Use this calculation to reproduce a defined quantitative method when the observations, units, sampling process, and assumptions match the method shown here.

Values

Required list. Positive finite values, such as rates or ratios.

The cited overview of Harmonic mean supplies background for the terminology and domain context used by this tool.^[1]

Calculate the harmonic mean of a nonempty list of positive numbers. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Harmonic mean

Returned number.

• A numerical result does not by itself establish data quality, causation, representativeness, independence, distributional fit, or practical significance.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Inspect the underlying data, visualize its distribution, report uncertainty and sample size, and compare the result with a robust or domain-specific method where appropriate.
