PREDICTING GRADES FROM BELOW CHANCE TEST SCORES.
GLADNEY, MARILYN B.; HILLS, JOHN R.
THIS STUDY IS AN ATTEMPT TO DETERMINE WHETHER THE USE OF BELOW-CHANCE SCORES CAN BE EXPECTED TO GIVE DIFFERENT RESULTS IN PREDICTION OF GRADES THAN THE USE OF ABOVE-CHANCE SCORES, THAT IS, WHETHER IT IS SOUND TO USE BELOW-CHANCE SCORES IN AN ACADEMIC-PREDICTION REGRESSION EQUATION. DATA WERE OBTAINED FROM THE THREE PUBLIC, PREDOMINANTLY NEGRO COLLEGES IN GEORGIA. THE STUDENTS WERE THOSE WHO ENTERED IN THE FALL QUARTER OF 1964 AND COMPLETED THE ACADEMIC YEAR. THE STUDENTS WERE DIVIDED INTO SEVERAL GROUPINGS ACCORDING TO THEIR SCHOLASTIC APTITUDE TEST (SAT) SCORES. CORRELATIONS WERE COMPUTED BETWEEN SCORES AND 1ST-YEAR GRADE AVERAGE. THESE DATA SEEM TO INDICATE THAT BELOW-CHANCE TEST SCORES ARE AS PREDICTIVE OF PRACTICAL CRITERION (COLLEGE GRADES) AS ARE ABOVE-CHANCE TEST SCORES. THE STUDY ALSO EXAMINED THE USEFULNESS OF RANGE-RESTRICTION-ADJUSTMENT PROCEDURES IN SUCH APPLICATIONS. REGRESSION TESTS FOR SEVERAL SAMPLES WITH BELOW-CHANCE SCORES WERE NOT DIFFERENT FROM THE REGRESSION LINES IN THE ABOVE-CHANCE SAMPLES. THE RANGE-RESTRICTION-ADJUSTMENT PROCEDURES GAVE ERRATIC RESULTS SUGGESTING THAT THEY SHOULD NOT BE RELIED ON WHEN VARIABILITY IS AS SEVERELY RESTRICTED AS IS THE CASE IN STUDYING BELOW-CHANCE SCORES.
