grade D - 2 students - 4,9 percent

grade C - 6 students - 14,7 percent

grade B - 12 students - 29,2 percent

**bobpursley**, Wednesday, February 17, 2010 at 10:39amYou have to assign a value to A,B,C,D. Since I dont know the grading scheme you have, I will make up one:

A=4.0

B=3.0

C=2.0

D=1.0

F=0

avg grade=sum of values*percent

= 1.0*.049+2.0*.147+3.0*.292+4.0*.512

I get 3.27

**Damon**, Wednesday, February 17, 2010 at 10:41amAssign numbers to grades like 1 = D and 2 = C and 3 = B and 4 = A

The sum of all the grades divided by the number of students.

[ 2*1 + 6*2 + 12*3 + 21*5 ] / [2+6+12+21]
