Statistics questions reward careful interpretation as much as calculation. Build confidence by understanding the context, choosing an appropriate representation or probability method, and explaining conclusions precisely. The main course combines teaching, practice and complete worked solutions.
Sampling & data
Understand populations and samples, organise information and interpret statistical diagrams and summaries in context.
Probability
Build probability reasoning carefully, including the structure of events and the information supplied by tables, diagrams and models.
Interpretation
Use calculations to make defensible conclusions, paying attention to context, assumptions and what the data can — and cannot — show.
Exam approach
Read the context before calculating. Define what quantities represent, keep exact values where appropriate and return to the wording of the question when interpreting an answer. A correct number without the required contextual conclusion can leave marks behind.
