To find the mean of a set of data, add up all the numbers in the set and then divide the sum by the total number of values in the set.
So, adding up the numbers: -2 + (-4) + 5 + 6 = 5
There are a total of 4 values in the set.
Dividing the sum by the total number of values: 5 / 4 = 1.25
Therefore, the mean of the data set is 1.25.
Find the mean of the data set.
