To find the mean of a data set, you add up all the values and then divide the sum by the number of values.
-2 + (-4) + 5 + 6 = 5
The sum of the values is 5.
There are 4 values in the data set.
Mean = sum of values / number of values
Mean = 5 / 4
Mean = 1.25
Therefore, the mean of the data set -2, -4, 5, 6 is 1.25.
find the mean of the data set
