In colloquial terms, an average is a single number representing a list of numbers, usually the sum of the numbers divided by the number of numbers in the list (arithmetic mean). For example, the average of the numbers 2, 3, 4, 7, and 9 (25 total) is 5. Depending on the situation, the mean can be another statistic, such as median or mode. For example, average personal income is often reported as the median (a number less than 50% of personal income and greater than 50% of personal income). This is because the average is misleadingly high if you include the personal incomes of a small number of millionaires.
