FACTOR ANALYSES OF ACHIEVEMENT MEASURES FROM THE EDUCATIONAL OPPORTUNITIES SURVEY.
MAYESKE, GEORGE W.; WEINFELD, FREDERIC D.
FACTOR ANALYSES WERE APPLIED TO TABLES OF INTERCORRELATIONS ORIGINALLY COMPUTED FOR 11 GROUPS OF NINTH GRADERS (NORTHERN AND SOUTHERN NEGRO AND WHITE, PUERTO RICAN, MEXICAN, INDIAN, AND ORIENTAL-AMERICAN) ON FIVE ACHIEVEMENT MEASURES USED BY COLEMAN AND OTHERS IN THE EDUCATIONAL OPPORTUNITIES SURVEY. THE PURPOSE OF THE FACTOR ANALYSIS WAS TO DETERMINE WHETHER THE FIVE TESTS--NONVERBAL ABILITY, VERBAL ABILITY, READING COMPREHENSION, MATHEMATICS ACHIEVEMENT, AND GENERAL INFORMATION--HAD ENOUGH IN COMMON IN WHAT THEY WERE MEASURING TO BE COMBINED INTO ONE SCORE--AN "INDEX OF ACHIEVEMENT" SCORE. IN ORDER TO MEET THE REQUIREMENTS FOR COMBINING THE FIVE SCORES INTO ONE, TWO REQUIREMENTS OF THE FACTOR ANALYSIS WERE ESSENTIAL--(1) THAT THE FIVE MEASURES WERE MEASURING TO A HIGH DEGREE ONLY ONE THING IN COMMON (WHICH WOULD BE SHOWN IF THE FACTOR ANALYSIS FOUND HIGH VALUES FOR THE FIRST FACTOR EXTRACTED), AND (2) THAT WHEN "FIRST FACTORS" WERE COMPUTED FOR EACH OF 10 SUBGROUPS, THESE FIRST FACTORS WOULD NOT DEVIATE FROM THE FIRST FACTOR EXTRACTED FROM THE TOTAL GROUP. THE RESULTS OF 11 FACTOR ANALYSES INDICATED THAT BOTH OF THESE REQUIREMENTS WERE MET, AND THEREFORE THE NUMBERS OF THE FIRST FACTOR OF THE TOTAL GROUP COULD BE EMPLOYED AS "WEIGHTS" TO MULTIPLY EACH INDIVIDUAL'S SCORE ON EACH OF THE FIVE MEASURES FROM THE COLEMAN STUDY SO THAT THEY MIGHT BE COMBINED (ADDED) TO FORM ONE INDEX OF ACHIEVEMENT SCORE. THE WEIGHTS FOR THE FIVE TESTS ARE--NON-VERBAL (.76), VERBAL (.92), READING COMPREHENSION (.87), MATHEMATICAL ACHIEVEMENT (.85), AND GENERAL INFORMATION (.91). (WT)
