The Preparing an Analytic Dataset course for NHANES II includes four modules:

Module 4.  Locate Variables
Module 5.  Download Data Files
Module 6.  Keep & Merge Datasets
Module 7.  Clean & Recode Data

If you are new to NHANES II data analysis, we encourage you to approach these four modules in sequence. By choosing to go sequentially through the different tasks and steps in each module, you will follow an order that resembles the real life process an analyst goes through when preparing an analytic dataset. If you have not analyzed NHANES data before, please complete the basic tutorial covering continuous NHANES before beginning this supplemental tutorial.

If you are an experienced analyst who only needs specific information to help you complete an analysis on your own, you can pick and choose topics of interest from the navigation bar to the left, or from the Tutorial A-Z Index.  You may also go to the Sample Code and Datasets page to download and modify sample programs and datasets for your own use.

Sample Code

Annotated SAS and SUDAAN codes are presented in summary tables throughout the tutorial for the sole purpose of demonstration and explanation. These annotated codes do not comprise a complete SAS or SUDAAN program that can be readily submitted for a computer run. If you need the complete SAS or SUDAAN program corresponding to these annotated codes, please consult the 'Download Sample Code and Dataset' links listed under the tasks in the respective module.

More Information

The computer software, knowledge, and skills requirements are listed for your convenience on the Software & Technical Requirements page. The Tech Tips page can help you troubleshoot if you run into technical difficulties. Before beginning the course, please see the Jump Start Guide for more information about how to use the tutorial and its features.
