#### Datasets

Relevant datasets are occasionally linked within a lesson, so that you can use them in an external SAS program. Data sets that are stored as text files have a ".txt" or ".dat" extension, while SAS data sets have a ".sas7bdat" extension. We'll mostly just want to save the data sets to a specific location on our computers so that we can use them within the SAS application.

If you want to download and save the data set to a specific location on your computer, click the link and adialog box will appear and allow you to save the text file to the location you choose on your computer.
