3.4.4 - Inconsistent readings

Check a reading inconsistent with other readings and record instrument readings using the correct number of significant figures.

Use - inconsistent readings to connect the rule to the data and decision in the question.

This matters because - inconsistent readings determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - inconsistent readings to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Inconsistent readings is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
