    thank you so much Mr Mystrom. it was because of your videos I was able to graduate uni. my final subject was statistics, which mind you I had failed 3 times. it was my final subject. I got a letter saying that if I did not pass I would be excluded. watching these videos allowed me to finally understand and pass 😀😀😀😄😃😄😃😃😃

      @@MrNystrom I'm in the same boat as Tina. Your Videos helped me learn a semester's worth of statistics material in a couple hours. The professor that I had was hard to understand glad I tuned into your videos. Thanks so much for taking the time out of your day to do these videos. I will definitely tell people about your channel.

    FINALLY!!!! IT'S ABOUT FREAKING TIME!!! This guy is bona fide proof and evidence that not all teachers TEACH!!! This guy explained this segment of stats better than ANYONE that I've come across on the internet or on U-tube! I have become a front row student in this guy's class. Stats no longer seem as challenging!

    I am not kidding when I say I spent 14 hours on one 6 questions homework assignment and still did not understand it. In five minutes you have clarified more than any book, instructor or other RUclips video I've seen. I may actually pass statistics now! THANK YOU!!!!

    oh oh OHHHHHHHH, I think I actually get it, you're one hell of a teacher man. Why I didn't I find you at the begining of the term! well, there is still my next stats level course. I'm in MTH243 and it's been kicking my butt all around the room without letting up. Watching your videos has taught me some stats-fu so I can actually defend myself!
