WHAT'S INSIDE (38 pages)

• 12 topic study guides: probability rules (when to add and when to multiply), two-way tables, conditional probability, relative risk, probability trees, working backwards on trees, expected numbers and checking claims, the normal distribution, inverse normal, finding a missing mean or standard deviation, judging whether a normal model fits, and comparing distributions

• 24 practice questions graded Achieved to Excellence, with step-by-step worked answers

• A full mock exam in the real three-question format, with a marking guide that shows what earns Achieved, Merit and Excellence

• How 91267 is marked, what NZQA's 2025 report says, a topic checklist, a two-week plan and a night-before summary

WHY IT WORKS

• Built around NZQA's 2026 specification and 2025 report: drawing trees from words, relative risk above and below 1, and comparing shape, centre and spread

• Shows how to evaluate a claim, which is where Excellence is won
