tbilljj
In Example 1.17 (page 17) we used a back-to-back stemplot to compare the T-bill rates for the months of January and July. Figure 1.15 gives side-by-side boxplots for the two months generated with JMP. Notice that this software plots the individual observations as dots in addition to the modified boxplots as default options.
