Education researchers often study count variables, such as times a student reached a goal, discipline referrals, and absences. Most researchers that study these variables use typical regression methods (i.e., ordinary least-squares) either with or without transforming the count variables. In either case, using typical regression for count data can…

This study investigates the predictors of school practitioners' (N = 2,425) use of educational research. The suggested model explained significantly but modestly the infrequent use of educational research by practitioners. Of the four factors in the study, "opinions about research" had the most explanatory power. The results are…

In gifted education research, it is common for outcome variables to exhibit strong floor or ceiling effects due to insufficient range of measurement of many instruments when used with gifted populations. Common statistical methods (e.g., analysis of variance, linear regression) produce biased estimates when such effects are present. In practice,…

Although access to a postsecondary education has increased exponentially since 1970, access to a bachelor's degree has not grown as swiftly. Moreover, while national longitudinal trend data highlight improvements in bachelor's degree completion in the aggregate, they disguise important disparities in bachelor's degree completion across groups.…

Addresses the use of missing cells in longitudinal research. Gives a sample educational situation involving cohorts and grade levels and uses multiple linear regression for the solution. Discusses applications of longitudinal research wherein logically missing cells occur. (Author/SV)

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)

This paper presents a number of inferential statistical models that may aid the operant investigator in presenting his data. (Author/RK)

Three procedures are examined that educational researchers can use to analyze quantitatively the extent to which modifications of specific teacher behaviors lead to changes in student achievement. The task requires decent descriptions of the behaviors, appropriate statistical tools and measures of student outcomes that are worth while examining.…

A simulation model of a suburban school district is synthesized by incorporating the results of multiple regression analysis within an Industrial Dynamics framework. The intermediate empirical analysis is described and results of the validation procedure for the final simulation model presented. Three computer experiments with the system model are…

This paper examines the multivariate multiple regression model and explores its applicability to communication research. The first section discusses partitioning of a data matrix, as a heuristic device for distinguishing among alternative regression models. Section two examines various aspects of univariate multiple regression, including the form…

This report analyzes the results of research into the relationships between such inputs as expenditure per pupil and school district size and the average achievement of pupils in basic subjects. The analysis focuses on production function relationships of education. The results of the analysis illustrate the problems involved in constructing…

A strategy is proposed for dealing with educational research problems, using as an example a study based on data that had already been collected and using that data to discover how differences in school characteristics may result in differences in their students. The research method is based on concepts of analysis of covariance and is concerned…

Latent abilities of dental students were analyzed as causes and professional achievements as effects, with preadmission performances as indicators of latent abilities. The results demonstrate that structural analysis focuses on the direct impact of the quality of dental school education. (Author/MLW)

This study was undertaken to compare the variables related to the successful institutionalization of changes across divergent organizations, and to design, through cross-validation, an interorganization model of change. Descriptive survey questionnaires and structured interviews were the instruments used. The respondent sample consisted of 1,500…

Research investigated: 1) the effect of instructional mode on student achievement; 2) the relationship between a) the student factors of aptitude, sex, previous achievement, educational level, and academic major and b) achievement; and 3) the possibility of a homogeneity of regression equations for achievement of students in varying instructional…
