Correlation vs Causation
Two things happening together doesn't mean one caused the other — recognise the difference between correlation and causation before drawing conclusions
Lesson
Set out your lesson
“Correlation means two quantities vary together. Causation means a change helps produce another change. A shared cause can make two quantities rise together. A pattern alone cannot choose between these explanations. Safety: Paper analysis only; no personal records, dietary changes or water activity. Stop: End after one additional-data proposal. Do not survey children or run food, health or swimming experiments.”
Bring to the table
- Paper and pencil
- Two colouring pencils
Extra for the adult
Worked example. Answer: both counts increase from day A to day D. This is an association in the invented table. Warmer weather is a possible shared cause. The table does not establish that buying ice cream causes swimming, because weather changes too and no causal comparison was made.
Optional challenge. Invent a different pair that might rise together because of a shared cause, clearly labelled invented.
What to notice. Keep the table, arrows and two conclusion sentences. Note supplied-explanation or adult reading support.

Check understanding
- developmental changes in children's recognition of evidence relevance to causal explanations
- causal learning research
“If your child noticed that children who eat breakfast tend to do better at school, would they understand that breakfast might not be the cause — there could be another reason both things are true?”
