My recent Decoded Science article, “Detecting or Avoiding the Yule-Simpson Paradox“, deals with a surprising puzzle that may occur when comparing two competitors under different conditions.
A Cut-and-Dried Example of a Yule-Simpson Paradox
The chart above compares the success rates of two fictional surgeons for scheduled versus emergency operations. Dr. alpha has a higher success rate in each situation; but Dr. beta‘s overall success rate is higher. That, my friends, is a Yule-Simpson Paradox, or Simpson Reversal.
My article explains the math of the Yule-Simpson Paradox, with some examples of how the situation may arise.
There’s a practical side, too, whether you’re a marketer planning an A/B experiment; a patient trying to decide between competing doctors or medical treatments; or a student weighing educational programs.
