Comments on: Itâ€™s been a long time since I studied statistics. Remind me, what does a p value represent?

Thu, 22 Sep 2011 04:14:46 +0000http://effectsizefaq.com/?p=65#comment-1610You are very sharp-eyed to pick this up. Well done! The line in the book was flagged by one of my reviewers as being potentially misleading and in one sense it is. As I indicate above and elsewhere in the book a statistically significant result is one that generates a conditional probability value that is lower that certain conventions given a bunch of assumptions pertaining to the null and other things. But it gets a little tiresome to have to say all this every time you discuss the meaning of statistical significance. The point I was trying to make on p.4 is that statistical significance is not the same as practical significance.
