Skill Refresher: How to Calculate Rates and Proportions – 9/28/2017

Watch Video

Speakers: Michael Samuel, DrPH, a Data Scientist/ Senior Epidemiologist with the California Department of Public Health

Objectives:

Calculation and comparison of rates and proportions are basic skills for epidemiologists. We’ve all done so, at least in grad school, but may be rusty around the edges.  This basic webinar will review the fundamental concept of a rate and a proportion; review their calculation, including with confidence intervals; and review the assessment of trends in rates and proportions.  We will demonstrate the calculation of these measures using free web-based “calculators” and with a little bit of code using R.

After the webinar, participants will be able to:

  • State what rates and proportions are and why they are important
  • Calculate rate-related measures using free web applications
  • Calculate rate-related measures using R, that can be expanded for other “real world” production projects
