2(5) + 0(4) + 0(3) +0(2) + 5(1) + 4(0) = 10 + 0 + 0 + 0 + 5 + 0 = 15
Divide by # of students, which is 11, and you get the average as 15/11, or 1.3636.

Zero students means no one scored that score, the only scores that were received were "5" (2 students earned) and "1" (5 students earned) and "0" (4 students earned).

The class average would be all the test scores added up and divided by the number of scores.

5+5+1+1+1+1+1+0+0+0+0= 15

15/11=1.37

The class average is 1.37
