調和平均計算機

データセットの調和平均を計算します。

はじめに

Harmonic Mean Calculator — Compute the harmonic mean of a dataset. Enter Dataset (comma-separated, non-zero numbers) to get an instant, accurate result.

計算式

Harmonic mean = n / Σ(1/x), n divided by the sum of the reciprocals of each value.

ステップごとの説明

  1. Enter the Dataset (comma-separated, non-zero numbers).
  2. Click Calculate to see your result instantly.

実例

Example: With Dataset (comma-separated, non-zero numbers) = 1, 2, 4, the Harmonic Mean Calculator gives Harmonic Mean: 1.7143.

よくある質問

When is harmonic mean the right choice?
It's best for averaging rates, such as speeds over equal distances or price-to-earnings ratios, where the arithmetic mean would overstate the true average.
What happens if a value is zero?
The harmonic mean is undefined if any value is zero, since it requires dividing by that value.
What inputs does the Harmonic Mean Calculator need?
You'll need to provide: Dataset (comma-separated, non-zero 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 Harmonic Mean Calculator?
The Harmonic Mean Calculator applies the formula exactly as calculated — Harmonic mean = n / Σ(1/x), n divided by the sum of the reciprocals of each value. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Harmonic Mean Calculator free to use?
Yes, the Harmonic Mean Calculator is completely free, requires no signup, and runs instantly in your browser.

調和平均計算機について

The Harmonic Mean Calculator uses a real, verifiable formula — Harmonic mean = n / Σ(1/x), n divided by the sum of the reciprocals of each value. — so results are accurate every time, not an approximation.
