1.2.5 Random, stratified, volunteer, and opportunity sampling techniques.; Quantitative data.
Use - sampling techniques to connect the rule to the data and decision in the question.
This matters because - sampling techniques determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.
Example: apply - sampling techniques to one small, clearly defined case, show the key step or comparison, and explain the result in words.
Boundary: - Sampling techniques is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
