A stepwise regression technique was used to analyze assessment data while taking differences in nonschool variables across districts into account. The primary purpose of this investigation was to determine whether the inclusion of quadratic and/or interaction terms in a regression model would improve the prediction of school district average…

Multiple sources of complications in the analysis of multilevel educational data are described with emphasis on the determination of a method of analysis that will provide accurate estimates of teacher/class effects even when there are systematic differences in within-class regressions of outcome on input associated with teacher/class…

This study involved the investigation of the differential validity hypothesis as it pertained to the disadvantaged college student. It evaluated, by means of a multiple regression analysis, the use of SAT scores (Math and Verbal) and the Nelson-Denny Reading Test as predictors of college success, as measured by semester grade point average, for…

This report explains why the Management Implications of Team Teaching (MITT) project chose multiple linear regression and path analysis to analyze through-time relationships among variables, and why it rejected repeated-measures analysis of variance (ANOVA) and difference scores over time. Project MITT examined governance and work structures for…

This is the second volume of a two volume study. The first volume examined the literature to identify authoring aids for developing instructional materials, and to identify information clearing houses for existing materials. The purpose of this volume was to develop a means for assessing the cost versus expected benefits of innovations in…

A search for better predictors of incomes of high school and college graduates is described. The accuracy of the prediction, implicit in the work of John R. Walsh of Harvard University, that the income differences in a given year are good indicators of income differences in future years, was tested by applying standard statistical procedures to…

The development of a predictive equation capable of explaining a significant percentage of enrollment variability at Florida International University is described. A model utilizing trend analysis and a multiple regression approach to enrollment forecasting was adapted to investigate enrollment dynamics at the university. Four independent…

This paper reviews issues pertaining to the relationship between child mortality and fertility and examines the fertility-mortality relationship of women who emigrated to Israel from various countries in Asia, Africa, and Europe and continued child bearing in Israel. Data from the 1961 Israel census of population is used. Among issues addressed in…

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…

The study of non-college-attending, male high school graduates examines vocational, general, and college preparatory high school curricula and certain post-school training opportunities to uncover differences in their effectiveness, either alone or in conjunction with post-school programs, in preparing youth for careers. Based on data from the…

This document presents a modified cohort survival model which can be of use in making enrollment projections. The model begins by analytically profiling an area's residents. Each person's demographic characteristics--sex, age, place of residence--are recorded in the computer memory. Four major input variables are then incorporated into the model:…

Before implementing a course in the analysis of variance (ANOVA) taught through multiple linear regression, several concerns must be addressed. Adequate computer facilities that are available to students on a low-cost or cost-free basis are necessary; also students must be able to meaningfully communicate with their major advisor regarding their…

Population projections developed by the Pennsylvania Department of Education, 1970 to 2000, have been updated to report the latest information on fertility and mortality trends and migration within the State. Methology utilized closely resembles the cohort component procedure, with multiple regression analysis applied to historical information for…

This study seeks to illuminate those characteristics of students which predict their performance in using evidence to test a hypothesis. The research is conceived as part of a larger investigative strategy for understanding the relationships among characteristics of students, characteristics of social studies thinking tasks, and characteristics of…

This paper is an extended series of appendices to the report "Exploring the T.R.Q.: An Assessment of the Effectiveness of the Teachers' Rating Questionnaire," Report Number 123. It should be most useful to those familiar with multiple regression analysis and factor analysis and wishing a more complex record of the statistical procedures…
