How to Calculate the Mean Value
A. Finding the Mean. The mean of a set of values is the sum of the values divided by the number of values. It is also called the average. Example: Find the mean of 19, 13, 15, 25, and 18. 19 + 13 + 15 + 25 + 18 = 90 = 18. 5 5. When the mean is known and you must find a missing value, some simple rules of algebra must be applied. Example:
