Average Calculator

How to work out an average

1. Type or paste your numbers, separated by spaces, commas, or new lines.
2. The results appear as you type.
3. Read the mean, median, mode, and more.
4. Copy the link to share the same set of numbers.

Mean, median, and mode

These three "averages" answer different questions. The mean is the sum of the numbers divided by how many there are, the everyday average. The median is the middle number once they are put in order, which is not thrown off by one very large or small value. The mode is the number that appears most often, and a list can have more than one mode or none at all.

What else it shows

Along with the mean median mode set, the tool gives the count, the sum, the range (the largest minus the smallest), and the smallest and largest values. So one paste answers most questions about a set of numbers.

A quick example

For the numbers 4, 8, 8, and 20: the sum is 40, so the mean is 10. In order they are 4, 8, 8, 20, so the median is 8, halfway between the two middle values. The mode is 8, since it appears twice. The range is 20 minus 4, which is 16.

FAQ

How do I calculate the average of numbers?

Paste the numbers and read the mean, which is the sum divided by the count. To calculate average, or find the average of a set by hand, add the numbers up and divide by how many there are.

What is the difference between mean and median?

The mean is the sum divided by the count. The median is the middle value in order. The median ignores extreme values, so it can be a fairer "typical" number for skewed data.

Can it show the mode?

Yes. This mean calculator also shows the mode, the value that appears most often. If every number is unique, it reports no mode.

How should I separate the numbers?

Use spaces, commas, or new lines. The tool reads any run of digits, so mixing separators is fine.

Are my numbers private?

Yes. Everything runs in your browser and nothing is saved.
