Question: In one to three sentences, state the source's view of using statistical significance tests to measure interim progress on the dev set.

Sample answer: Most teams do not use statistical significance tests routinely for dev set changes. The author usually does not find them useful for measuring interim progress, though academic research publication is a stated exception.

Key points:

• Most teams do not bother with the tests.
• The author usually does not find them useful for interim progress.
• Academic research papers are the stated exception.

Rubric: The answer should mention both the lack of routine use and the author's view that the tests are usually not useful for interim progress; noting the academic-publication exception strengthens completeness.
