2.2.1 - Experiment design and conduct

2.2.1 Designing and conducting experiments, including field and laboratory experiments.

Use - experiment design and conduct to connect the rule to the data and decision in the question.

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

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

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