find the mean of the following data set:

Question

20, 30, 32, 16, 31, 32, 13, 20, 28, 32, 15, 18, 20, 21, 32

Answer 1

The mean can be found by adding up all the numbers and dividing by the total number of numbers:

(20 + 30 + 32 + 16 + 31 + 32 + 13 + 20 + 28 + 32 + 15 + 18 + 20 + 21 + 32) / 15 =

408 / 15 =

27.2

Therefore, the mean of this data set is 27.2.
