The problems and progress of a group of students designated as disadvantaged upon college entry and demographic factors that may be critical predictors of disadvantaged students' academic failure in a course are examined. Special advising and intervention are recommended, so that students need not take the initiative to seek help. (MSE)

Canonical correlation analysis is a multivariate statistical model which facilitates the study of interrelationships among multiple dependent variables and multiple independent variables. It identifies components of one set of variables that are most highly related linearly to the components of the other set of variables. The underlying logic of…

This report is about the problem of making transition or enrollment rate gains comparable. It is shown that measures based on the proportions themselves, i.e. the difference between proportions, the proportion ratio and the residual gain ratio do not make the gains comparable. Instead a non-linear transformation has to be done. Two such…

Three procedures used to control Type I error rate in stepwise regression analysis are forward selection, backward elimination, and true stepwise. In the forward selection method, a model of the dependent variable is formed by choosing the single best predictor; then the second predictor which makes the strongest contribution to the prediction of…

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 principal axes factor analyses were performed. (Author/LMO)

In research, data sets often occur in which the variance of the distribution of the dependent variable at given levels of the predictors is a function of the values of the predictors. In this situation, the use of weighted least-squares (WLS) or techniques is required. Weights suitable for use in a WLS regression analysis must be estimated. A…

Meta-analysis is a technique for combining the summary statistics from previously conducted research studies to indicate the direction of results and provide an index of the magnitude of effect size. This paper focuses on the effect of the violation of the assumption of independence (that the value of any included statistic is in no way…

A study was designed to investigate the possibility that college students who participate in career decision-making (CDM) programs differ from the general college population in ways unrelated to their CDM status. This exploratory hypothesis was tested by determining, first, whether a regression equation could be constructed using readily available…

The efficacy of a variety of selection measures in predicting successful performance in Air Force physician assistant training were investigated. Variables identified for the analysis of 51 subjects (graduates of the Air Force program) were: Scholastic Aptitude Test (SAT, combined verbal and mathematics composites), Airman Qualifying Examination…

A peer tutoring program in spelling was developed to investigate effects of several tutor and tutee characteristics on tutorial outcomes, amount of learning and learning efficiency. Examination of the data reveals only the tutee's pretutorial spelling score was a significant predictor of the amount of learning. (Author)

In this paper the bootstrap technique was applied to the evaluation of potential predictive bias for different ethnic groups using the Scholastic Aptitude Test (SAT) and high school ranks to predict college grade point averages (GPAs). Data of three ethnic groups were used; the total number of subjects was close to 5,000. Both conventional…

This paper is part of a series of applied statistics monographs intended to provide supplementary reading for applied statistics students. In the present paper, derivations of the unbiased standard error of estimate for both the raw score and standard score linear models are presented. The derivations for raw score linear models are presented in…

To predict the educational quality of programs in 150 school districts, this study used 34 predictor variables in a multiple regression analysis. Dependent variables used to represent educational quality in a district were (1) the percent of rejections by the local Selective Service Boards for mental reasons, (2) the percent of elementary and…

With the resurgence of interest in sex differences research, it is important to use a "confidence interval" strategy in organizing and interpreting material rather than a strategy of statistical significance or non-significance. Investigators are urged to go beyond the reporting of statistical significance and to determine something…

The report is concerned with the feasibility of matching people and jobs as proposed by the Theory of Work Adjustment; according to the third proposition of this theory, satisfaction is a function of the correspondence between the reinforcer system of the work environment and the individual's needs, with certain qualification. In the study, the…
