Welcome!

Welcome to the first in-depth lab that complements the course "Data Analysis and Statistical Inference" given by Mine Çetinkaya-Rundel on Cousera.

The Behavioral Risk Factor Surveillance System (BRFSS) is an annual telephone survey of 350,000 people in the United States. As its name implies, the BRFSS is designed to identify risk factors in the adult population and report emerging health trends. For example, respondents are asked about their diet and weekly physical activity, their HIV/AIDS status, possible tobacco use, and even their level of healthcare coverage.

We will focus on a random sample of 20,000 people from the BRFSS survey conducted in 2000. The .Rdata file can be found at http://s3.amazonaws.com/assets.datacamp.com/course/dasi/cdc.Rdata.
