## Box Plot/Mosaic Plot

The *box plot* is a stylized representation of the distribution
of a variable, and it is shown in Figure 38.19.
You can also display mosaic plots for nominal variables,
as shown in Figure 38.37.
In a box plot, the sample mean and sample
standard deviation computed with vardef=**DF** are
used in the construction of the mean diamond,
as shown in Figure 38.19.

If you select a **Weight** variable, a weighted box plot
based on weighted quantiles is created.
The weighted sample mean and the weighted sample standard deviation
of an observation with average weight for vardef=**DF**
is used in the construction of the mean diamond.
