Quote of the Week

Question #1: P-Values

When you all where talking about the full moon and suicide study last week kara said that “p-values as we know are pretty mean goes as they tell us a little bit more about the analysis than the actual (pause). That’s why effect sizes matter”. Could you please elaborate on this and the sentence kara stop herself from finishing accidentally?
