Abstract:
|
The world is awash in p-values. Most introductory statistics courses spend a lot of time helping students understand how to find a p-value, and a good deal of time on thinking about what a p-value means (and doesn't mean). But we almost always know that the null hypothesis is false; what matters in practice is the size of the effect. Effect sizes are just as important as p-values but receive little attention. That should change.
