Create a report that summarizes and visualizes data that evaluate a topic of your own choice from the National Health and Nutrition Examination Survey (NHANES).
Section 1: Determine one category in “Laboratory Data” that you
want to analyze
◦ Read the description of variables and search for information about how those
measurements are used to assess individuals’ health (and maybe how the measure is
calculated, if of interest and if not too complex)
◦ For example, you may pick Metals – Urine
Section 1: Search for references
◦ How the categories/variables are used in
practice
◦ For example, a certain measurement is
used to diagnosis certain disease or
screen for organ failure
◦ Write an introduction describing the
variable and your topic you want to
examine
◦ Cite the reference accordingly
◦ Do not copy-and-paste
Section 2: Data preprocessing
◦ Need to combine data using “joins” syntax
◦ For example
◦ Demographics + Laboratory
◦ Demographics + Examination
◦ Examination + Laboratory
◦ Laboratory + Questionnaire
◦ Determine the types of your variables of interest
◦ Check how many missing values are in your variables of interest
