IB Maths AI SL 4.1 Sampling & data
Students practise identifying sampling methods (e.g., stratified, convenience), evaluating sample size trade-offs, and extracting totals or values from frequency tables or survey…
How this is tested

- calculate total sample size by summing frequencies across categories in a table
- explain why one air-quality reading is insufficient for a reliable conclusion
