Mean = the mathematical average = the sum of all the numbers in the set divided by how many numbers there are in the set.

The sum of the all the numbers {-5,-1,8,6,-2,9,-7,2} = 10

There are 8 numbers in the set.

Mean = 10 / 8 = 1.25

The mean (average) is found by adding all the numbers and dividing by the number added. In this case, that amounts to +10/8 or +1.25
