Step 1. If you are new to the NHES, visit the NCES Distance Learning Dataset Training for an introduction to using the NHES and other NCES data sets.
Step 2. Examine the questionnaire to determine the relevant items and their associated variable names for your planned analysis.
Step 3. Review the data file user's manual, paying particular attention to the chapters on data considerations and anomalies, weights and standard errors, and derived variables. Derived variables are created from composites of questionnaire variables to aid in data analysis.
Step 4. Review descriptive information about relevant variables in the codebook. The codebook includes value labels, frequency counts, and percentage distributions for all variables in the data file.
