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!

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.

this may sound like a dumb question and i´m sorry if that´s the case, but why can´t the chi square distribution take the value of 0? i ask this bc the standard normal distribution can in fact take 0 as a value which means that chi square should be able to take 0 as a value, what am i missing?

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.

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!

Thank you so much for your video! This is very much helpful! Could you answer my questions? I still have hard time understanding why the q value goes to infinite at 0. If it's z^2, shouldn't it be finite since z has also a finite value at 0? I also want to know why the max value of q2 is smaller than that of q1(which is infinite). In my intuition, z1^2+z2^2 should be bigger than z1^2 however small the values are. I think I'm definitely missing something out. I'll appreciate it so much if you could answer them :)

Hi Man, Unfortunately I was unable to follow why 3 degrees of freedom have a larger value across 1. something. Standardized Normal distribution have the highest value at 0, then once we square the values 0 will remain the highest and adding would still make the value across 0 highest, how come the change in curve? Also, as per my understanding if I square a distribution, it means squaring the Random variable only and the underlying probability for it shall not change. @zedstatistics Need your help.
