Three methods of transforming unordered categorical response variables are described. One is a method using dummy binary variables. The second method analyzes all categorical variables simultaneously and is based on an eigenanalysis of frequency patterns scaled relative to within-groups variance, jointly developed by J. E. Overall and J. A.…

This paper focuses on three aspects related to the conceptualization and application of canonical correlation analysis as a dominant statistical model: (1) partial canonical correlation analysis and its application in statistical testing; (2) the relation between canonical correlation analysis and discriminant analysis; and (3) the relation…

Presents a microcomputer-based qualitative discriminant process (QDP) for scoring and ranking in group support systems that is relevant to group decision-making situations that involve the evaluation of alternatives. Scoring and ranking techniques are described, and a case illustration using the QDP is discussed. (Contains 50 references.) (LRW)

A method is described by which cognitive structures in verbal data can be identified and categorized through numerical analysis and quantitative description. Transcriptions of interviews (in this case, the verbal statements of 40 researchers) are manually coded and subjected to analysis following the AaO (Agent action Object) paradigm. The texts…

Individualized instruction programs have imposed an increased reliance on tests as a means of selecting and routing students through sometimes complex programs. Testing which occurs within the training sequence is particularly vulnerable to inefficient use of both trainee and instructor time, but computer-based instruction system can provide a…

The general objectives were to develop and implement computer-based procedures for obtaining validated data on the characteristics of vocational school students, and to convert this data into counseling information. To do this, two types of data information conversion procedures were used: discriminate analysis and regression analysis. Scores from…

Information from tests, when considered in the context of decision theory, can play an important role in vocational development. This role is primarily one of stimulating and facilitating exploratory behavior. Objective procedures for converting test data into counseling information are discussed and illustrated with special attention being given…

This study represents classroom observations of a secondary school which employs ability grouping for grades seven through twelve. The effects of ability grouping on the interaction in the classroom was measured with use of Flanders Interaction Analysis. Two history teachers with identical grades and phases were used in this study which began in…
