  1. Unit 3 –Problem Solving AO5 –Create suitable graphs and charts D Garey

  2. Graphs/charts • Choose 3 different types for DISTINCTION • Do not discuss what each graph shows at this point • You MUST justify your choice of each type of graph • Don’t touch line graphs unless you have continuous data! D Garey

  3. Pie Charts • Good for showing percentages • Easy to read • Very visual • Not so great for comparisons • Make sure they are fully labelled, with values D Garey

  4. Column Charts • Clustered column is better for comparing values across categories • Stacked column –compares the contribution of each value to the total in the category D Garey

  5. Scatter Plots • Compares pairs of values • Line of best fit can signify a correlation –positive and negative depending on trend • “-er” statements can be made i.e. the older the person the less time spent on the Wii D Garey
