2 How this connects to the other Level 3 Statistics standards
The confidence-interval reasoning here is the same statistical inference machinery 91585 and 91586 build on — only the source of the data (a media report vs your own analysis) changes.Shared ideas across the Level 3 Statistics externals
- A confidence interval's three-case judgement (entirely above, entirely below, or straddling the value) is the identical inference logic used wherever confidence intervals appear across the subject.
- The observational-vs-experimental distinction, and what each design can and cannot support, underlies any standard asking you to interpret a study's conclusions.
- The margin-of-error rule (MoE ≈ 1/√n) and its 30-70% caveat is reusable wherever a sample proportion needs a quick, honest confidence interval.
