I wasn't claiming he was harder on the students. I was claiming that there is absolutely no evidence he was popular because he gave out easy As. So you're agreeing with me.
And I brought to you a non-anecdotal, total-population statistic. Again, justifying the null hypothesis (that there is no evidence he was any harder or easier on students in the grade distribution).
(more specifically: we weren't arguing about my first assertion, we were arguing about my second assertion. So the fact that you're trying to refute my second assertion, that there is no evidence he have out A's more freely, by attacking my first assertion, is irrelevant. I fully acknowledge that absent the department's response, we don't have the full picture of whether or not the department's issue was with the actual teaching content, but that was not what you and I were discussing)
