Choosing chart types – misleading graphs

MathematicsStatisticsAges 13–14

The same dataset is drawn as a bar chart, grouped bar chart, line graph, and pie chart. Students switch chart types, drag the top of a bar to change the values, and drag a slider so the y-axis does not start at 0 to see how much the difference gets exaggerated. The simulation comments on which chart type fits the data and flags misleading graphs.
