How to use

  1. Paste or type your numbers into the input.
  2. Separators can be commas, spaces, tabs, semicolons, or new lines.
  3. Stats update as you type.

Examples

10, 20, 30, 40, 50
Mean 30, median 30, sum 150, std dev ≈ 14.14
Mixed separators
"1 2\n3,4;5" → same as "1,2,3,4,5" — mean 3, range 4.

Before you trust the result

Check the inputs that matter most: dates, rates, units, costs, and any optional fields you skipped. A calculator can only work with the numbers entered here, so use the result as a decision check rather than a final answer when money, health, tax, legal, or safety consequences are involved.

If the result feels surprising, change one input at a time and watch which number moves. That usually shows the real lever behind the decision.

Frequently asked questions

› Which standard deviation does this use?

Population standard deviation (divide by N). For sample std dev, multiply by √(N/(N−1)).

› Are non-numeric values ignored?

Yes. Anything that does not parse as a number is skipped silently.
