The practical examples used later in the textbook are based on the collection of datasets and programming code found in the “Textbook Materials” Folder, which you can download from the book’s website at http://support.sas.com/publishing/authors/lee.html. There are different versions of the folder depending on whether you are using SAS 9 or SAS Studio.

As we learn to use SAS in this chapter, part of our job is to learn to use the datasets and code from this folder.
