This video describes the why, the what, the how, and the when of the chi squared test. Why would you use it, what does it show, how do you calculate and interpret the value, and when you would use it. Oh, and there is chocolate!

I'm very thankful for this video! I've been searching in the internet about why, how, and when to use chi-square but I really can't understand any of it bcos my mind can't absorb anything related to maths/statistics and I'm losing hope in what will happen in our study. Good thing I found this video and it gave clarity to me. Thank you so much, sir!

Best explanation of why "degrees of freedom" is called what it is; something I've sought for a quite a long time. Please excerpt that little section and put it in a video called "degrees of freedom explained." I'd have found that cool explanation years earlier.
