NHANES Environmental Chemical Data Tutorial

Survey Orientation

The Survey Orientation course consists of four modules:

            Module 1: Environmental Chemical Data Overview

            Module 2: Navigate the NHANES Website

            Module 3: Environmental Chemical Data Structure and Content

            Module 4: Overview of NHANES Survey Design and Weighting

If you are new to NHANES 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 though when preparing an analytic dataset. 

If you are an experienced analyst who needs only specific information to help you complete an analysis on your own, you can pick and choose topics of interest from the navigations bar to the left.  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.
