    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!

    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.

    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.

    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.

    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...

    Explaining the intuition behind make it so interesting. I don't know why you do that, maybe pure altruism? Share your passion for stats? you're delivering so much value in those videos that you deserve a golden medal. All I can say is thank you.

I will really appreciate videos of survival analysis, ROC curves, interpretation of literature in ophthalmological field.

    This is really cool, I love the fact when you say that you hate "Formulas", trust me Ihave come across very few curious souls like you, who doesn't not settle on a given formula but want to understand "Why"
    You are are helping a lot pf people develop their intuitive streak, please keep it up. Stay Safe!!

    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.

  • @DDranks

    I haven't seen it spelled out anywhere in these tutorials that arithmetic on random variables (such as sums of distributions, squaring a distribution etc., which are quite relevant here) DO NOT behave like the point-wise arithmetic on PDF's of those random variables! For example, after hearing that the Chi-Squared distribution with DF=1 is "a square of the Normal distribution", one might go to Google and type exp(-x^2)^2 to see if it's true. That is absolutely not the correct distribution, as we can witness by comparing it to the one seen on this video. Zedstatistics, I'd love to see a video about this!
