Statistical investigations and inference
Use the Skillr scratchpad or a notebook to evaluate whether the sample and source justify the conclusion, and identify any limitations.
SkillrHub quiz practice is built for curriculum-aligned revision with answer feedback and a clear review path.
60-second Quick Read
- Population inference depends on the target population, sampling method, coverage and uncertainty.
- Source quality must be judged against the investigation question; no single source is automatically sufficient.
- Common trap: Statistical conclusions should report sampling limitations and relevant cultural or historical context.
