Hello There!
Mean: Average of numbers in a set of data.
STEP 1: Add the numbers in the set of data. In this case, we would add
60 + 85 + 98 = 243
STEP 2: Divide the sum by the number of digits you added. We would divide 243 "sum of numbers" by 3 "number of digits" and we would get an answer of 81.
The mean for the set of numbers is 81
