How to use this tool

  1. Enter nonnegative values.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Sort ascending and use G=2Σ(i×xi)/(nΣxi)−(n+1)/n, with ranks i starting at one.

A WORKED EXAMPLE

Using nonnegative values = 0, 0, 10, 10, the result is 0.5. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Uncorrected population convention; finite sample maximum is (n−1)/n. Negative values and an all-zero total are unsupported. A descriptive or probability calculation under the stated assumptions. Check the sample design and model before interpreting results.
