In contrast to linear models of human judgment developed for predictive purposes which are characteristically insensitive to the exact values of the weights utilized in them, the Linear Multiple Regression Models used for policy capturing are assumed to reflect significant aspects of the subjects' judgmental policies. This latter kind of modelling…

The relationships between a diverse set of individual difference, demographic, and aptitude variables; and a set of student attitudes and behaviors pertinent to experiences in large lecture classes were examined. The sample was 4300 students enrolled in 33 lecture classes at a large university. The relationship between the set of individual…

This paper considers the application of Bayesian techniques for simultaneous estimation to the specification of regression weights for selection tests used in various technical training courses in the Marine Corps. Results of a method for m-group regression developed by Molenaar and Lewis (1979) suggest that common weights for training courses…

Self-selection bias poses a major threat to the validity of research findings in naturalistic, quasi-experimental, or single-group designs. A new method of addressing self-selection bias in naturalistic evaluations of prevention programs was implemented. The study, involving voluntary exposure to multicomponent interventions, was developed and…

This study used data collected during 1981-82 from a random sample of 1,960 9-year-old students from 124 elementary schools involved in a national assessment of educational progress in science. The database was used in secondary analyses which probed the validity of a model of educational productivity involving a set of nine aptitudinal,…

The utility of a theoretical model of quality of life for graduate students was investigated. Variables that relate to the person-environment fit of graduate students were also examined. The data were collected via a biographical data form and seven psychometric instruments. The 142 subjects from two graduate departments at Peabody College were a…

The effects of synchronous and asynchronous lectures and interaction formats were examined with graduate business students in on-campus and off-campus MBA programs. The dependent variables were scores on exams questions and learning styles and cognitive styles were used as covariates. The results indicated significant differences for discussion…

This study tests the relationship between a set of predictor variables that offer a possible explanation of communication apprehension and a set of criterion variables closely associated with communication apprehension. The predictor variables, emerging from "the double-bind theory of communication," which is concerned with the pathology-producing…

This study examined the relationship between observed classroom behavior (teacher-pupil interactions) and reading achievement. An elementary school reading teacher and six students with different coping styles were observed six times in each of 41 classrooms during the school year. Pretest and posttest reading scores, a measure for socioeconomic…

This paper examines the multivariate multiple regression model and explores its applicability to communication research. The first section discusses partitioning of a data matrix, as a heuristic device for distinguishing among alternative regression models. Section two examines various aspects of univariate multiple regression, including the form…

This study was conducted to identify student and tutor variables related to student progress in a structured summer reading tutorial program. High school and college students and adults tutored individually 121 elementary and junior high school students for six weeks. Criterion variables were number of tutoring books completed, residual gain…

In the spring of 1977, the University of Washington Faculty Senate revised the undergraduate admissions system to include equitable means for admitting freshmen and transfer students. Generally, the University adopted the position that it is the best qualified individuals who should be admitted, with best qualified being defined as those having…

Noting that the practitioner is confronted with conflicting definitions of "fairness" that claim to avoid "bias" in test usage, this article asserts that "mean fairness" can be achieved by use of multiple regression with the dichotomous variate, group membership, included as a predictor; mean fairness also holds for sub-groupings, based on test…

Relationships between the ratings of interns by their supervisors, their peers, and the interns themselves on four dimensions are compared and analyzed in relationship to earlier measures of aptitude, achievement, and personality. Findings reported show supervisor ratings to be highest and admission variables to be unrelated to intern performance.…

The importance of reading in a course (content, evaluation, etc.) needs to be considered. This research involved 120 college students and compared the Revised Nelson-Denny reading scores (vocabulary, comprehension, rate) and a course grade. Questionnaire responses were also received. Vocabulary predicted about 35 percent of the grade variance.…
