    I have no formal education but that's only because the Grateful Dead used to tour. Now that they're long retired I have a bit more free time to flail about in many advanced fields. What I've discovered is there are certain teachers that can make the most fascinating, mind blowing subjects as engaging as watching paint dry. Then there are teachers that can take a subject that, at first glance, has the appeal of eating mouthfuls of dirt, but after a few moments you realize you're gripped with increasing excitement. You are the latter. I know I'm late to your channel and blog, but I hope you continue on. You are very helpful, illuminating and funny! You had me at puppies but I lost it at "8 year old are evil." Who woulda thunk statistics could be so fun? THANK YOU.

    Wow! You think you were taught p-value badly. I was just told a formula to calculate it and compare it to 0.05 for some reason to accept or reject the null hypothesis. I am glad I don't do stats for a living. However, it would be worth wondering that with the base knowledge that I got, could I ever be a statistician in my life!? I think my course's name should have been "How to pass the stats course but fail life 101"

    Chicken or egg problem / Dealer's choice I reckon, oh yes I do, because, duh, duh, duh -- If you understand the purpose and use of null hypotheses before attempting to convey p-values vis-à-vis to them, _and_ have some basic understanding of probabilities then it seems to me you're well on your way to estimating something somehow.

    Okay, you said the p-value is a probability that the result is that ridiculous in a world where the dog didn't do that. But I hear statisticians tell me all the freaking time that the p-value is NOT a probability. So what am I getting wrong here? There are so many conflicting statements about that goddamn p-value I don't know where to start. I just see it as a tool to distinguish the signal from the noise with some sort of confidence, not more, not less.
