In many institutions of higher education, a student’s record is evaluated by a grade point average. For example, 4 points might be given for each semester hour of A, 3 for each hour of B, 2 for each hour of C, 1 for each hour of D, and 0 for each hour of F. These numerical values are multiplied by the num¬

ber of hours of each grade earned, summed, and divided by the total number of hours to arrive at a grade point average. Thus, a grade point average of near 4.00 indicates a fine record and a grade point average below 2.00 indi¬

cates a poor record. In light of the discussion of measurement scales given in the text, discuss the merits of this procedure.
