example - Find the mean for the following list of values:13, 18, 13, 14, 13, 16, 14, 21, 13The mean is the usual average, so:(13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15Note that the mean isn't a value from the original list. This is a common result. You should not assume that your mean will be one of your original numbers.
