Statistical investigations and scenario data
Use the Skillr scratchpad or a notebook to compare data values, calculate gaps, check ratios and identify bias before choosing an answer.
SkillrHub quiz practice is built for curriculum-aligned revision with answer feedback and a clear review path.
60-second Quick Read
- Statistical investigations begin with a clear question, relevant data source and awareness of possible bias.
- Secondary data can be useful, but comparisons must use consistent units and clear percentage-point differences.
- Common trap: A larger number is not always the better choice; decide what the investigation is trying to optimise.
