What will I study? – Data and Sampling – Representing data numerically and diagrammatically – Number work which includes algebraic substitution, limits of accuracy, approximating problems in context, percentage changes, simple and compound interest, savings and investment studies. – Money for personal use which includes repayment and cost of credit, tax, National insurance and VAT, interpreting results from graphs in financial contexts, Retail and Consumer Price Indexes, currency exchanges, and budgeting. – Estimation using Fermi – Critical analysis where students must present logical and reasoned arguments in context, communicate mathematical approaches and solutions and critically analyse the validity of data quoted in media, political campaigns, and marketing. – Normal distribution and confidence intervals where we research the distribution and use it to find probabilities. – Correlation and Regression where we recognize if pairs of data are linked, calculate the Pearson Moment Correlation Coefficient and use the best line of best fit to make predictions.
