Statistics Calculator
Type a list of numbers. You get mean, median, mode, quartiles and standard deviation — plus combinations, permutations and normal-distribution probabilities.
Example — Mean of 2, 4, 4, 6Mean = 4, median = 4
How we got it — the example, step by step
- Add everything: 2 + 4 + 4 + 6 = 16.
- Divide by the count, 4: 16 ÷ 4 = 4.
- Median: the middle two values are 4 and 4, so the median is 4.
Questions people also ask
Population or sample standard deviation?
Both are printed, labelled. Population divides by n; sample divides by n − 1. Use sample when your numbers are a sample of something bigger.
Can it do combinations?
Yes — C(n, r) and P(n, r) with the formula written out in numbers, and normal probabilities from a mean, a standard deviation and a value.
