What Is an Average?

An average is a single number that represents the typical value of a group of numbers. It is one of the most common ways to summarize numerical data.

To find an average, you add all the values together and then divide the total by the number of values. This is also commonly called the arithmetic mean.

Our Average Calculator makes this process easier by calculating the result for you and showing the steps used to reach the answer.

How to Calculate an Average

Calculating an average is simple when you follow three basic steps.

1. Add all the numbers

First, add every value in your data set together to find the total sum.

2. Count the values

Next, count how many numbers are included in your data set.

3. Divide the sum by the count

Finally, divide the total sum by the number of values.

Average Calculator Example

Suppose you have the following five numbers:

First, add the numbers:

There are 5 values, so divide the sum by 5:

Therefore, the average of these numbers is 20.
