AQA GCSE Statistics Past Papers & Mark Schemes

AQA GCSE Statistics (specification code 8382) is a standalone qualification distinct from GCSE Mathematics. It is assessed through two written papers at either Foundation or Higher tier, with 100% written examination — there is no coursework or non-exam assessment component. Students are entered for either Foundation (grades 1–5) or Higher (grades 4–9). Paper 1 and Paper 2 each last 1 hour 30 minutes and are worth 80 marks each. A calculator is permitted in both papers. The content is divided across four topic areas: The Statistical Enquiry Cycle, Data and their collection, Processing, representing, and analysing data, and Probability. The Statistical Enquiry Cycle covers: framing statistical questions, planning data collection, choosing appropriate methods, and interpreting and evaluating results. This underpins the rest of the course and provides context for applied questions in the exam. Data and collection covers: types of data (qualitative, quantitative, discrete, continuous), sampling methods (random, systematic, stratified, cluster, quota, convenience), primary and secondary data, and the design of data collection tools including questionnaires and observation sheets. Processing and representation covers: measures of central tendency (mean, median, mode), measures of spread (range, interquartile range, standard deviation at Higher), cumulative frequency, histograms with unequal class widths, frequency polygons, scatter diagrams, time series, and index numbers. Probability covers: basic probability rules, Venn diagrams, probability trees, conditional probability, and the distinction between theoretical and experimental probability. At Higher tier, questions on probability are more demanding, including combined events and systematic listing strategies. Higher tier papers include harder questions on standard deviation, rank correlation (Spearman's), and more complex data interpretation.
