The Survey Orientation course includes three modules:

    Module 1. Survey Overview
    Module 2. Navigate NHANES Website
    Module 3. Data Structure & Contents

These three modules provide a general overview of the Continuous NHANES survey conducted since 1999, its website and data structure. NHANES contains a vast amount of data that is organized and released in separate data files on the NHANES website. These data files are organized according to certain conventions. Therefore, a thorough understanding of how information is laid out on the NHANES website and how the data files are organized will help you be more efficient in finding the information you need for your analysis. 

Whether you are a novice or an experienced analyst, we recommend that you review this entire course before starting the tutorial, as these three modules serve as a roadmap that will help you get oriented quickly or refresh your knowledge of NHANES.
