How it works
For positive values x₁, x₂, ..., xₙ, the harmonic mean is:
n / (1/x₁ + 1/x₂ + ... + 1/xₙ)
Examples
- 2, 3, 6 → harmonic mean = 3
- Useful for averaging rates such as speed or price-per-unit style data
FAQ
- What is the harmonic mean?
The harmonic mean is the number of values divided by the sum of their reciprocals.
- When is the harmonic mean useful?
It is useful for averaging rates, ratios, speeds, and quantities measured per unit when the denominator matters.
- Why can’t the input contain 0?
Because the formula uses reciprocals, and division by zero is undefined.
