3.3.1.2b - Portfolio analysis

Explain the aim of portfolio analysis.

Use b - portfolio analysis to connect the rule to the data and decision in the question.

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

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

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