What is an Average (Mean)?

The average, or mean, is one of the most commonly used statistical measures. It is calculated by adding all the values in a dataset and dividing the total by the number of values. The formula is:

Average = (Sum of all values) ÷ (Number of values)

For example, if your numbers are 10, 20, and 30, the sum is 60 and there are 3 values. So the average is 60 ÷ 3 = 20.
