    I've watched 7 videos of the distributions series at a stretch and I'm absolutely delighted! I have never watched any statistical videos explained in such details, yet made so intuitive. Amazing work! Please keep these coming.

    Woah, I never expected that acknowledgement of Indian viewers at the end. I must tell you that I see your videos and always get totally amazed by the way you explain things, I always wanted my professors to focus more on intuitive side of things but then your videos fill that void. And yeah, I am from India and would 'really' love to meet you one day. Your fan!

      Thanks so much for this, Mudit! One day I hope to travel to India though it looks like those plans are on hold for a while. Wishing you safety and health in these strange times!

    The timing..... I started studying this distribution at uni (online) today, your video appears on my feed today.... Thanks for your videos btw, they have been so helpful.

    Hello, Mr. {Justin}. It appears that I found your teaching resources {just in} time - slightly over a month before the end-of-semester examination. Your teaching is life-preserving. Most intriguingly, the way you teach mathematics is like how a literature professor would disassemble and compartmentalise a Shakespeare play in a university English course. Very interesting and thought-provoking choice of words. I will surely recommend your videos to siblings, relatives and friends...

    Dear ZED, This tutorial came just ON TIME between my statistix course last year 2019 and this semester 2020. CHI square, the way you teach it, is suddenly MADE CLEAR like magic. i can say now that I understand the distribution. all I need is to watch the other chi square usage tutorials and make sense of the test . again, many thanks. highly recommended.

    Justin, since you specifically asked __not__ to look into Pearson's social ideas, I had to (we've all descended from monkeys, haven't we?). Yep, not worth looking up. :)
    But seriously, great videos. It has been years since I finished college, and have not been using my brain so much in my career; recently joined a Data Science course, and even though everyone keeps telling me just the surface of stats and maths is enough, it doesn't satisfy me. Your videos (and a few others) help me gain a good insight into the subject, and I simply love it when suddenly something strikes me and I start understanding stuff! You make RUclips a good place! :)

    I am a great fan of your videos and really impressed by the outstanding teaching ability. I have a doubt with Chi-square distribution. First why we are squaring the z value to get Chi-square? Why we are taking about degree of freedom in chi-square distribution, but not in normal distriubtion? Also, why we are using chi square to find the goodness of fit and finding the association of attributes. If you could explain using a practical example, it would help us to understand. Thanks.
