How it works

Fairness gap in this calculator is the absolute gap between two rates in percentage points. With 82 group A, 71 group B the result is Difference between groups: 11 pp.

gap = |group A − group B|. The formula uses group A and group B.

Difference between groups: 11 pp is not an equality audit. Another set of numbers gives Difference between groups: 2 pp, and a further set gives Difference between groups: 22 pp. Empty optional fields do not change the result.

API exposure answers a different question. Documentation does too. Here 82 group A, 71 group B leave Difference between groups: 11 pp.

Type 82 group A, 71 group B and click Calculate. Two more ready sets sit under the form: Difference between groups: 2 pp and Difference between groups: 22 pp.

Other numbers on the same labels move the result. The first example gives Difference between groups: 11 pp.

Formula

gap = |group A − group B|.

How to use
