I never, or rarely comment on youtube videos of people teaching something, but I've been using a lot of your content to try to understand the basics of stats and probabilities, and your content is simply awesome. Really good explanations, voice is clear and friendly, you give the student the will to learn and it's really awesome. Keep it up ! Love from Paris

@rachaelmc 4 года назад

You are so good at teaching. You make everything so clear in such less time than other videos. Thank you so much!!!

@Godly-Warrior-SebKing1213 2 года назад

A little bit of a nitpick, you said at one point "we accept the null hypothesis." I am not incredible at stats but I do know that you can NEVER accept the null, you can only reject or fail to reject it.

@jarodchesser1881 Год назад

I'm in a research course in grad school and am barely staying afloat, mostly because the instructors and materials just throw a wall of jargon at us with, apparently, the expectation that learning these concepts would happen either magically or by osmosis or something. It's like they're trying to teach us a foreign language by giving us books written in that language and then flunking us for not being able to do literary criticism in that language after a week. It's ridiculous. I've got multiple degrees, speak multiple languages, have worked around the world, but they act like we're dumb because instead of teaching, they just expect that what seems obvious to them will be obvious to everybody. This one video is the only resource I've found that breaks it down to a level accessible to those not already part of the "in-group" of trained statisticians. THANK YOU. Is it really that hard to just say, this is what it is, this is what it's for, and this is a quick look at how it works? EVERY other resource I've found either gets lost in this self-referential loop of jargon being explained with jargon; or else it takes 3 hours to explain what could be said in 2 minutes. I've subscribed and will probably spend my study hours here instead of with the useless course materials I was provided.

@legoldmanofficial8944 7 дней назад

@TheScottDub44 3 года назад

I am taking Graduate Statistics right now through an online course and this gave me better insight than any material provided by the school so far. You also did it in a fraction of the time in comparison to other videos in a way that made sense. I'll be following for future videos. Thank you.

@daddychan7 7 месяцев назад

Great video! One correction though... around 6:10 you state that we will accept the null hypothesis, but it is important to distinguish that we NEVER accept the null hypothesis, we only fail to reject it.
