You are a member of a community workgroup that is investigating the usefulness of outreach programs targeting community groups in your county to receive seasonal flu vaccine. You have a readily accessible Behavioral R database from the Behavioral Risk Factor Surveillance System (BRFSS) database from the Centers for Disease Control and Prevention. The database contains the following information on each individual seen at a healthcare facility in your county over the past month: unique identifier, age, sex, race, ethnicity, flu vaccine, vaccine type, and zip code. If you could choose the form that each type of variable took what would you choose (nominal, ordinal, interval, or ratio) and why? Before analyzing the data what type of descriptive statistics would you like to see for each variable (if any) and why?
