Students get two grades for a test in an introductory psychology course: a letter grade, and a numerical equivalent (weighted value). So an A is worth 4 points, a B is worth 3 points, a C is worth 2 points, a D is worth 1 point, and an F is worth 0 points.

The results for the test are listed below
11 students made F.
18 students made D.
52 students made C.
13 students made B.
6 students made A.
Using the numerical equivalents (weighted values), what is the average grade for this test?

1.85

1.85

11 * 0 = 0

18 * 1 = 18
52 * 2 = 104
13 * 3 = 39
6 * 4 = 24

Add these sums together and divide by 100 to get the average.

To find the average grade for the test using the numerical equivalents (weighted values), we need to calculate the sum of all the weighted values and then divide it by the total number of students.

Let's calculate the sum of the weighted values:
F: 11 students * 0 points = 0
D: 18 students * 1 point = 18
C: 52 students * 2 points = 104
B: 13 students * 3 points = 39
A: 6 students * 4 points = 24

Now, let's find the total number of students:
Total students = 11 (F) + 18 (D) + 52 (C) + 13 (B) + 6 (A) = 100

Next, we will calculate the average grade:
Average grade = Sum of weighted values / Total number of students
Average grade = (0 + 18 + 104 + 39 + 24) / 100
Average grade = 185 / 100
Average grade = 1.85

So, the average grade for this test using the numerical equivalents is 1.85.
