9.1.6 - Experiments

9.1.6 Experiments: laboratory and field; independent and dependent variables.

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

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

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

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