Hello There!
Mean: Average of numbers in a set of data.
STEP 1: Add up all the numbers in the set of data. In this case, we would add
23 + 23 + 24 + 24 + 25 + 26 + 28 + 28 + 28 = 229
STEP 2: Divide the sum by the number of digits you added. We would divide
229 "sum of the numbers" by 9 "number of digits" and will get a quotient of
25.4444
-The mean for the set of data is 25.4444-
