When you choose to create a new data table from the Welcome (File..New) dialog, you can start with a blank table or with tutorial data. The tutorial data comes with explanations and is a great way to learn how to use Prism.

Note that these tutorial data sets exist only to help you learn Prism. Choose the t test tutorial data set if you want to learn how to do a t test with Prism. Don't choose it if you want to analyze your data with a t test.
