Hello!
In order to find the mean of a set of numbers, you simply need to sum all the numbers, and then divide that sum by the size of the set (the number of values in the set).

Let's start with the sum:
13%2B15%2B18%2B18%2B18%2B19%2B22%2B26%2B28%2B33+=+210
Now, how many numbers are there in the set? If you count them, you'll see that you have 10 numbers. Therefore, the mean of this set is:
210%2F10+=+21
Therefore, the mean is 21.

I hope this helps!

The mean or average of a set of numbers is found by adding of the numbers then dividing the total by the number of numbrs you added.
In your problem, you will add up the given set of numbers:
13+15+18+18+18+19+22+26+28+33 = 210
Now you will divide this total (210) by how many numbers there are, and that's 10. So:
210%2F10+=+21
The mean is 21
