grade D - 2 students - 4,9 percent

grade C - 6 students - 14,7 percent

grade B - 12 students - 29,2 percent

grade A - 21 students - 51,2 percent

What is the average grade?

This is NOT my homework and I am not going to school!I am doing a research about anxiety and I need to calcualte this!

**bobpursley**, Wednesday, February 17, 2010 at 10:39amYou have to assign a value to A,B,C,D. Since I don't 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 - Math - average grade -
**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] - Math - average grade -

**mary**, Wednesday, April 8, 2015 at 8:47pmA student's grade in a course is the average of 4 test grades and a final exam that is worth twice as much as each test. Suppose a student has test grades of 89, 88, 83, and 94. Write an equation to model this situation where xis the student's grade on the final exam and yis the student's average for the course.
