The Survey Design Factors course includes three modules:

Module 10. Sample Design
Module 11. Weighting
Module 12. Variance Estimation

These three modules provide an overview of the design features for the Continuous NHANES samples, as well as how to correctly account for these design features in analyses.

The Sample Design module describes the complex sampling design of NHANES, which includes multi-stage, unequal probability, and cluster sampling methods. This module also explains how to specify sampling parameters in an analysis.  The Weighting module describes how NHANES weights are calculated to take into account survey nonresponse, oversampling, post-stratification, and sampling error. More importantly, this module teaches how to select the correct weights for an analysis. The Variance Estimation module introduces methods to calculate variance estimates and degrees of freedom.

These modules will provide analysts who are new to NHANES with an in-depth knowledge of the survey™s sampling and weighting procedures and basic tools for calculating variance estimates.

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.
