How it works
Calculate comprehensive descriptive statistics for a numeric data set. Inputs are calculated locally in the browser, and valid values are retained in the page URL for bookmarking.
Input query strings and outputs
Use an input name in this page’s URL as ?name=value, and join additional inputs with &. Portable shared links may instead use the compact ?ac= state parameter.

Formula notes
x̄=Σx/n; σ²=Σ(x−μ)²/n; s²=Σ(x−x̄)²/(n−1); geometric mean=(Πx)^(1/n).
Input guidance
Use consistent units for every length or measurement in the same calculation. Results are educational mathematical estimates and should be checked before high-stakes use.
