Oh my goodness! Is this what my teacher has been trying to say for the last 3 sessions. You clarified it for me in less than 10 minutes. I appreciate your ministry. Gracias! It finally makes sense.

[@PradeepKumar-rx6li]

By far the best explanation compared to other recent videos i saw. Thank you.

[@MrSupernova111]

Awesome video for beginners! It finally occurred to me why some programs like Excel don't produce CV in their output as the p-value leads to the same conclusion.

[@fairuzhamizah5383]

Well-explained! Thank you, you've just earned yourself a subscriber.

[@gholimoli7072]

One hundred times thank you for simply perfect explanation

[@damiananslik6214]

This channel is amazing. Great teacher, good pace.

[@Sundardevsaha-e3k]

Very thankful to you for this description. You're helping me understand how to conduct my research for my master's thesis. :)

[@wonger5]

This video explained the topic in 13 minutes better than my college professor could in an hour and a half... Keep up the good work!!!!

[@meditationclub267]

outstanding explanation... I've been searching so long for this type of lecture..... kudos to you....

[@tamargrey8529]

Had to watch 5 videos before this until you finally explained what the critical value actually means and how it relates to the curve. It seems a lot of people leave out what I see as the least intuitive part. Thanks.

[@8siandude72]

10/10, better teacher than my university lecturer.

[@shineshine9599]

very true...

[@snegugungcece5424]

so true

[@petemurphy7164]

This is very true (rather unfortunately though, I pay an awful lot for my university classes, ultimately I end up coming to TH-cam to really learn the topics.). Thanks 'Math Meeting' for making this video!

This video is be far better than any I've every seen on Chi Square. I noticed how your made a good relationship with probability. Could you please make some more videos on Sampling distribution, Empirical sampling, Bayesian statistics. Thanks

[@shopn0bilashi]

I am from Ethiopia, It is too helpful .thank you very much.

[@lamalamalex]

great video! I needed a refresher. However I highly discourage saying "accepting". since it implies the alternative we proposed is true but there may be other alternative hypotheses.

[@fizzjuty5798]

what would you recommend saying instead?

How did you come up with the 0.1 for the rejection region?

[@Sisenor522]

Hi I just had a query that my proffessors told us to always asume cv to be 3.84 for a 2*2 table. How should I assume what's the alpha value is ?

[@chrisdude942]

How do you decide upon the rejection region and it what is appropriate?

[@mosesmuchemi7221]

what if those observations represented observed accidents occurring in 6 factories. how would you frame the null hypothesis?

[@royakhoii1988]

Very useful.

[@xPandaKiller]

How do you decide your level of significance (shaded area in the graph)?

[@millymcbug]

My teacher says that if it's not given in the problem, one can always assume a 0.05 level of significance.

[@edwindsouza7157]

Could I ask you a question? I coudn't define the rational of ratio of data which one ratio for ex: (1.1.1.1.1....), 9.3.3.3.1) and so on. Some of these we have to know clearly when calculated this.

[@generalmanageroperations6387]

well explained

[@tylerbonts]

The absolute best Chi Square test video.

[@ronseymour4976]

I don't know much about statistical methods but I am a mathematician. Your presentation was very clear even though I came to this topic with no prior knowledge.

[@kristenchantelle3404]

Hey, I know school is back and fall classes are here with us meaning the essays statistical units and assignments are back. I could be of your assistance in handling the papers and I guarantee you value for your money with an A+ results. Kindly reach out to me through my email address [e-mail]

[@samiranroy4188]

Thank you for nice explanation, i have below questions:
1. why this curve is little bit different from normal distribution
2. is there any two-tail chi Square test, because, alternate hyp is not equal, so do we consider it as two tail chi square test like t-test etc.
3. why we do chi square test but not t-test, is there any reason to do so, in t-test we also do statistically difference between two (paired or unpaired) sample?

[@Technicolor-mother]

I am plugging the DF of 5 with an alpha of .01 into my applet and I am getting 15.5 consistently... Why the error do you think?

[@tejassr1357]

How to obtain that curve? What are x and y axes?

[@salvadorrivera1884]

Question: Mr. Math Meeting said that the null hypothesis is what is currently believed to be true, the man suspects a casino of using unfair dice, so wouldn't what is currently believed to be true be that the dice are unfair. Making the null hypothesis to be die is unfair. Therefor we rejected the null hypothesis and accepted the alternative hypothesis, which is the opposite of the null hypothesis, the die is fair. But Mr. Math Meeting said the dice are unfair, so which is it?

[@abigailmachaka3090]

You are not guilty until you are proven guilty. So the basic assumption is that our dies is fair..That's our null hypothesis

[@harishscholar]

where did you use degrees of freedom?

[@oibal60]

Thanks.

[@nchecker00]

I didn't get. why should we divide (o-E)^2 by expected value in Sum to get X^2 distributed random var, if X^2 is the Sum of N(0,1) distributed r v? if so why do not we divide it by variance instead?
