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. This course 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.
