What Is an Average?
An average, also called the arithmetic mean, is a value that represents the typical or central value of a group of numbers.
To calculate an average, add all the numbers together and divide the total by the number of values in the group.
How to Calculate an Average
The basic process for calculating an average is simple. Follow these three steps:
- Add all the numbers together.
- Count how many numbers you have.
- Divide the total sum by the number of values.
Average Calculation Example
Suppose you have the following five numbers:
10, 20, 30, 40, 50
First, add the numbers:
10 + 20 + 30 + 40 + 50 = 150
There are five numbers, so:
150 ÷ 5 = 30
Therefore, the average is 30.
| Number | Value |
|---|---|
| 1 | 10 |
| 2 | 20 |
| 3 | 30 |
| 4 | 40 |
| 5 | 50 |

Average vs. Mean
In basic mathematics and statistics, the term average commonly refers to the arithmetic mean.
For example, if the numbers are 5, 10, and 15:
(5 + 10 + 15) ÷ 3 = 10
In this case, both the average and arithmetic mean are 10.
However, statistics also includes other measures of central tendency, such as the median and mode. Those are different calculations from the arithmetic mean.
