Count how many numbers are in a given set of numbers. For example, in the set "28, 34, 22, 36, 44," there are five numbers in the set.
Add up the sum of all the numbers in the set. In this case, 28 + 34 + 22 + 36 + 44 = 164.
Divide the sum of the numbers in the set by the amount of numbers in the set. For this calculation, "164 / 5 = 32.8" is the equation. This is the mean of the given numbers.
Round the number to the nearest whole number if the result involves a repeating decimal. For this set, the mean when rounded is 33, as it's the closest whole number. Be sure to state that this is an approximation if you do this.
