2.2.6 - Operationalisation and variables

2.2.6 Operationalisation of variables, extraneous variables and confounding variables.

Use - operationalisation and variables to connect the rule to the data and decision in the question.

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

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

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