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
