The Preparing an Analytic Dataset course includes six modules:

Module 4. Locate Variables
Module 5. Download Data Files
Module 6. Append & Merge Datasets
Module 7. Clean & Recode Data
Module 8. Format & Label Variables
Module 9. Save Dataset

If you are new to NHANES data analysis, we encourage you to approach these six 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 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.

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.
