8 mins beats my 3 hrs course, very helpful n thank you!

Einstein said if you couldn't explain something in simple terms, you didn't understand it well enough.

Thanks for your clear delivery of concepts that could be quite baffling.

Posted this 8 years back and people are still benefiting from it! Awesome work!

I've never watched a maths/stats video which was so CLEARLY EXPLAINED before...in my ENTIRE LIFE.
Amazing video making skills sir!

Mr. Longstreet, I beg you to publish a statistics textbook. If you title it "Study less, party more, and get good grades", I'm sure it'll be on every Top Ten bestsellers list! Thank you so, so, so, so very much.

That is a great question. In my lectures I don't emphasis the equations much or how to do calculations by hand. It is important that students understand basic principles though. Such as a regression line goes though the mean of the independent and mean of dependent variable. The point of regression is to help understand correlation and more important causation.

I believe it is much more important to understand the meaning of the output than how to plug and chug with a formula or a tool.

Clean, clear and crispy. I'm glad people are still out here doing things manually instead of immediately hecking off to code. bravo, SF

so helpful us failing university students thank you

This was without a doubt the best explanation I've ever experienced on this topic.

I literally do not understand why some professors struggle to explain concepts in 3 hours as well as you do in 8 minutes. You make it seem so goddamn easy I feel like I'm cheating just watching this video 💀💀

This is the only video I could find that explained how to actually use the formulas, thank you!

Me: What’s up with these funky symbols and equations UGH

*sees video*
Me: ...That’s it?

Pure genius! This is my third time to take Statistics and don't have a clue whatsoever about it. I read a lot of easy books to understand it, watch videos and tutorials but to no avail. I watched your videos once and I was hooked! Boy, I understood it in one sitting! Your calm voice and clear/simple explanations plus your awesome graphics/animations just makes it all so EASY to understand. Plus of course your knowledge about what you're talking about.

Thank you so very much!You're amazing

[Ornitholestes]

This is absolutely amazing! I tried to understand this method from written instructions with my limited mathematical skills and failed over and over again. Then I watched this video once and it's perfectly clear!
I need a maths teacher like you!

[kandyslarsen]

You actually made my life so much easier. I may actually get an A in statistics because of your videos!

[statisticsfun]

Your comments are much appreciated! Yes education is a great and wonderful thing and my plan is to keep making free educational videos.

[abokbeer]

I spent couple of minutes wondering how can I thank you. Simply thank you

[munishgupta]

You have no idea what a great work you are doing sir. I just spent 10 days to understand regression theorem but nothing went inside my brain and your 10-15 minutes video cleared all my doubts.
God Bless You.
Keep doing such humanitarian work.!!

[luna-svuf]

I hope you get paid for this because otherwise my heart cannot handle that you put so much effort into all of these videos, even if you do it proves there are good people in the world. love you even though I don't know you!

[statisticsfun]

Thank you for the compliment, it is much appreciated. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.

Good luck in your classes too.
