The mean is the average. It is the sum of the x-values divided by the total number of observations. for example:

1

3

4

5

7

10

12

15

1+3+5+7+10+12+15=57

There are 8 observations here, n=8

So, 57/8=7.125 This is the mean.

Explanation:

To find the mean in a problem you may read, add all the numbers up. Then divide by how many numbers you have in all. And you get your mean. Easy peasy:)
