はじめに

Geometric Mean Calculator — Compute the geometric mean of positive numbers. Enter Dataset (comma-separated, positive numbers) to get an instant, accurate result.

計算式

Geometric mean = (x₁ × x₂ × … × xₙ)^(1/n), computed here via exp(Σln(x)/n). Requires all values to be positive.

実例

Example: With Dataset (comma-separated, positive numbers) = 1, 2, 4, the Geometric Mean Calculator gives Geometric Mean: 2.

よくある質問

When should I use geometric mean instead of arithmetic mean?

Geometric mean is appropriate for rates of change, growth rates, and ratios (like investment returns), where values multiply together rather than add.

Why must all values be positive?

The geometric mean involves taking a logarithm of each value, which is undefined for zero or negative numbers.

What inputs does the Geometric Mean Calculator need?

You'll need to provide: Dataset (comma-separated, positive numbers). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Geometric Mean Calculator?

The Geometric Mean Calculator applies the formula exactly as calculated — Geometric mean = (x₁ × x₂ × … × xₙ)^(1/n), computed here via exp(Σln(x)/n). Requires all values to be positive. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Geometric Mean Calculator free to use?

Yes, the Geometric Mean Calculator is completely free, requires no signup, and runs instantly in your browser.
