How it works
For positive values x₁, x₂, ..., xₙ, the geometric mean is:
(x₁ × x₂ × ... × xₙ)^(1/n)
Examples
- 2, 8 → geometric mean = 4
- 2, 8, 4 → geometric mean = 4
- 1.5, 3, 6 → useful for multiplicative scaling comparisons
FAQ
- What is the geometric mean?
The geometric mean of positive numbers is the nth root of their product, where n is the number of values.
- Why do inputs need to be positive?
This real-number geometric mean tool requires positive values so the nth root of the product is well-defined in the standard way.
- When is geometric mean useful?
It is useful for growth rates, ratios, percentages, finance-like compounding contexts, and multiplicative data.
- Are calculations stored?
No. Everything runs locally in your browser.
