Kevin, Bare in mind this article was written as a follow up on another article that amply describes the concept of statistical power. I think a comparison between the two is justified. Both are about the use of additional information to enhance decision making and both are obviously difficult to grasp. There is a conceptual resemblance between the problem many scientists had a long time ago understanding the dynamics of the probabilities involved in the Monty Hall Problem and the problem many marketing data analists have nowadays trying to understand the dynamics of statistical power when designing experiments. The practical resemblance between the two is that failing to apply the logic behind the Monty Hall Problem will make you throw away half of what you could have had. Not applying the logic of statistical power makes many data analysts and thus organizations throw away half the knowlegde they could have had. Apart from the resemblance between the two puzzles, the practical consequences of such misconceptions are quite worrying to say the least. It’s for that reason I make these efforts to explain the matter. Regards, Kees
