It is widely known that the presence of multicollinearity in a dataset can have detrimental effects on determining which predictors are responsible for the variation in the response (e.g. Pedhazur, 1982). There also exist some indication that the presence of multicollinearity does not impact one's ability to accurately estimate/predict the value…

This research connects several data-driven educational data mining approaches to a framework for interaction developed in educational research. In particular, 10 million usage data points collected by a Learning Management System used by students and teachers in 450 online undergraduate courses were analyzed with this framework. A range of…

The purpose of this study was to explore connections among perceived caring climate, empathy, and student social behaviors in high school bands. Nine high school band directors (N = 9 schools), along with their students (N = 203), completed an electronic questionnaire for variables of caring climate, cognitive empathy, affective empathy, social…

Problems encountered in teaching multiple linear regression forecasting are described, and methods of dealing with such problems are outlined. Problems discussed include: (1) the irrelevance of instructional exercises, (2) data base sizing as a major area of regression "unreality", (3) difficulties in locating or using actual data, (4) neglect of…

A Monte Carlo study was conducted to estimate the efficiency of and the relationship between five equations and the use of cross validation as methods for estimating shrinkage in multiple correlations. Two of the methods were intended to estimate shrinkage to population values and the other methods were intended to estimate shrinkage from sample…

The prediction that differences in incomes of high school and college graduates will not change is tested by applying standard statistical procedures to data describing actual income differences. Data from the United States Bureau of the Census describe annual incomes of men twenty-five years old and older during 1956-75. Report 1 displays results…

Classical multiple regression was compared with Bayesian m-group regression, complete with cross-validation. The setting was a post-developmental studies situation in a comprehensive community college. A secondary purpose of the study was to incorporate an advisor prediction of grade point average (GPA) as input into both regression procedures.…

An incentive pay plan for teachers was implemented in the Houston (Texas) Independent School District in the 1979-80 school year. The "outstanding educational progress" (OEP) component of the plan was based on student performance on standardized tests. Schools were grouped to allow students of similar socioeconomic backgrounds to be…

Taxing situations that threaten the administrator's sense of self-efficacy meaningfully account for burnout in human-service professionals. This paper presents findings of a study that hypothesized that environmental or role stressors could be classified as task, organization, and relations stressors, each pertaining to a different domain of the…

Data from the High School and Beyond study--restricted to over 800 regular public school students from a population of 18,684 who completed test batteries in both their sophomore and senior years--are analyzed in this report. Included in the cluster of 12 school variables are school policies, school resources, and school practices. The…

Technical considerations in the development of a salary equity model based upon regression analysis are reviewed, and a simplified salary prediction equation is examined. Application and communication of the results of the analysis within the existing operational context of a postsecondary institution are also addressed. The literature is…

This study was conducted in an attempt to identify any predictor or combination of predictors of a beginning typewriting student's success. Variables of intelligence, rhythmic ability, musical background, and tapping ability were combined to study their relationship to typewriting speed and accuracy. A sample of 109 high school students was…
