How to calculate an average

The mean is the sum of all values divided by how many there are: average = sum ÷ count. For the numbers 12, 18, 24, 31 and 9 the sum is 94 and the count is 5, so the average is 18.8.

Mean versus median

The median is the middle value once the numbers are sorted. It is useful when a few extreme values would otherwise drag the mean up or down — for example in salary or house-price data.

Accepted input

Commas: 12, 18, 24
Spaces or new lines: one value per line pasted from a spreadsheet
Decimals and negative numbers: -4.5, 7.25

Frequently asked questions

What separators can I use?

Commas, semicolons, spaces and new lines all work, so you can paste a column straight out of a spreadsheet.

What happens to text that is not a number?

It is skipped and the tool tells you how many entries were ignored, so the average is never distorted.

Does it handle decimals and negatives?

Yes. Both decimal values and negative numbers are included in every statistic.

What is the range?

The range is the maximum minus the minimum, showing how widely spread your numbers are.
