Chi Squared Test

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!

[@garagelifestyle]

Actually someone who thoroughly understands this enough to be able to explain it... so good.

[@ishanapun1095]

Degree of freedom...wow...such a good explaination....😄😄

[@zeeshankamal3186]

Exactly

[@muhammadabidaslam8523]

Been into stats for a year,,, couldn't get the concept as he explained

[@mly2883]

So simple and easily explained unlike others.

[@GTayanes]

I thought the degree of freedom only applies to multiople regression or multiple Analysis of Variance.

[@backpackersstudiobd]

Your last line before "thank you" was so awesomely funny and refreshing in this time of Covid-19. Hilariously educational. Thank you.

[@dr.tinega2370]

Such a beautiful piece. Am fully equipped with knowledge now.

[@saeedalzahrani1316]

No one before explain this to me like your video, please we need more about t-test, anova, regression, if possible Thanks 🌷

[@hatebreeder999]

I had done this in college 15 years back, passed the exams & scored well but never really understood. Now I understand it fully. Thanks

[@southerngirl411821]

I would like to say that this by far has made the most sense to me out of many videos. Thank you!

[@y_p7]

finally sombody in this KZbin manusphere made me understand it thank you from the bottom of my heart

[@jeffrylauraedwards]

Thank you. I know it takes a significant amount of time to prepare and illustrate so well.

[@sandeepmandrawadkar9133]

Awesome explanation for both degree of freedom as well as Chi-squared test! Thanks for super simplifying the concept Sir!

[@lorismithokon9028]

Wonderful video. I love when you are explaining a term, you use part of the term in a sentence that it explains it so well. Thank you!

[@teddyw.charawa8989]

You are very simple in your lectures and yet immensely informative. Thank you a million times

[@irenejag6717]

Incredible. Your voice is soothing and so easy to listen to. Thank you.

[@jevjev6755]

Dr. Piers this is the best explanation period! Thank u so much for sharing you knowledge in such a practical and understandable way.

[@omerahmaad]

No one has explained degree of freedom to me before this video. Thank you

[@Troglodyte2021]

that is an elegant introduction to Chi square test! salute!

[@nournote]

Thanks. I learned this test 17 years ago. The teacher back then insisted on the calculus part and not enough on the methodology. This is much better.

[@THE______TRUTH]

Thanks for explaining the 0.05 value and it's significance in more detail. A lot of people just say to get above it and dont explain why.

[@lbboardingb3356]

The Truth dude shouldn't you know that? I mean, you are one, you are all, which of course means you are the chai squared test.

[@bharatbhushan218]

A very good explanation for the Chi-Square test. You helped me a lot by sharing this useful video. Thanks a lot, Sir.

[@JohnMooreVlogs]

This was a great explanation and the best I've seen to far. Very helpful!

[@siddhft3001]

This is the video I've been looking for. Thank you very much for such a good explanation!

[@chandanabasnayake]

Thank you for giving such a wonderful explanation. I tried several other KZbin videos but not understood the topic like this.

[@iwanttobeacat417]

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!

[@lukepaluso9863]

Well made! I appreciate the introduction to the Chi-Squared test. Since I haven't studied this at my university yet, I was looking for a clear and concise introduction. You helped me with this

[@maiguelmoreno9027]

Cheers for the Video! Forgive me for butting in, I would love your thoughts. Have you tried - Zenatthew Planning Paradoxal (search on google)? It is a smashing one off guide for building your Chi energy without the hard work. Ive heard some interesting things about it and my coo-worker got great results with it.

[@sarahfitzpatrick7723]

I never understood why df was n-1 but you explained it perfectly with the chair example, thanks!

[@alicefan8857]

[@therossbennett]

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.

[@pillslifestylereviews6714]

The mars example was awesome, thank you!

[@shifavinchu]

Very good explanation, really cleared the doubt regarding df. Overall 10 of 10 for explanation and presentation
