How To Understand Covid-19 Antibody Testing Accuracy | Intuition for False Positive and Negatives
How accurate are Covid-19 Antibody tests? Labs that run these tests claim that they are 95-99% accurate, but are they really? In this video I help unpack the way any diagnostic test should be assessed and show that these tests, in particular, are FAR less accurate than you might think. You'll learn all about False Positives and False Negatives, get the intuition behind Bayes' Theorem, and learn how to use these ideas just for Covid-19 testing, but for any kind of test.
I'm Jeff Galak, PhD, and I do this all without ever using any fancy jargon or any complex math. I focus on intuition and and insights to help you get an intuitive understanding of complex, important, and timely topics in statistics, data science, and data analytics.
