What is it
KS3 statistics extends KS2 work to scatter graphs and correlation, comparing data sets using averages and range, and understanding when different types of chart are appropriate for different data.
Why it matters
Statistical literacy — knowing whether a claim from data is actually justified — is a genuinely useful life skill in an age of data-driven headlines, on top of being a core GCSE topic in its own right.
Exam tip
When describing correlation on a scatter graph, always describe both the type (positive, negative, or none) and the strength (strong or weak) — a one-word answer like 'positive' alone rarely earns full marks.
