Can be extended if you pose questions on using the line of best fit to estimate one variable given a value for the other. Interpret scatter graphs in terms of the relationship between two variables Know that extrapolation might not be reliable Understand that correlation does not imply causality Use the line of best fit to make predictions Construct cumulative frequency tables Interpret box plots to find median, quartiles, range and interquartile range and draw Fractions, percentages, ratios 20 3.1 Fractions 20 3.2 Percentages 21 Mathematics / Data and statistics / Data processing, GCSE Maths: Statistics lesson - data cards, Plotting Graphs, Anomalies and Calculating Mean, Probability 4 - Experimental Probability (Relative Frequency). For better or worse, budget forecasts are based on these assumptions. Draw and interpret scatter diagrams; Identify correlation (eg “strong negative”) Draw a line of best fit and use to predict values; Predict correlation (including strength) from real-life examples when data not given (eg house price with distance from London) KS3 Maths Curriculum Area.
