A comprehensive revision workbook covering Section A of the AQA GCSE Statistics specification (8382). Designed for Foundation and Higher tier students, this workbook builds the planning and hypothesis skills that underpin the entire course — and that AQA regularly tests in the opening questions of both papers.

Topics covered:
Writing and evaluating hypotheses — what makes a valid hypothesis, common errors, exam shortcut
Constraints in statistical investigations: time, cost, ethical issues, confidentiality and convenience
Proactive mitigation strategies: non-response, identifying the population, unexpected outcomes, pilot studies
Reliability and validity of data collection methods
Representative samples and sources of bias
Pilot studies: purpose, benefits, and how to use findings to improve an investigation

Workbook features:
Full AQA spec coverage for Section A (A1–A3)
Worked examples using authentic contexts including 2024 AQA exam questions
Common mistake boxes drawn from AQA examiner reports
Questions labelled by assessment objective (AO1, AO2 and AO3) — including evaluate and justify questions that match the AO2/AO3 weighting of the real exam
Full mark scheme with context-specific guidance

Suitable for classroom use, independent revision, and tutoring. Compatible with the 2019–onwards specification.
