The issues in the interpretation of discriminant analyses presented are restricted to the typical uses of discriminant analysis by behavioral science researchers. Because behavioral researchers use computer programs packages, the issues discussed deal with information obtainable from the package discriminant analysis programs. The following issues…

To better determine the cognitive abilities needed for computer programming, a study was done using 41 junior and senior level college students majoring in social and behavioral sciences at a Los Angeles area university. The subjects were first tested to determine their cognitive abilities with regard to spatial ability, field…

The advantages and disadvantages of three analytic methods used to analyze experimental data in educational research are discussed. The same hypothetical data set is used with all methods for a direct comparison. The Analysis of Variance (ANOVA) method and its several analogs are collectively labeled OVA methods and are evaluated. Regression…

The methods and approaches for estimating the operating characteristics of the discrete item responses without assuming any mathematical form have been developed and expanded. It has been made possible that, even if the test information function of a given test is not constant for the interval of ability of interest, it is used as the Old Test.…

Whenever one uses ordinary least squares regression, one is making an implicit assumption that all of the independent variables have been measured without error. Such an assumption is obviously unrealistic for most social data. One approach for estimating such regression models is to measure implied coefficients between latent variables for which…

The results of Seaver's (1973) quasi-experimental study of the effects of teacher expectancies on student achievement based on older sibling performance are reinterpreted as a regression artifact. That this rival explanation has not been recognized in the literature is probably due to the effects of researcher expectancies. (Author/BS)

This article presents lessons learned from an innovative employment and training program for dislocated workers. It provides specific information about program design and serves as a prototype for how social experimentation can be used by state and local governments. (Author/LMO)

Cognitive ability tests, personality inventories, and administrative- skills measures were administered to 238 telephone company employees. A small number of interpretively and predictively useful molar personal/motivational scales were derived using factor analysis. Some measures from each of the domains of the assessment battery were found to be…

Thirty-eight sixth-grade students participated in a study that examined the relationship of conceptual tempo and performance on several study and reading activities. Results indicate that conceptual tempo may have a relationship to effective studying and reading. Methodology and results are discussed. (Author/JL)

Presents a review of path analysis techniques using Hope's (1984) comparative study of schooling and social mobility in Scotland and the United States as a case study. Path analysis has been used in the social sciences to untangle complex cause and effect relationships. The limits of path analysis as a way to analyze complex social phenomena are…

A random sample of 108 Comprehensive Employment and Training Act (CETA) qualified probationers, enrolled in a job training program, were compared to a random sample of community probationers on arrest and conviction records. Both groups achieved a high degree of success, but no significant differences were found. Individual characteristics, rather…

Most organizational behavior literature recognizes the importance of guidance and good feelings (leader substitutes) in maximizing personal and organizational outcomes. In this study, teachers identified leader substitutes, not leader behavior, as significantly related to organizational commitment and role ambiguity. Includes 5 tables and 14…

Drawing on recently developed methodology for structural equation modeling with categorical data, this article proposes a new approach for investigating the behavior of dichotomously scored test items in relation to other relevant (observed) variables. A linear structural model relates the latent ability variable to a set of observed scores.…

The concept of change is related to suppressor variable conditions in a least square regression model. The domain of conditions necessary for a weighted change score composite to emerge as an underlying construct is mapped and the information loss through arbitrary assignment of weights to a change composite is explored. (Author/BW)

Data from surveys of university students that utilized the Approaches to Studying inventory were analyzed to test the hypothesis that a curvilinear relationship exists between learning strategies and academic grades. However, none of the non-linear regression models investigated improved significantly on the explanatory power provided by the…
