Short Answer

Why should the test set be made large enough?

Question: Answer in one to three sentences using only the underlying principle.

Sample answer: A larger test set makes the evaluation less noisy, so the measured score is a more trustworthy estimate of how the model will do on future data.

Key points:

  • Less evaluation noise
  • More trustworthy estimate
  • Future data performance

Rubric: Full credit requires mention of both reduced uncertainty in evaluation and a reliable estimate of future performance; answers that only say the set should be big are incomplete.
