Now that we know the definitions, we can solve this.
21, 24, 26, 28, 32, 34, 36, 52
The largest number is 52; the smallest number is 21.
52 - 21 = 31
31 is the range.
-------------------------------------------------------------------------------------------------------------
21 + 24 + 26 + 28 + 32 + 34 + 36 + 52 = 253
There are 8 numbers in this data set.
253 ÷ 8 = 31.625
31.625 is the mean.
