Saturday, November 16, 2019 - The Monty Hall problem and other wonders of statistics and probability

Time: 2:00 PM
Location: Community College of Philadelphia, Room C2-28 Details
Speaker: Dr. Michael LeWitt

This talk is a discussion of some of the statistical measures which apply to the analysis of medical information, including the efficacy of tests, medications, and treatments.  It is an area that is poorly understood by people who need to apply this information to the care of patients.  It is applicable to many other aspects of daily life, with relevance for all of us who need to make informed decisions on factors which involve our well-being.  The Monty Hall problem, which is a subset of the lecture, is a fascinating concept which continues to vex the most learned members of our society

Dr. Michael LeWitt is retired from 40 years in Emergency Medicine, and is a founding member of two emergency medicine residencies, (Philadelphia, and Johnstown.) He teaches structured medical courses in Philadelphia and Chicago, has lectured locally, nationally, and internationally, and authored several articles in medical journals.  He has also assisted PhACT in judging projects and awarding prizes at the annual George Washington Carver Science Fair.
