6.5.9 - Qualitative and quantitative uncertainties

Evaluate uncertainties qualitatively and quantitatively.

Use - qualitative and quantitative uncertainties to connect the rule to the data and decision in the question.

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

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

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