You are living proof that there is a vast difference between a teacher and an educator. Teachers are everywhere but it takes something special to be an educator. Thank you so much for these videos! Thanks to you I have an A going into my final exam. My college prof was very confusing. Thanks again!!

You are by far the best Stat teacher i have come across!!

Best linear regression videos on the internat. Great intuitions will hopefully save me in my upcoming econometrics class! Thanks.

@laetitiamarie1 I have a stats website: apstatsguy (dot) com Check it out, and thanks for the kind words. I'm putting up a bunch of other videos soon. I've got about 25 up now. Thanks for viewing!!!

You, my friend, are more helpful than you will ever know.

I have possibly the most dull, non-ethusiastic teacher who doesn't know how to teach the class. I haven't learned a thing from him from all the 7 weeks I've been sitting in his class and I learned more than I ever have from you in 15 minutes. I wish you were my teacher! thank you!

Great job of breaking down an intimidating topic, and making it both simple and useful.

If your calculator does not show r, and r2 you can fix this by following these steps:

[@MrNystrom]

No. If the scatter plot is curved, then you would want to "fit" a curve to it. Strength has to do with the predicting power of an equation (model). If the scatter is tightly packed around a curve, the curve is a stronger predictor of the relationship than a a loosely packed scatter plot around a line.

I shared this on my wall and over 30 people watched it :)

i dont usually comment on youtube videos but im going to anyway because this video has managed to explain something to me which i was previously for the sweet life of me unable to understand! ... and i agree with the person bellow who suggested you do more ib topics, would be super helpful! (chi square!)

[@brandonpack4835]

Good explanation. I'm 34 and was still entertained by your humor in the vid. Thanks for sharing

[@spikeit914]

Thanks so much, its been 4 years since I took a math course and completely forgot how to properly study. This helped so much!

[@laninacook301]

You are an AWESOME teacher! Thank You

[@JackInAction]

I'll remember the pinky trick! :p

[@CallumPUrquhart]

Awesome video...make it very accessible

[@sumanpaliwal7838]

great teaching sir...actually m afraid of maths....lots of confusion is there but still trying to understand it because of u :) thanks

[@erowhon]

Thank You Sir for the inspiration. Stat is so hard, but if you put them into something that an ordinary person can understand, it gives a below average student dream bigger things that only nerdy-nerdy people can achieve. When I become a teacher, I'd like to be like you! =)
