I've been seeking out your content since my freshman year in college. Thanks for teaching me calc, stats, chemistry, bio etc. I know all my courses have a video of yours to explain all the info I need. Thank you for the constant help

[@kaitlynpowell5294]

Thank you so much for this video. I'm taking statistics right now. I'm a graduate student. This was super helpful. Online learning during this pandemic is not easy. Thank you!

[@razabazal4669]

i hope you are getting paid more than my three professors combined.

[@factsgood88925]

[@amanjeetkumar2362]

Try statistics for business and economics by Anderson and Sweeney

[@Marie_CT]

The wrong people are in college classrooms I can tell you that much, not all of them, but many professors are knowledgeable without the ability to teach. I hate it.

[@prudenceantonio3494]

Thank you for this video . M having an exam tomorow

[@meownyaaaa1441]

I LOVE YOU ORGANIC CHEMISTRY TUTOR

[@minaben7003]

Thank you so much ❤❤❤

[@adwoamarfowaa5672]

Please I love your videos. Can you make videos on ANOVA ASAP?

[@jab376]

Adwoa...Are you ordering pizza? Shame on you for the command. This guy's is not getting paid...douche bag

[@quingquing]

Thanks for this great video Organic Chem Tutor. The best comment Ive read below is :"I hope you are getting paid more than my three professors combined". I would have commented the same!. by the way may I know what program you are using to make the video?

[@dailyworddigest4229]

HI, you are an awesome teacher. Please how did you arrive at 0.95 FOR THE DO NOT REJECT REGION ON THE GRAPH. I hope to hear from you soon. thanks

[@choolwesimafuta9361]

That's a probability distribution graph... The area bounded by it is 1 so because alpha is the area of the reject region which is 0.05. It follows that A(rr)+A(nrr)=1, A(nrr)=1-A(rr)=1-0.05=0.95

[@vishnuvarma7693]

that was an epic informatibe video regarding the topic man u earned a subscriber today Ciao

[@vicadabramvincentm.8139]

THANKS FOR THIS LOVE Y'ALL

[@Makleech]

[@rem6581]

this really helped thanks

Yes they have a case of senioritis😂

[@Maharrami]

Great job!

[@AI-kr7mj]

I am confused on Null and alternative hypothesis? Will anyone help me to shutdown this confusion?

[@dianabarbara2948]

Null hypothesis for chi square test always states that the two variables are independent from one another

[@constructionworld9137]

Best tutor 🤓Give a like

[@bloodmachine3787]

Can anyone explain why it was a right tail test?

[@Onshooda]

Great job 👌

[@theodoresweger4948]

Thanks well done...

[@evenastyles3008]

This is great!

[@misturahayoola259]

I dont understand why the null hypothesis is independent and the alternative is dependent can someone explain it to me please 🙏🏿

[@syamilmuhsin7]

Isnt the number of average hours of DEPENDENT on types of students supposed to be the Ho?

[@gideon9780]

Thanks a lot

[@nayzethperez2524]

How do you solve for expected frequency?

[@arpitchaudhary7274]

thanks a lot!

[@fahyen6557]

Good video

[@baddevildn528]

thank you 😍😍😍😍😍😍😍😍😍😍

[@nokokgomo__lazzy]

ANOVA... Sir ,I bet you'll explain it better

[@ObeyGoodness_20]

U are just too much as a genius...

[@danishcode]

How can we came to know it will be right tail test or left tail test??

[@dianabarbara2948]

Always right tail here, the idea is that the bigger the chi square the further away you are from the expected values if the null hypothesis is true! So the bigger the chi square, the more certain you are that the variables are not independent

south australia western australian can i have houseing agrement and my tractor and trialer linceene and car licnene back im not eplict im fine

[@mathalysisworld]

You did not even tell us why you multiplied row and column and divided by total to find expected value.

[@eggsammich1186]

(row total)(column total)/ grand total is the formula for expected value

I swear to god, this man is a legend. Thank you so much!

[@TheGhost-lm1xp]

I am a medical student and we started to take the statistics in the third year , but our doctors are so damn bad in it , they don’t explain anything and we left confused all the time , I will have my final exam tomorrow , the idea is frightening. But I am one of the best students in this subject in the stage lol but that fair can’t get away unfortunately....

[@sumandeeptoor3216]

I would have failed all my math and stat classes without your help. I can not thank you enough 🙏

[@josephagu5958]

Cool

[@susannacristhappa5204]

I finally understand this!! yayyy thank you!

[@mikayyy7731]

Is the alpha always given?

[@explorer0082]

Why is it right tail critical region ?

[@bradleyjones2429]

Lol learned this in stats 2 weeks ago🧇

[@Joooshey]

Can you please do effect size?

[@FluencyAccentCoach]

Thank you for teaching.

[@tieutuyendang4545]

Thank you so much. Your videos are really very helpful for my stats classes. By watching your video, I achieved my last semester successfully and I keep watching your videos for my next semesters ahead. I wish you all the best to your life and your career. Again Thank you so so much!

[@haftomhagos7122]

Thank you so much

[@richardmanu1850]

thumbs upppppp

[@solz006]

thank you

[@jesical94]

Which program do you apply to make the videos guys?

[@jesical94]

Waiting the answer 🥺

[@tomatrix7525]

I don’t know. As far as I know nobody knows. This is a question I see commonly, with no reply. He has a big taskbar around the area but he cuts that out of frame.

[@DogeFrom2014]

Probably the same program that Sal Khan uses. I forgot the name, but you could look it up.
