3.2.3 Issues surrounding the use of correlations in psychology; issues with cause and effect, other variables.

Use - correlation issues to connect the rule to the data and decision in the question.

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

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

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