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 o points. the results for the test are listed in the table below. score number of students 11 18 52 13 6 using the numerical equivalents (weighted values), what is the average grade for this test? rounded to the nearest hundredth, the average grade is

 Average grade for this test is 2.15 .

Step-by-step explanation:

Formula

As given

Students get two grades for a test in an introductory psychology course: a letter grade, and a numerical equivalent (weighted value).

   Grade    Points    Student Score

      A          4             11            44

      B           3            18           54

      C           2            52          104

      D           1              13           13

      F           0             6            0

Sum of total score = 44 + 54 + 104 + 13 + 0

                               = 215

Total number of the students  = 11 + 18 + 52 + 13 + 6

                                                  = 100

Putting all the values in the mean formula

Mean = 2.15

Therefore  average grade for this test is 2.15 .
