Case 54 — Two laboratories, two percentages: are they measuring the same thing? · comparison exercise

Limit of the answer in “Two laboratories, two percentages: are they measuring the same thing?”: “Before comparing laboratories, ask whether sample handling, method conditions…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: comparison. Make the basis of a comparison explicit before interpreting it.
