Understanding the 3 P's: Power, Precision, and P-values

Date: Wednesday, December 04, 2019

Time: 9:00 AM To 11:00 AM

Location: Price Center, Room 351

Event Description:
New health studies appear in the news and medical literature every day. But how do we critically assess whether the latest drug or intervention is actually effective? Understanding crucial statistical tools for evaluating the level of evidence in scientific research results is the key. Researchers must understand how to interpret the "P-value," a statistical measure of significance in hypothesis testing. It is a slippery concept that people often misuse and misinterpret. Similarly, knowledge of Statistical Power is necessary as it enables researchers to detect differences between the groups they are studying, making sure they do not "miss" biologically or clinically important signals due to underpowered studies. Finally, Precision refers to how close estimates from different samples are to each other and is a measure of the degree of uncertainty in a study's results. Understanding these concepts when reading the literature or undertaking your own research project is critical. Mimi Kim, Sc.D., Professor in the Department of Epidemiology and Population Health, and Division Head, Division of Biostatistics at Einstein, will explain these fundamental concepts and, using examples, show how they are applied to studies.

Target Audience:
All faculty.
