Quiz: Group Fairness Metrics: Parity, Equal Opportunity and Equalised Odds

Statistical parity examines whether the probability of positive outcomes remains consistent across protected attributes such as gender or ethnicity.

Equal opportunity focuses on maintaining consistent detection of relevant outcomes rather than overall group representation.

Equalised odds requires that both true positive rates and false positive rates remain consistent across demographic groups.

The implementation of equal opportunity involves measuring recall or sensitivity for each demographic group.

Equalised odds combines equal opportunity with equalised false positive rates to create a fuller measure of group fairness.
