Question: If your estimate of avoidable bias comes out negative, what kind of improvement work should you prioritize next?

Sample answer: You should prioritize variance reduction methods rather than additional bias reduction.

Key points:

• Negative avoidable bias suggests bias is not the main remaining problem.
• The next focus should be variance reduction methods.
• Do not keep spending effort on bias reduction as the main step.

Rubric: The answer must explicitly mention variance reduction methods.
