9.1.8 - Correlational research

9.1.8 Correlation research: type of correlation: positive, negative and use of correlations including issues with cause and effect and other variables.

Use - correlational research to connect the rule to the data and decision in the question.

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

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

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