Statistics Calculator

Paste a list of numbers to see a descriptive summary. Sample (n − 1) and population (n) spread are both listed so you can pick the one you meant.

How it works

The mean is the arithmetic average. The median is the middle value after sorting (or the average of the two middle values). Mode is the most frequent value — or “no unique mode” if every value appears once. Range is max − min.

Sample variance divides by n − 1; population variance divides by n. This page does not run a hypothesis test or fit a regression.

Formula

Mean = Σx / n
Median = middle of the sorted list
Range = max − min
s² = Σ(x − x̄)² / (n − 1),  σ² = Σ(x − μ)² / n

Worked examples

  • 1, 2, 3

    1, 2, 3 → mean 2, median 2, sample SD 1, no unique mode

  • A repeated value

    1, 2, 2, 3 → mode 2

Useful notes

  • The dedicated standard-deviation page is better when you only want one method.
  • The average calculator is mean-only.

FAQ

What is the difference between sample and population SD?

Sample divides by n − 1. Population divides by n. Both are shown here so you can choose.

What if every number is different?

There is no unique mode. The page says so instead of listing every value.

Are the numbers uploaded?

No. The list is summarised in your browser.
