More about this calculation
The average, or arithmetic mean, is found by adding a group of numbers and dividing by how many there are. This calculator returns the average, sum and count.
Averages summarise a set of values with a single number and are widely used in school grades, statistics and finance. Because every value counts equally, the average can be pulled up or down by very large or very small numbers, so it is often reported together with the median.
