Explain that the histogram classes should be centred on 0, 1, ... rather than being (0 to 1), (1 to 2), etc.

Use the slider to change the histogram into a bar chart.

Explain that a bar chart is better than a histogram since it highlights the discrete nature of the data.

The data set shows the numbers of hurricanes in the North Atlantic each year from 1910 to 2009.
