Statistics Calculator

Summary

Enter a list of numbers and get count, sum, mean, median, mode, range, min, max, variance, standard deviation, quartiles, IQR, and a sorted list — all in one click.

How it works

1. Type or paste your numbers into the input box — separate them with commas, spaces, or newlines.
2. Choose "Sample" or "Population" to control whether variance and standard deviation use n-1 or n as the denominator.
3. Click "Calculate" to compute all statistics at once.
4. Click the copy button next to any result to copy that value to your clipboard.
5. Click "Reset" to clear the input and results and start over.
