How it works
Summarize a data set with central tendency and spread. Population divides by n; sample divides by n−1. Variance is std dev squared.
x̄ · GM · σ/s · σ²/s² · Q1 Q3 IQR
When to use
Use this tool when you need to: try 10, 2, 38, 23, 38, 23, 21, 23 — mean 22.25, GM ≈17.12, σ ≈11.51, s ≈12.30. Non-positive data leaves GM undefined.
