GPA stands for “Grade Point
Average.” Grade point average is calculated this way: 4 points for an “A”
grade, 3 points for a “B” grade, 2 points for a “C” grade, 1 point for a “D”
grade, and zero points for an “F” grade. The highest possible theoretical GPA
is a 4.0; every single person in the survey would need to give an "A" grade for
that to happen.
By way of illustration: If, in a
survey of 500 adults, responses divided as follows:
210 respondents gave an “A” grade
(4),
160 gave a “B” grade (3),
70 gave a “C” grade (2),
10 gave a “D” grade (1),
40 gave an “F” grade (0), and
10 said they were not sure,
then the formula, to calculate the
grade point average would be
((210 * 4) + (160 * 3)
+ (70 * 2) + (10 * 1) + (40 * 0))
 = 1470 / 490 =
GPA of 3.00 = GPA of B.
(210
+ 160 + 70 + 10 + 40)
