear regression program have been developed. Setwise regression analysis is a stepwise procedure for sets of variables; there will be as many steps as there are sets. Covarmlt allows a solution to the analysis of covariance design with multiple covariates. A third program has three…

This paper presents the results of three experiments studying routine problem-solving tasks in simple addition and subtraction. Indications are that children tend to solve such problems by internalized counting procedures which may be learned independently as a consequence of practice in problem solving. Brief descriptions of exploratory studies…

Part 1 of a two-part article describing a study that attempts to identify determinants of change in teacher salaries and examines both school district contextual factors and school district negotiations characteristics in terms of final contracts negotiated in New York during the 1971-72 school year.

This study, based on a survey of rural families in several provinces in Indonesia, is an attempt to search for variables, and combinations of variables, that predict the actual utilization of schooling by individual families. Suggests these useful predictors: family characteristics, family economic status, family orientation toward education.…
