The Problems With P-values

Think you understand p-values? We thought we did too. We were wrong. A huge number of us have been taught incorrectly. Thanks to Dr. Brian Alper, Editor-in-Chief of DynaMed who brought this to our attention and who, with some other writers, helped us work through the brambles. See our new definitions and explanations of “p-value” and “confidence intervals” in our glossary on our website. We have also added some thinking about “multiplicity testing.” Our tools have been updated to reflect these changes so you may wish to download your favorites for validity anew. See also our recommendation for DynaMed.
