In our Briefing this week, we revisit a topic we looked at a while ago, the epidemiology of gang activity in El Salvador, and look at the impact of Covid. Our spotlight is on:
Oct 30 – Nov 27: Sample Size and Power Determination
See you in class!
Gangs and Covid
Some time ago, I chatted with Dr. Carlos Carcach about how epidemiological and cancer models might help us understand the activity of gangs in El Salvador. Re-reading that blog made me wonder how an actual epidemic has affected gang […]
Headline of the Day
Biology and Behavior Put Men at Higher Risk of Dying
(Washington Post, 10/19/20)
The headline suggests the tantalizing prospect of immortality, but the story itself disappoints, making clear that the Post is talking about dying from Covid.
Student Spotlight
Suma Krishnaprasad
Suma Krishnaprasad was the first data scientist hired at Cleveland Clinic Abu Dhabi. She works to develop and deploy predictive models, and also to provide statistical design and analysis for dozens of clinical trials and other research projects. She came to the Institute for Statistics Education initially for a number of courses in biostatistics, then enrolled in the Analytics for Data Science certificate program. She came to us to refresh her statistical knowledge, to better position herself in her pioneering role at the Clinic. Among the courses she took was our Sample Size and Power Determination course, which helped her understand when to apply which technique, and gave her greater confidence in calculating sample sizes for the Clinic’s studies.

Oct 30 – Nov 27: Sample Size and Power Determination
How many cases/subjects should you have in your study? The answer depends on several factors:
- How big an effect you are looking for
- What level of power you seek
- What significant level you seek
- How much variability there is in the data
Learn how they interact with each other, how to specify their values, and how to use those values to calculate sample size.
Certificate Spotlight
Biostatistics
This online certificate program in biostatistics and epidemiology provides the skills needed to gather, analyze, and assess data for activities like clinical trials, medical research, and public health studies. This ten course program – including seven required courses and three electives – covers the critical statistical concepts used in medical and health sciences.
This certificate offers a path to college credit – via the American Council on Education – to other institutions in the U.S. It offers approximately 28 credits in this way; compare to a Master’s degree program in biostatistics.
