Correlation and multiple regression analyses revealed the extent to which the report card grades of Quality Counts 2002, prepared by Education Week, were intercorrelated with and predicted by demographic factors among many states. The researchers used four grades from Quality Counts 2002 and five demographic factors. Few intercorrelations were…

Many measures found in educational research are ordered categorical response variables that are empirical realizations of an underlying normally distributed variate. These ordered categorical variables are commonly referred to as Likert or rating scale data. Regression models are commonly fit using these ordered categorical variables as the…

This study was performed to determine whether hierarchical logistic regression models could reduce the sample size requirements of ordinary (nonhierarchical) logistic regression models. Data from courses with varying class size were randomly partitioned into two halves per course. Grades of students in college algebra courses were obtained from 40…

This Monte Carlo study explored relationships among standard and unstandardized regression coefficients, structural coefficients, multiple R_ squared, and significance level of predictors for a variety of linear regression scenarios. Ten regression models with three predictors were included, and four conditions were varied that were expected to…

This manuscript summarizes an institutional research study carried out at Bowling Green State University (BGSU) concerning factors affecting time to bachelor's degree attainment. Tuition sensitivity and concern about efficient use of institutional resources point to the need for decreasing students' time-to-degree. This study enlarges upon an…

Because ignoring the missing data in an evaluation may lead to results that are questionable, this study investigated the effects of use of four missing data handling techniques on a survey instrument. A questionnaire containing 35 5-point Likert-style questions was completed by 384 respondents. Of these, 166 (43%) questionnaires contained 1 or…

This study showed that almost all of the students brought calculators to the administration of the SAT I test in November 1996 and 1997 and continue to do so today. The number who actually used the calculators on the test and the extent to which they used them varied across students. Performance on the math sections of the exam was associated with…

A series of comments, corrections, and errata are presented regarding homogeniety of regression (see also EJ 001 198). (CK)

This paper demonstrates that gain score analysis and analysis of covariance (ANCOVA) will always yield conflicting results unless the slopes of within-group regression lines of posttest on pretest equal one. In Lord's specific hypothetical example, trait instability invalidates the ANCOVA. An analysis that corrects for this problem is…

Tested the utility of the Personal Orientation Inventory (POI), the Myers-Briggs Type Indicator, and the Girona Affect Scale in predicting the outcomes of a marathon Gestalt therapy workshop. Signigicant predictive equations were generated that use the POI to predict gains on the Girona Affect Scale. (Author/RC)

Describes the use of programs written in BASIC and graphics facilities of microcomputers to make students aware of the assumptions of statistical models in linear regression and the design of experiments. Two references are cited. (CHC)

Reports on a five year study of 82 large academic libraries which found that both interlibrary loan lending and borrowing are correlated to collection size. (RBF)

Applications of moderated regression analysis in five areas of job design research are described and fully illustrated with actual survey data. Moderated regression analysis was superior to a subgroups analysis for the research questions being asked by investigators interested in job design research. (Author)

The present study compared six methods, two of which utilize the content structure of items, to estimate total-test scores using 450 students and 60 items of the 110-item Stanford Mental Arithmetic Test. Three methods yielded fairly good estimates of the total-test score. (Author/RL)

Regression equations were formulated to determine the predictability of the College Level Examination Program performance from ACT scores. Equation strength prompted further investigation to determine if a relationship could be established. The tally matrix from which probabilities were computed was found to be effective for predictive purposes.…
