The Outliers option prints the top five highest and lowest values, and what case they are associated with. (If you have specified a "Label cases by" variable, that variable will print instead of the case number.)
Factor levels together will create separate graphs for each continuous variable. If a factor variable is specified, those groups will appear within each boxplot.
The Percentiles option produces the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles of the data.
Dependents together will put the boxplots of each continuous variable on the same graph. If a factor variable is specified, those groups will also appear within that boxplot.
