Hello There!

Mean: Average of numbers in a set of data.

STEP 1: Add up the numbers. In this case, we would add

4 + 8 + 18 = 30

STEP 2: Divide the sum of the number by the number of digits we have. We would divide 30 "sum of numbers" by 3 "number of digits" and we would end up with an answer of 10.

30  ÷  3  ≈  10
