Task 1: How to Select the Correct Weights for NHANES I Analysis

To select the correct weights for NHANES I data, you need to first check all variables in your analysis and select the weight of the smallest analysis subpopulation. There are six options.  These are the full sample weights for stands 1-35 or 1-65, the detailed sample weights for stands 1-35 or 1-65, the Augmented Survey weights for stands 66-100, or the combined detailed/Augmented sample weights for stands 1-100. See the Table below for the correct weights for each component.
