Readings, range and significant figures (Unit 6)
Judge how many readings and how much range the claim needs, and round a value that is too precise.
Wrong units and a point that does not fit (Unit 6)
Amend a unit that contradicts the instrument, and check an inconsistent reading before you drop it.
Improvements that reduce a named error (Unit 6)
Suggest apparatus or a step that fixes the weakness you can see, without changing the question.
