To find the mean, the numbers are added and divided by the [[quantity]] of numbers in the group.  For example: to find the mean of 3, 4, 6, and 7, we add them together: <math>3 + 4 + 6 + 7 = 20</math>.  Then we divide them by the quantity of numbers in the group, which is 4.  <math>20/4 = 5</math>.

Most [[spreadsheet]] programs and [[computer language]]s consider ''average'' to be the mean, but there are three common types of [[average]]. Often the [[median]] is far from the [[mean]], when values are skewed in one direction.
