Mean Of Data Set

What is the mean of the data set below?

15, 18, 19, 54, 74, 94, 67, 82, 48, 31, 15

To find the mean of a data set, you add up all the values and then divide the sum by the number of values.

So in this case, you would add up:

15 + 18 + 19 + 54 + 74 + 94 + 67 + 82 + 48 + 31 + 15 = 517

And then divide by the number of values, which is 11:

517 / 11 = 47

Therefore, the mean of this data set is 47.
