The following models which provide an estimate of the reliability of a rating scale are described: (1) disattenuation; (2) common factor; (3) external criterion; (4) treatment effects; and (5) regression. Such models are especially useful in selecting, evaluating, and training participants in clinical research. (SLD)

In the South African context, the schooling returns of young African males aged 20-29 increased significantly between 1975 and 1985, whereas the returns enjoyed by older African males improved only negligibly. This paper shows that an improvement in schooling quality for Africans between the early sixties and early seventies partly explains the…

Multiple regression analysis is discussed as useful for studying the effect of a variable while controlling for the effects of others and for estimating the total effect of all predictor variables together. It is suggested that in English-as-a-Second-Language proficiency measurement, regression coefficients should not be the basis for judging…

Investigates the principal's instructional manager role, its relationship to student achievement, and how principals influence teachers to increase student learning. Subjects included elementary school principals and teachers in 27 schools. Student achievement was measured by regression analysis. Principal instructional management behavior was…

Using data from a class action suit at the University of Minnesota, this paper shows the different costs arising from paying women a percentage increase on their actual salaries, versus paying them predicted salaries as if they were men. The political consequences of enacting these different equalization methods (without additional funding) are…

A discussion of use of multiple regression to analyze faculty salaries, specifically for job discrimination litigation, concludes that, although appropriate regression studies may not win a case, their deficiencies or absence can lose one. In addition, the more complex the salary structure, the more useful regression analysis can be. (MSE)

Two distinct multiple regression models used in evaluation methods of the Dallas (Texas) public schools are discussed along with the issues and problems related to their application to the practical problem of identifying effective schools. Results from application of these models, one implemented in 1984 and one in 1992, are discussed. (SLD)

A general structural equation model for measuring residualized true change and studying patterns of true growth or decline is described. This approach allows consistent and efficient estimation of the degree of interrelationship between residualized change in a repeatedly assessed psychological construct and other variables. (SLD)

A meta-analysis of 21 instructional treatments aimed at enhancing the skill of deliberately deriving word meaning from context during reading shows a medium effect size of 0.43 standard deviation units. Exploratory multilevel regression shows that clue instruction appears more effective than other instruction types or practice alone. (Author/SLD)

Presents an opinion on the appropriate use of significance tests, especially in the context of regression analysis, the most commonly encountered statistical technique in education and related disciplines. Briefly discusses the appropriate use of power analysis. Contains 47 references. (Author/SV)

Exploring cognitive school leadership elements, this study uses a set of 1200 U.S. principals and employs an earlier validated set of five leadership cognitions drawn from psychologists in educational administration. Regression analysis suggests these cognitions exist independently of many social and personal qualities typifying principals and are…

Examines effects of prevailing wage laws on school construction costs, using final cost data from six British Columbia school districts. When controlling for factors such as construction business cycle, number of competitors, and school type, there was no significant unit cost change following the Skill Development and Fair Wage Policy Act.…

Investigates the relationship among principal leadership power; teacher empowerment; teacher compliance; and conflict within self, with peers, and with the principal, based on a survey of 250 teachers. Factor analysis and regression analysis revealed a strong association for expert power and referent power with each conflict dimension and teacher…

Explores the use of quantitative EEG in the detection of lies employing a special electrode cap and specialized video recording and audio equipment. The method offers the ability to decide when it can predict accurately and when it can predict with 100% accuracy. (JPS)

Discussion of the use of Latent Semantic Indexing to determine relevancy in information retrieval focuses on statistical regression and Bayesian methods. Topics include keyword searching; a multiple regression model; how the regression model can aid search methods; and limitations of this approach, including complexity, linearity, and…
