Author note — to cover

Describe correlation from a scatter graph: positive, negative or none, strong or weak, and translate the description into context, such as taller people tending to be heavier. Interpretation only, plotting sits on Presenting data. No correlation coefficients or ranked correlation; numerical measures are A level and GCSE Statistics. Both tiers. (S6)

• Fluency — direct questions on describing correlation, limited to this lesson's stated scope (4 questions).
• Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
• Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
