Misleading Graphs - Answers

Graph 1

In the graph on the left, the y-axis is not set to 0.  This makes the difference in tax cuts, less than 5%, seems larger than it actually is.  If the y-axis is set to 0, as shown on the right, the tax cuts appear much more moderate.

 

Graph 2

In the graph below, the axis for Smoker Probability of Death is different than the scale used for Nonsmoker Probability of Death.  One goes up to 100% while the other only goes up to 40%.  This makes it look like they have similar probabilities of death, though the smoker probability is 60% and the nonsmoker probability is less than 30%.  Both axes should be scaled the same.
