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 NHANES III samples, as well as how to correctly account for these design features in analyses. However, these modules are intended as a supplement to the Continuous NHANES tutorial Survey Design Factors course. It is assumed you have previously reviewed these modules.
The Sample Design module describes the complex sampling design of NHANES III, 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 III weights are calculated to take into account survey nonreponse, oversampling, post-stratification, and sampling error. More importantly, this module teaches how to select the correct weights for an analysis. The Variance Estimation module offers a brief comparison of NHANES III and continuous NHANES on methods of variance estimation, estimate stability and sample design, variance units, then refer you back to the main tutorial for detailed instruction.
These modules will provide analysts who are new to NHANES III with an in-depth knowledge of the survey's sampling and weighting procedures and basic tools for calculating variance estimates.
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.
