Short Answer

Why can beta = 1/25 balance collections of very different sizes?

Question: In one to three sentences, explain the total-weight effect of beta = 1/25 on 2,400 clinic notes and 60,000 web notes.

Sample answer: Beta = 1/25 reduces the contribution of the auxiliary web-note set so that the 60,000 web notes carry the same total weight as the 2,400 clinic notes.

Key points:

  • The two collections end up with equal total weight.
  • Beta is applied to the auxiliary web-note data.

Rubric: The answer must state that beta = 1/25 makes the total weight of the two collections equal and identify the web notes as the auxiliary data.
