Learn the features of a descriptive BRFSS analysis, and how BRFSS weights can be used to make population-based estimates of frequencies.
- [Instructor] This lecture is going to explain specifically…what is meant by a BRFSS descriptive analysis.…First, I want to share with you…how I conceptualize approaching a BRFSS analysis.…I divide them into two main types,…descriptive and analytic.…This section will describe the descriptive approach.…In the next section, we'll describe the analytic approach.…Descriptive analysis just describes…the rates in the population.…Only it's not so simple,…because remember,…the CDC has a very complicated sampling approach.…
The goal of the sampling approach is to be able…to weight the final data set out…to make a population-based estimate.…In fact, I'm literally talking…about using the data fields present…in the data set called the weight fields.…Just to quickly remind you how weighting works,…I'm going to show you how I weight the various components…of the final grade I give in the statistics class I teach…at Laboure College in Milton, Massachusetts.…You will see that the weights add up to 100%.…That's also true of the BRFSS weights.…
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.
- Reviewing survey data and documentation
- Conducting a BRFSS analysis
- Understanding naming conventions
- Editing variables
- Reviewing distributions
- Generating an analytic dataset
- Developing descriptive statistics to answer prespecified hypotheses
- Preparing publication-worthy tables and plots
