Understanding your result
These are descriptive results for the observations you entered, not proof of causation, significance or a particular population distribution.
Common mistakes
- Using nonpositive observations or applying this mean to a quantity for which its interpretation is inappropriate.
Check your calculation
- Try a small hand-checkable list; confirm the stated quartile/rank/denominator convention before comparing with another application.

Common uses
- Find the geometric mean of positive numbers using their logarithms.
How it works
exp(mean(log(x))) Lists accept commas, semicolons, spaces or line breaks as separators; use a dot for decimals. At most 10,000 observations are supported. Calculations use floating-point arithmetic; displayed numeric results have up to 12 significant digits.
Worked example
Enter Numbers: 1, 4, 16. The result is Geometric mean: 4.
