-Sum the squares of the values in data set, and then divide by the number of values in data set
- From that, subtract the square of the mean (add all values and divide by number of values in the data set)
Our variance is
<span>

Since variance has to be 14, we set

and solve for m

quadratic formula

-4 doesnt' work as it is not a positive integer
m = 11
