        n

            __
where    X = mean
∑X = sum of the values or measurements
n = number of measurements.

Example:
The measurements are 86, 85, 84, 87, 89.  There are 5 measurements

The sum of the measurements divided by the number of measurements:
Mean = 86 + 85 + 84 + 87 + 89 
                        5
__
X  = 431
         5
