Abstract
There is wide agreement that P-values are over-used. 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). What matters in practice is the size of the effect. Effect sizes are just as important as P-values and should receive more attention.
