Westbrook (1983) challenged the validity of the construct "career maturity" because measures such as the Career Maturity Inventory Attitude Scale (Crites, 1973) correlate to measures of mental ability. Rather than interpreting this association as evincing lack of discriminant validity, the association should be interpreted as supporting…

It is the purpose of this paper to investigate the chance nature of overfit as it relates to a regression formulation of research, to describe a model for projecting the overfit, and to empirically validate the model. (Author)

Article identified important variables where concentrated efforts can be made for the improvement of cognitive achievement of Indian children. (Author/RK)

The aim of this research was to increase understanding of the relationship between family variables and measures of child welfare. Conclusions were that welfare status is not explained by the use of individual measures on their own. (Author)

Data from 212 students were collected as part of a study of factors that contribute to academic success in introductory college-level speech communication courses. Nine noncognitive predictor variables were included: speech experience, absence of speech anxiety, four indicators of aspiration/performance consistency, and three demographic…

This paper considers the case of two predictor variables. Figures are obtained which show the regions of significance of joint regression coefficients, regression coefficients considered separately, and the multiple correlation. The intersection of these regions of significance and non-significance illustrates how the various apparent…

Score on the Mathematics Test of the National Teacher Examinations (NTE) was the dependent variable in a stepwise multiple regression using personological variables of in-service teachers as regressors. Two variables--number of semester hours credit in mathematics, and grade level of teaching--accounted for 61 percent of the observed NTE score…

This is one of a series of brief and non-technical mini-reports of the Evaluation System of the District of Columbia Public Schools. This report deals with the prediction of gain in Prescriptive Mathematics Test (PMT) scores. Twenty-two variables were involved in the analyses reported in the mini-report. The data were analyzed for all grade…

A procedure for rapid screening of variables as potential moderators is presented and discussed. A moderator is defined as any variable which can be used to identify differentially predictable persons; or defined statistically by stating that if a predictor and a moderator are each divided into three or more categories and used as independent…

Two hypotheses were developed in an attempt to organize and clarify the conceptual basis for studies of relationships between patterns of habitual sleep duration and self-perceptions of the need to achieve. A non-specific arousal (N-SA) hypothesis presumes that short sleepers show more vigor, more general anxiety, incline more toward development…

The utility of a non-linear transformation of the criterion is established. The Pythagorean Theorem is used as the example to demonstrate the point. The functional relationships may be such (as in the Pythagorean Theorem) that an R-squared of 1.00 cannot be found without making a non-linear transformation of the criterion. The goal of…

Observations during research involving the Bruce Treadmill Test (BTMT) indicating that Stage III for females and Stage IV for males represented speeds which are intermediate between comfortable walking and confortable jogging for many subjects, prompted this study to determine ways to obtain more consistent group results. Twenty-eight subjects…

Adolescent coital activity and the attendant risk of pregnancy is a problem with far-reaching implications. The aim of this study was to investigate the influence of family variables on adolescent sexual behavior and contraceptive practices. More specifically, the research question was: Could a set of parent-adolescent interpersonal variables be…

This study assessed the effect of factors outside the instructor's control on student ratings of instruction. Seven special items along with the standard Student Ratings forms were administered to 28 classes in the Anthropology Department. Results indicated that the impact of outside factors, as perceived by students, was not correlated with…

Prediction for a number of criteria from a set of predictor variables in a system of regression equations is studied with the possibilities of linear transformations applied to both the criterion and predictor variables. Predictive composites representing a battery of predictor variables provide identical estimates of criterion scores as do the…
