First step when finding the mean is to add all the values together
7 + -9 + 6 + -10 + -13 + -5
To make this easier, first add all the positive numbers 7 + 6 = 13
Then add (basically take away) the minus values one by one
13 - 9 = 4
4 - 10 = -6
-6 - 13 = -19
-19 - 5 = -24
Next step is to divide this total by the number of values there were
In this case, there were 6 values
-24 / 6 = -4
D. -4

Mean of the above set of numbers is D. -4

Mean is the average of the sum of the numbers.

add all the numbers : 7 + (-9) + 6 + (-10) + (-13) + (-5) = -24 
divide the sum by the count of numbers added: -24/6 = -4
