COLLEGE OBJECTIVES WERE REDEFINED AND STUDENT CHANGE EXAMINED TO DETERMINE WHETHER--(1) STUDENTS CHANGE IN COLLEGE, (2) WHEN AND WHERE CHANGE OCCURS, AND (3) DEVELOPMENTAL PRINCIPLES WHICH COULD APPLY TO STUDENT CHANGE TO FACILITATE DECISIONS. DEFINITIONAL ACTIVITIES YIELDED SIX MAJOR SUBCATEGORIES OF BEHAVIORS AND STUDENT CHARACTERISTICS--GOAL…

Sixteen Personality Factor Questionnaire (16 PF) profiles for 69 occupational groups were analyzed according to Holland's six occupational types: Realistic, Investigative, Artistic, Social, Enterprising, and Convention. Three discriminant functions, labeled Independence, Extraversion, and Anxiety, enabled correct classification of 75 percent of…

Describes a criterion group classification scheme commonly used in conjunction with discriminant function analysis and suggests that clinicians consider membership probabilities for each criterion group of interest. Illustrates this approach using data from a study in which discriminant analysis was used to identify characteristics of problem…

A methodology developed as an alternative to conventional institutional classification structures, intended to reduce the limitations of those models, is described. Ways in which the methodology can be used for planning, administrative, and research purposes are discussed, as are the dangers in using "peer groups" for institutional…

This study compares the classification accuracy of linear discriminant analysis (LDA), quadratic discriminant analysis (QDA), logistic regression (LR), and classification and regression trees (CART) under a variety of data conditions. Past research has generally found comparable performance of LDA and LR, with relatively less research on QDA and…

Domestic violence is an issue that affects different sides of society; numerous studies have shown that it is a problem that is increasing. This study used a discriminant analysis to identify those scales that might be more effective at predicting group membership among batterer types: pathological batterers, sexually violent batterers, generally…

This investigation is a comprehensive acoustic study of 4 voiceless fricatives (/f [theta] s [esh]/) in English produced by adults and pre-and postpubescent children aged 6-14 years. Vowel duration, amplitude, and several different spectral measures (including spectral tilt and spectral moments) were examined. Of specific interest was the pattern…

The purpose of this research is to develop content analytic techniques capable of extracting the differentiating information in narrative performance evaluations for enlisted personnel in order to aid in the process of selecting personnel for advancement, duty assignment, training, or quality retention. Four tasks were performed. The first task…

This study was conducted to evaluate the usefulness of discriminant analysis in classifying vocational and technical curricular groups in a single secondary school setting. The researchers compared scores on the Dailey Vocational Test and the Minnesota Vocational Interest Inventory in terms of the selection of vocational and technical courses by…

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…

Numerical classification techniques were used to explore the conjecture that inconsistent results of many studies of disabled readers could result from samples being composed of subgroups of children with different characteristics. Some five subgroups were identified using ITPA scores from a subsample of 37 poor readers. (Author)

Research attempted to establish the existence or lack of existence of an identifiable "rural culture" and to establish the presence or absence of an equivalence relationship between geographic residence and rural culture. A factor analysis of a wide range of attitudinal questions from the 1977 National Opinion Research Center (NORC)…

This paper is concerned with the identification and testing of salient variables which show potential for explaining client use of evaluation information. A single-page interview instrument was devised which aggregated the factors and factor categories collected following an extensive review of the literature. Data were collected from a…

Compared the efficacy of two methods of cluster analysis, the unweighted pair-groups method using arithmetic averages (UPGMA) and Ward's method, for students grouped on intelligence, achievement, and social adjustment by both clustering methods. Found UPGMA more efficacious based on output, on cophenetic correlation coefficients generated by each…
