Complete WJEC GCSE Statistics specification revision resources. Tailored syllabus coverage with topic breakdowns, quizzes, and practice questions.
Overview
The WJEC GCSE Statistics specification is designed to equip students with the skills to plan, collect, process, analyse and evaluate statistical data. It goes beyond basic data handling in GCSE Mathematics, offering a dedicated exploration of real-world statistical methods. Throughout the linear two-year course, learners develop a critical understanding of sampling, data presentation techniques, and probability theory, all underpinned by the statistical enquiry cycle.
Key themes include designing effective data collection methods, using appropriate diagrams and measures to summarise data, and drawing valid conclusions through statistical inference. Students learn to interpret and communicate findings clearly, recognising limitations and potential bias. The course nurtures analytical thinking—vital for further study in sciences, social sciences, and business—and provides a strong foundation for A Level Statistics or related subjects.
The specification is structured into two distinct but interconnected areas: 'The Collection and Processing of Data' and 'Probability and Statistical Inference'. This logical split helps students build confidence in data handling before moving on to more advanced probability and hypothesis testing. By the end, they are able to carry out a full statistical investigation, from initial planning to final evaluation.

WJEC is known for straightforward question wording and a specification that stays close to real-world applications, making the content engaging and accessible for a wide range of learners.
Assessment & Exam Structure
Assessment is entirely examination-based, with no coursework. Students sit two written papers, each lasting 1 hour 45 minutes and worth 100 marks. Paper 1 focuses on 'The Collection and Processing of Data', while Paper 2 covers 'Probability and Statistical Inference'. Both papers carry equal weighting—50% of the GCSE each—and the overall qualification is marked out of 200. Grades are awarded on the A* to G scale.
