Question: In one to three sentences, explain why reviewing only the misclassified examples in a dev set is more practical than reviewing every example.

Sample answer: With 98.0% accuracy on 1,000 examples, only 20 examples are misclassified compared to 980 correctly classified ones. Reviewing just 20 examples takes much less time and effort than reviewing all 980, making it the more practical choice.

Key points:

  • 20 misclassified examples vs. 980 correctly classified examples
  • Reviewing fewer examples requires less time and effort

Rubric: Full credit requires mentioning the 20 vs. 980 split and that the smaller number of misclassified examples takes less effort to review.
