Hello There!
Mean: Average of numbers in a set of data.
STEP 1: Add the numbers up. In this case, we would add
12 + 17 + 16 + 10 + 20 + 13 + 14 + 14 + 12 + 12 + 19 + 18 = 177
STEP 2: Divide the sum of the number by the number of digits you added.
We would divide 177 "sum of numbers" by 12 "number of digits" and would
get a quotient of 14.75
The mean for this set of data is 14.75
