2.2.3 - Experimental and null hypotheses

2.2.3 Experimental and null hypotheses.

Use - experimental and null hypotheses to connect the rule to the data and decision in the question.

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

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

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