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

Minimum

Required number.

Maximum

Required number.

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

Calculate the range divided by the sum of maximum and minimum values. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Coefficient of range

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.

• Range Calculator

  Calculate the minimum, maximum, and range of a finite numeric list.

• Coefficient of Determination Calculator

  Calculate R² from paired observed and predicted values.

• Gini Coefficient Calculator

  Calculate the 0–1 Gini inequality coefficient for nonnegative observations using the sorted-sum formula. An all-zero sample is undefined, not perfectly equal.
