REPRESENTATIVE ORDERING AND SELECTION OF VARIABLES, VOLUMES A AND B--STATISTICAL MODELS FOR THE EVALUATION AND INTERPRETATION OF EDUCATIONAL CRITERIA, PART 3.
BARGMANN, ROLF E.
THE STUDIES EMBODIED IN THIS REPORT PROPOSE SOME STATISTICAL METHODS OF ORDERING AND ATTAINING RELEVANCY TO HELP THE EDUCATIONAL RESEARCHER CHOOSE AMONG SUCH VARIABLES AS TESTS AND BEHAVIOR RATINGS. CONSTRUCTION OF A MODEL FOR THE ANALYSIS OF CONTINGENCY TABLES, DETERMINATION OF THE MOST APPROPRIATE ORDERING PRINCIPLE IN STEP-DOWN ANALYSIS FOR THE QUALITATIVE INTERPRETATION OF STATISTICAL RESULTS, AND DEVELOPMENT OF STATISTICAL TESTS TO INTERPRET THE RESULTS WERE ATTEMPTED. PARTIAL CORRELATION AND PARTIAL ASSOCIATION CONCEPTS ARE ANALYZED TO DETERMINE PARAMETERS FOR GENERALIZING CLASSIFICATION OF DEPENDENCE PATTERNS. PROCEDURES WERE DEVELOPED FOR FACTOR IDENTIFICATION AND COMPARED WITH LATENT CLASS ANALYSIS PROCEDURES CURRENTLY IN USE. SUBJECT-TEST INTERACTION MODELS DESIGNED THROUGH OTHER RESEARCH WERE USED FOR COMPARISON. VARIANCE-COVARIANCE OR CORRELATION MATRIX PATTERNS RESULTING FROM EACH ASSUMPTION CONCERNING THE NATURE OF SUBJECT-TEST INTERACTIONS WERE PRESENTED. STATISTICAL TESTS WERE CONSTRUCTED FOR DETERMINING THE PLAUSIBILITY OF EACH PATTERN AND FOR PATTERN DIFFERENCES. SUBJECT-TEST INTERACTION MODELS WERE IDENTIFIED THROUGH THE DEVELOPMENT OF STATISTICAL METHODS, AND THESE METHODS WERE IN TURN TRANSLATED INTO OPERATIONAL PROCEDURES. IT WAS CONCLUDED THAT STATISTICAL INTERPRETATION OF SIGNIFICANT GROUP DIFFERENCES IS POSSIBLE USING DISCRIMINANT FUNCTIONS AND SUBSEQUENT STEP-DOWN ANALYSIS. ANY DIFFERENCES DUE TO LATENT ARTIFICIAL VARIABLES INSTEAD OF THE OBSERVED VARIABLES MAY BE DETERMINED THROUGH FACTOR AND DISCRIMINATION ANALYSES. OTHER ENTRIES IN THIS SERIES ARE ED 003 045 AND ED 003 046. (HS)
