This study developed and investigated an empirical sampling distribution of the congruence coefficient. The effects of sample size, number of variables, and population value of the congruence coefficient on the sampling distribution of the congruence coefficient were examined. Sample data were generated on the basis of the common factor model and…

The mixed model analysis of variance assumes a mathematical property known as sphericity. Several preliminary tests have been proposed to detect departures from the sphericity assumption. The logic of the preliminary testing procedure is to conduct the mixed model analysis of variance if the preliminary test suggests that the sphericity assumption…

The stepwise regression method of selecting predictors for computer assisted multiple regression analysis was compared with forward, backward, and best subsets regression, using 16 data sets. The results indicated the stepwise method was preferred because of its practical nature, when the models chosen by different selection methods were similar…

The purpose of this paper is to demonstrate how multiple linear regression provides a viable statistical methodology for dealing with meta-analysis in general, and specifically with the issues of nonindependence and design complexity, such as multiple treatments. Since the F-test and t-test are special cases of the general linear model,…

Meta-analysis has become an important supplement to traditional methods of research reviewing, although many problems must be addressed by the reviewer who carries out a meta-analysis. These problems include identifying and obtaining appropriate studies, extracting estimates of effect size from the studies, coding or classifying studies, analyzing…

This study was undertaken because of a sharp dip in the increase rate in post-secondary enrollments in Manitoba for Fall, 1970. Research was carried out to examine the process by which Manitoba's twelfth grade students make decisions concerning post-secondary enrollment. The research provides information on students' career plans, post-secondary…

Research into the area of assessment of post-secondary demand by Manitoba high school students began in 1971, when a sudden drop in the increase rate of post-secondary enrollment was observed. This report is one of a series that has been published based on the high school demand studies. Earlier reports were largely statistical in nature, and…

Utilized a sample randomly drawn from an approximated population of 1,819 eighth grade classes. Analyzed were class levels of consistency within response sets, paired comparisons, and triad comparisons. (GS)

To find out what happens to a major segment of the working population over several years, the Manpower Administration is sponsoring a 10-year study on the work lives of middle-aged men. The article discusses data from a monograph reporting the completion of the first half of the study. (Author/AJ)

This research memo presents the 1979-80 update of the Composite Indicator of Changes (CIC), a statistical measure for gauging and comparing changes in average salaries and wages paid to public school employees. The CIC offers a measure for analyzing salary trends in an individual school system and within groups of school systems, and with other…

A study was done on teachers, professors of education, and preservice teachers in order to investigate the process of measuring attitudes and to denote the level of attitudes held by these educators about the free enterprise system. The study used a semantic differential to determine the attitudes of 28 subjects toward selected economic concepts…

Successful curriculum implementation depends partially on agreement between developers and teachers regarding the relative importance of the objectives of the program. This paper analyzes the ratings of the relative importance of various stated objectives of an elementary science unit by developers, teachers, and outside evaluators. The rating…

A solution is proposed for analysis of variance procedures with missing cells, such as may occur when a control group is not assigned to any of the rows or columns of the various experimental groups. Mathematical models for two-way design are presented which define several variables; as well as row effect, column effect, and row and column…

The purposes of this study were to compare the responsiveness of educational expenditures per pupil in Ontario, first, to changes in instructional expenditures per pupil during 1971-77, and, second, to changes in proxy measures of educational quality and price levels of teacher services for 1974-77. Variables used to represent quality and price…
