Designed to discriminate Negro dialect speech from standard English, the Rystrom Dialect Test seeks to overcome three problems encountered in research about Negro speech; determining what stable elements distinguish Negro dialect from standard English, constructing a test easily administered to a young child and capable of measuring the…

While the WISC and Bender-Gestalt are widely used for differential diagnosis, there is a need for empirically determined criteria for classification. Multivariate techniques seem especially promising in classification problems. This study determined the extent to which such an approach can classify children into rational, a priori categories of…

Several alternative indexes of item usefulness were empirically compared. They were: (1) item discrimination based on high and low groups on a postinstructional measure, (2) shift in item difficulty from a pre- to a postinstruction measure, and (3) item discrimination based on pre- and posttest performances. A typical classroom final examination…

A SPECIAL TRAINING PROGRAM IN SIZE DISCRIMINATION WAS STUDIED AS A MEANS FOR TEACHING REGULAR TRISOMIC MONGOLOIDS. BASED UPON THE SUCCESS OF THIS PROGRAM, A FURTHER ASSESSMENT WAS MADE AS TO ACQUIRED SIZE DISCRIMINATION ABILITY OF SUCH PERSONS WHEN TRANSFERRED TO OTHER LEARNING TASKS WITH PICTORIAL MATERIALS AND THREE-DIMENSIONAL OBJECTS. THE…

The power of the classical Linear Discriminant Function (LDF) is compared, using Monte Carlo techniques with five other procedures for classifying observations from certain non-normal distributions. The alternative procedures considered are the Quadratic Discriminant Function, a Nearest Neighbor Procedure with Probability Blocks, and three density…

This study used discriminant analysis to investigate the direction and intensity of student, parent, and school personnel attitudes, as measured by the Adjective Rating Scale (ARS), toward two college courses being offered in their high schools. (Author)

Variables from five domains--demography, social background, service history, satisfaction, and performance--were used in a discriminant analysis approach to distinguishing three groups of naval personnel. Potential usefulness of this method, including implications for better understanding and control of manpower turnover were discussed. (Editor)

Discriminant function analyses involving two vocational interest inventories to differentiate majors of college graduates supported the definition of three dimensions: Business Contract vs. Science, Business Detail vs. Arts, and Service vs. Technical. The implementation of such a three-dimensional scheme for counseling high school students is…

Survey data were collected from Illinois pharmacists to assess interest in an PharmD program. A discriminant analysis showed how employer support, reasons for participation, personal commitment and demographic characteristics contribute to explaining group variance of likely participants. It was found that external program design factors would be…

Eight randomly equivalent samples of high school seniors were each given a unique form of the ACT Assessment Mathematics Usage Test (ACTM). Signed measures of differential item performance (DIP) were obtained for each item in the eight ACTM forms. DIP estimates were analyzed and a significant item category effect was found. (Author/LMO)

In 1984 the American Association of Colleges of Pharmacy recommended that each college of pharmacy have curricular and training structures that provide for the education of "differentiated pharmacists." The University of Arizona examined whether the proposed options of clinical, management, and research would appeal to three different…

A discriminant function analysis identified variables that significantly differentiated bulimic (N=71) from nonbulimic (N=71) adolescent females within a high school setting. These variables included disturbed eating attitudes, negative perception of weight and body image, depressive symptomatology, and alcohol use. Implications for the etiology…

A discriminant analysis of objective and subjective measures from the records of students who graduated from the University of Medicine and Dentistry of New Jersey-New Jersey Medical School over a six-year period was used to generate a model for the prediction of medical specialty choice. (Author/MLW)

Using discriminant analysis, factors influencing teacher attrition were studied using three groups of University of Michigan graduates with teaching certificates: (1) those who taught continuously; (2) those who left teaching within five years; and (3) those who never taught. Implications for school administration, teacher training, and further…

This document discusses how community colleges often under-utilize collected student data. For example, community colleges use student pre-college assessment data to place students in specific courses. The paper suggests that student data can also be used to predict academic success (a grade of A, B, or C) in community college courses. Some of the…
