Rolland Poust is a sophomore in the College of Business at Scandia Tech. Last semester he took courses in statistics and accounting, 3 hours each, and earned an A in both.He earned a B in a five-hour history course and a B in a two-hour history of jazz course. In addition, he took a one-hour course dealing with the rules of basketball so he could get his license to officiate high school basketball games. He got an A in this course. What was his GPA for the semester? Assume that he receives 4 points for an A, 3 for a B, and so on. What measure of location did you just calculate?

Grade point average (GPA) is the summation of all the numbered grades obtained divided by the number of credits taken or total obtainable points multiply by the maximum point receivable for a course. This can be calculated as follows:

1. Calculation of Total Obtainable Points

Statistics = A × hrs = 4 × 3 = 12

Accounting = A × hrs = 4 × 3 = 12

History = A × hrs = 4 × 5 = 20

History of jazz = A × hrs = 4 × 2 = 8

Rules of basketball = A × hrs = 4 × 1 = 4

Total obtained points = 12 + 12 + 20 + 8 + 4 = 56

2. Calculation of Total Points Obtained

Statistics = A × hrs = 4 × 3 = 12

Accounting = A × hrs = 4 × 3 = 12

History = B × hrs = 3 × 5 = 15

History of jazz = B × hrs = 3 × 2 = 6

Rules of basketball = A × hrs = 4 × 1 = 4

Total Points Obtained = 12 + 12 + 15 + 6 + 4 = 49

3. Calculation of GPA

GPA = (Total Obtained Points ÷ Total Obtainable Points) × the points that A receives (i.e. maximum GPA)

= (49 ÷ 56) × 4

= 0.875 × 4

= 3.50

Therefore, Rolland Poust's GPA is 3.5 out of 4.

The measure of location that has just been calculated is mean. The mean is obtained by adding all the values and then divide it by the number of values.

Grade point average (GPA) is similar to mean because GPA is the summation of all the numbered grades obtained divided by the number of credits taken.
