Statistics Calculator

Mean, median, mode, standard deviation and more

About Statistics Calculator

Statistics Calculator computes count, sum, mean, median, mode, standard deviation, variance, range, minimum, and maximum from a comma-separated list of numbers, entirely in your browser.

How to use Statistics Calculator

  1. 1Enter your numbers into the text box, separated by commas (e.g., "1, 2, 3, 4, 5").
  2. 2Click "Calculate" to process your dataset.
  3. 3Review all ten statistics displayed at once: count, sum, mean, median, mode, standard deviation, variance, range, min, and max.
  4. 4Edit your data and recalculate any time to analyze a different dataset.

Frequently Asked Questions

What does it compute?

Count, sum, mean, median, mode, standard deviation, variance, range, minimum, and maximum — quartiles aren't currently included.

Does it use population or sample variance?

Population variance and standard deviation (divides by the count of values, N) — not the sample formula (N−1).

How should I separate my numbers?

Use commas between values (e.g., "1, 2, 3"). Space-separated numbers without commas won't be parsed correctly.

Is there a size limit?

No hard limit is enforced — very large datasets are limited only by your browser's performance.

Tips & Tricks

  • ✓Always separate values with commas, even if you're pasting a column of numbers from a spreadsheet.
  • ✓Check the "Count" result to confirm all your values were parsed correctly, especially after pasting data.
  • ✓This calculator uses population variance (÷N) — if you need sample variance (÷N−1) for inferential statistics, adjust manually.
  • ✓Non-numeric entries are silently skipped, so double-check your input if the count looks lower than expected.
