Defining Statistical Data in Lists
Statistical plots (stat plots) are graphical representations of
data that has been stored in lists. Therefore, since you need to
create your lists before you can define stat plots, review
Chapter 5: Lists for information on naming and creating both
numerical and categorical lists.
Note: All examples in this chapter assume that you know how
to enter lists in the List editor.

want them displayed with your stat plots, deselect all defined
functions with - }
