Two approaches to interest inventory validation are considered. The choice between the two depends on the use being validated. The first approach assumes that interest inventories are to be used in predicting which occupations counselees will enter or prefer. The second assumes that interest inventories are to used in suggesting occupations for…

This paper zeroes in on a subset of descriptors and predictors of undergraduate success, namely those which are neither cognitive measures (such as, high school grade point averages or aptitude test scores) nor personality test variables. The descriptors and predictors considered are broadly classed as: high school related; family and peer…

A stepwise canonical procedure, including two selection indices for variable deletion and a rule for stopping the iterative procedure, was derived as a method of selecting core variables from predictors and criteria. The procedure was applied to simulated data varying in the degree of built in structures in population correlation matrices, number…

A study was conducted to determine the relationship between grades received in prerequisite biology, chemistry, mathematics, and physics courses and subsequent average grades received in science major areas. Seven major areas were investigated. Subjects were students who graduated from the University of California, San Diego (UCSD), who had taken…

Applying techniques and statistical procedures of market research, this research paper treats the subject of environmental education. The first segment of the paper is involved with the identification of the role marketing can play in the analysis of environmental curricula and defines the potential market for environmental education. Sampling…

A Vocational Pattern Index, based on Zytowski's (1969) postulates on women's vocational participation, was developed. This index is based on age of first entry into the job market, number of entries, years of work, and degree of participation. Fifteen years after graduation from the University of Minnesota, a Questionnaire requesting detailed…

The purpose of this paper is to demonstrate the use of the general linear model (GLM) in problems with repeated measures on a dependent variable. Such problems include pretest-posttest designs, multitrial designs, and groups by trials designs. For each of these designs, a GLM analysis is demonstrated wherein full models are formed and restrictions…

Five structural, four linguistic and twelve topic variables are used in regression analyses on results of a 50-item achievement test. The test items are related to 12 topics from the third-grade mathematics curriculum. The items reflect one of two cases of the structural variable, cognitive level; the two levels are characterized, inductive…

The purpose of this study was to determine the relative effectiveness of the College Entrance Examination Board (CEEB) Mathematics Achievement Test, Level I, as an instrument for placing students in beginning college mathematics courses. For this purppse it was compared with several other variables as predictors of success in the specific courses;…

Previous research studies have established that students' academic achievement can be directed from their self-concepts of academic ability and from selected characteristics of the learning environment. The present study provides evidence for the relationships between learning environments and academic self-concepts, and it demonstrates that, for…

This paper discusses Bayesian m-group regression where the groups are arranged in a two-way layout into m rows and n columns, there still being a regression of y on the x's within each group. The mathematical model is then provided as applied to the case where the rows correspond to high schools and the columns to colleges: the predictor variables…

The purpose of this study involving predicting academic success in a teacher education program was to determine the relationship among the following factors; scores on the Mooney Problem Checklist (MPC), Kuder Preference Record Vocational (KPSV), Survey of Study Habits and Attitudes (SSHA), American College Test (ACT), and National Teacher…

Double-entry expectancy tables are used to make admissions, guidance, or employment decisions based on two predictors. Examples of their use in showing relationships between high school and college performance are explained. The advantages of double-entry expectacy tables given are: (1) relative simplicity of preparation requiring no formal…

This study involved two phases: first when classification was based on the calibration sample, and second in a cross-validation setting. Computer-generated data were used. Results obtained from rules based on probabilities of group membership were compared for accuracy when classifying in the discriminant space and in the predictor variable…

Analysis of student responses in 1,200 undergraduate classes to a 40 item Course Evaluation Questionnaire yielded the following results. None of the eight demographic variables correlated .2 or higher with any of 30 items on course and instructor. Variables correlating .4 or higher with five preference criteria were: clarity of instructor's…
