Discover three considerations that are important when choosing to use weight provided in the BRFSS data set for a descriptive analysis.
- [Narrator] Hi there.…We are on a little detour from our main project here…for chapter six, section one.…So I can show you…about using BRFSS weights…in a descriptive analysis.…Here, I teach you about three truths…about using the BRFSS weights in an anlaysis.…So this topic will be mostly philosophy, and a little code.…Everyone who talks to me about BRFSS always starts…by saying they need to understand the weights.…
How do you use the weights?…Why do you use the weights?…When do you use the weights?…And the reality is, you hardly ever use the weights.…That's what I'll explain philosophically.…In the next section, I'll do a descriptive example,…where we actually get to use the weights.…So, I'm sorry to get heavy on you,…but we have to talk about epidemiology now.…In epidemiology, some people care more about populations,…and some people care more about samples.…Who cares about populations?…Well, the health department.…
The CDC.…That's because they have to allocate resources…to dealing with exposures that are common…and that cause a lot of disease.…
This detailed, practical course is designed to help those in the field of public health, medicine, and data science to edit, analyze, and interpret data. Learn how to code new variables, use the forward-stepwise modeling process, and document your decisions. Find out how to visualize results by generating charts and graphics, and how to add tables and figures to your documentation. This course helps equip you to independently design, develop, and execute a full BRFSS analysis, and even publish your results in scientific publications or journals.
