The feedback I received on “How large should your A/B test sample size be?” inspired me to write this new post. The goal is to demonstrate that indeed probability can be a tough and even counterintuitive concept, but once understood and applied it can yield tremendous advantages. This post is about what has come to be known as the ‘Monty Hall Problem’. Image from Wikipedia This is the situation: you are a contestant on a [...]

And many experiments are done indeed, the result of which are interpreted following the rules of null-hypothesis testing, “are the results statistically significant?”.
