Statistics Calculator — free online tool
You have a list of numbers and you need the average. Maybe a teacher wants the mean and median of some test scores, or you just want to make sense of a few measurements. Doing it by hand is slow and easy to get wrong. We added a free tool that does it for you — Statistics Calculator — right in your browser.
What it does
Paste in your numbers and it gives you the mean (the average), the median (the middle value), the mode (the one that shows up most), the range (the gap between the smallest and largest), and the standard deviation (how spread out the numbers are). The answers appear right away.
Nothing leaves your device
Everything happens inside your browser. Your numbers are never uploaded to a server and nothing is saved. When you close the page, it's gone.
How to use it
- Open Statistics Calculator.
- Type or paste your numbers in.
- Read the results — mean, median, mode, range and standard deviation, all at once.
It's free with no limit. There are more small tools on the Apps page.
