What Is an Average?
An average is a single value that summarizes a group of numbers. It helps you understand what’s “typical” in a set—whether you’re checking scores, prices, expenses, or measurements.
In everyday math, the word average usually means the arithmetic mean. It’s one of the most common and easiest statistics to use.
Average Formula
Average = Total Sum ÷ Number of Values
- Total Sum = add all numbers together
- Number of Values = how many numbers you have
Example
For these 5 numbers: 2, 7, 19, 24, 25
- Add them: 2 + 7 + 19 + 24 + 25 = 77
- Divide by the count: 77 ÷ 5 = 15.4
✅ Average = 15.4

How to Calculate an Average
To calculate the average of a group of numbers, do two simple steps:
- Add all the numbers together
- Divide the total by how many numbers you have
Average = (Sum of values) ÷ (Count of values)
Example
Let’s find the average of: 24, 55, 17, 87
- Sum: 24 + 55 + 17 + 87 = 183
- Count: 4 numbers
- Average: 183 ÷ 4 = 45.75
You can do small averages by hand, but when you have many numbers or long decimals, an average calculator is faster and helps avoid mistakes.
If you’re working with an average calculator, an calculate average uses the same idea—it finds the mean based on how many votes each rating received.
