Purpose

NHANES data files are available for download from the website as SAS transport files (.XPT). To use these files you need to create a directory to save them, download the data files and documentation, and then extract or import the datasets.

 

Task 1: Create a directory

You will create a directory to save your data files, documentation, and extracted SAS datasets. This will help keep your transport files and datasets organized.
