Show answer
Answer
- A Improve or balance the data for this group
- D Identify and check proxy features
- E Measure results per group again after the change

Effective measures are better or balanced data, checking correlated features and measuring again per group. Merely deleting the protected attribute is often not enough, because proxies carry the bias on.
