The GCSE Statistics exam evaluates statistical reasoning and data analysis through real-world applications. Key topics include probability, Venn diagrams, and cumulative frequency. It emphasizes data representation using stem-and-leaf diagrams, histograms, frequency polygons, and scatter graphs. Statistical techniques like Spearman’s rank correlation coefficient, standardization, normal distributions, weighted means, and index numbers are covered. Practical scenarios include analyzing birth rates, sampling methods, regression lines, and experimental setups. Real-world contexts such as app effectiveness, flight delays, ice cream preferences, and estimating populations highlight applied problem-solving. Logical interpretation, critical evaluation, and hypothesis testing are central themes throughout.
