How to Calculate Average

The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. For example, suppose we want the average of 24,551787 and 100. Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5to get 56.6. A simple problem such as this one can be done by hand without too much trouble, but, for more complex numbers involving many decimal places, it is more convenient to use this calculator. Note that the mean rating calculator does a similar math - it calculates an average rating given the number of votes with values from 1 to 5.
