Define Mean for Math. In math, the mean is the average of a set of numbers. To find the mean of a data set, add up all of the numbers in the set, and then divide that total by the number of numbers in the set. In statistics, the mean is one of the three measures of central tendency, which are single numbers that try to pinpoint the central location within a data set.
