Simple or Arithmetic average of a range of values or quantities, computed by dividing the total of all values by the number of values.


For Example : the mean of 3, 5, 7, 6, 4 is ( 25 / 5 ) = 5.


It is the most common and best general purpose measure of the mid – point of a set of values, but is prone to distortion by the presence of extreme values and may require use of measure of distortion such as mean deviation or standard deviation. This mean is also known as Arithmetic Mean.
