The GCSE Statistics exam covers probability, data handling, and statistical analysis. Key topics include correlation, sampling methods, risk calculation, population trends, index numbers, and the Product Moment Correlation Coefficient (PMCC). Other areas include weighted means, standardised scores, and hypothesis testing. Questions assess interpretation of histograms, population pyramids, and data trends. Real-world applications involve quality control, demographic studies, reaction time experiments, and comparative performance analysis. Statistical methods like skewness, stem-and-leaf diagrams, and sampling decisions are emphasized. Analytical reasoning and data comparison play a central role throughout.
