Stats: Hypothesis Testing using P-Value Method (Example)

[@tonyd8707]

best video on the web to figure this type of statistical calculation out, hands down. Thank

[@Hercules003]

If P value is HIGH > the null must FLY If P value is LOW < the null must GO Amazing way to remember this.Thanks.

Hi👁👁just felt like replying cause it’s been 7 years😂

[@vidajoymangubat6516]

I really wanted to thank you for your videos! After watching dozens of videos on p value i finally got it!! Thank you so much!

[@Narae-um8jv]

You have the perfect traits for a great teacher. Very organized, thorough, simple. Can't thank you enough

[@texasskittles556]

THANK YOU SO MUCH! One of the very few youtube videos I could find that actually showed how to find the p value using the calculator!

[@praveenkumarvenugopal1847]

Watched 6 vids on Null hypothesis. Only this one made it crystal clear with a good example. Thanks a ton!!

[@daniellesmith4447]

You are significantly better at explaining statistics than "crazy hat dude" on KZbin. Thank you!!!

[@billwindsor4224]

@poysermath excellent presentation, sir; you have constructed a clear, methodical and thorough calculation of the p-value method for hypothesis testing. Best on the web that I have seen. Thank you so much!

[@gooddeedsleadto7499]

One of the best explanation on u KZbin

[@gooddeedsleadto7499]

We reduce the probability of type 1 error using p value method? because with p value based rejection ensures it is far less than even the given significance level, thus avoiding type 1 error? Please verify my understanding. I understand in this example p-value is supporting the belief or Null? Thanks

[@SankalpMalik93]

Great Video. Infact the best I found on KZbin. Just clear that thing "null must fly away", it seems as if u are going to reject it....

[@Anethereal]

Yiu just saved my whole semester..thank you

[@mylannelson1759]

How can I find down this p value without the calculator? Thanks

[@junny4k]

Mylan Nelson put ur test statistic in the z table

[@NitishRaj]

What if my test statistics computed using chi square and it is left tail test. Do we say if P

[@EatOneWorm]

Well done, I feel much more confident in this. Should do a video about the differences of sample sizes and how it effects the distribution as well as the ways of finding sigma. Thanks.

[@Жанна-л7р]

oh my God i finally understood what does p-value mean! THANK YOU so much!)))

[@idiotrun1997]

Thanks for uploading! Clear and concise explanation. This really saved my ass!

[@teenashamsaei3720]

This guy is an awesome teacher

[@KgosiDube]

Better than Khan Academy and lectures combined! LOL xxx

[@drwagumaeliasjb4643]

can you demostrate using the table?

[@EnvisageKenya]

If the video is > that the rest on KZbin, the LIKE must fly!

[@sadiya9865]

Thankyou!!!! This is really good

[@Nosisalinda]

Thank you Sir, all your videos are helpful.

[@elvisboyaci8276]

when you say null must fly it's confusing cause it's sounds like "null must fly away" i thought we gonna reject it. I think you need much clear slogan for it imo.

[@MaNaicZ]

high = greater than... I think it works imo!

[@gravekitty]

What if x-bar isn't given in the problem?

[@walidzein1]

Then good luck

[@Doomwyte]

Thanks for saving my mark! xD

[@fabianrichburgh6517]

you deserve an award!!

[@sadie1837]

great video. I learned a lot. Thank you very much.

[@apoorvadk9635]

Thank you so very much, Sir!

[@THEMW3FANBOY12]

Do you double or half p value for a two tail test

[@gladyslopez7984]

googlemail You multiply the p value when its a two tail test. But when graphing the p value, you use half of the p value.

[@zionwilliams861]

Double

[@joannawoodard2511]

Amazing!!!!

[@rishabhkumar6535]

awesome explantion

[@gladyslopez7984]

Thanks for sharing!!! :)

[@islamians1]

best video

[@Semnyawenda]

thank you sir! you saved my butt!

[@chaitanyasawhney1658]

Great

[@jolorianilingan1527]

Thank you so much :)

[@shinchiwarrior]

excellent! thanks! helps a lot! Let fly the NULL !!

[@valentinafrench9639]

thank you!!

[@mbongenimadi8162]

but with this problem you can argue and say the claim is from the battery producers that the mean battery life is 30 hours

[@retry4581]

amazing.
