Patches give cold turkey the bird

The horizontal bar graph representation in this article is what makes it particularly useful for students to study when they are beginning the topic of graphical interpretation. The lengths of cigarette bars are not proportional to the percentages represented and the graph is very misleading. Further the percentages in the graph add up to 112.3%. This may indicate that smokers use more than one technique to quit at the same time. This point, however, is not clarified in the article. Students could be asked to prepare a graph which presents the data accurately. They could also be asked to produce a bar (or other) graph to show the percentages of Australians who have quit who come from each state. As these percentages sum to 87.8%, they could also explain where the other quitters came from.
