How to use the average calculator

  1. Type or paste your numbers, separated by commas, spaces or new lines.
  2. Results update as you type. Anything that isn’t a number is skipped and listed.

Mean, median and mode

Mean
The sum divided by the count. It’s what most people mean by “average”, but a single extreme value can pull it a long way.
Median
The middle value once the numbers are sorted (or the average of the two middle values). It’s less affected by outliers.
Mode
The value or values that appear most often. If nothing repeats, there’s no mode.

Sample or population standard deviation?

Use the population figure when your list contains every value you care about — for example, the scores of everyone in a class. Use the sample figure when your list is a sample drawn from a larger group; it divides by n − 1 to correct for that.

Questions

Can I paste from Excel or Google Sheets?

Yes. Copy a column of cells and paste it in. Each cell arrives on its own line.

Are thousands separators supported?

Commas also separate numbers, so write large numbers without them (1250, not 1,250), or put one number per line.

How many numbers can I enter?

Thousands. Everything runs in your browser.
