Using the Explore procedure, you created a summary table that showed the mean alfatoxin level to be unsafe for five of eight corn yields. You also created a boxplot for visual confirmation of these results.

Boxplots provide a quick, visual summary of any number of groups. Further, all the groups within a single factor are arrayed on the same axes, making comparisons easier. While boxplots provide some evidence about shape of the distributions, the Explore procedure offers many options that allow a more detailed look at how groups may differ from each other or from expectation.
