Mean: Average of the numbers in a set of data
To find the mean of the test scores, we need to add up the test scores and divide the sum by the number of tests there are. First, let’s add the test scores.
72 + 86 + 91 + 25 + 37 + 52 = 363
Now, let’s divided 363 by the number of tests there are. In this case, there are six tests so we would divided 363 by 6.
363 ÷ 6 = 60.5
Therefore, the average of these test scores was 60.5.
