Weighted Mean
Note: When different data values (?) are assigned different weights (?), we can compute a weighted mean.
?̅=
∑(? ∙ ?)

       ∑ ?
Your GPA is computed as a weighted mean. The weights are the units/credits and the values are as
follows:
An A is worth 4 pts, B 3pts, C 2pts, D 1 pt, F 0pt
1) What would your semester GPA be if you earned an A in a 3 unit English class and a 4 unit Chemistry
class, a B in a 5 unit Math class, and a C in a 3 unit History class?
