01 - Hypothesis Testing For Means & Large Samples, Part 1

[@shiromijayawardana3164]

He is an amazing teacher. He makes it so simple and easy to understand and leaves the JARGON outside the door. I managed a B in my elementary stat class because of him. I was lost in my stat class because of Covid-19 all classes went online, and there was no way I could understand probability by reading a book. I stumbled on these videos and decided to purchase a 1 month package $ 20 and it was FULLY worth it. Thank you.

[@muneerak1340]

Wow...what a class! I want his full classes about sampling distribution...where I get it from?

[@muneerak1340]

Can u guyz plz help me?

[@chuckstarwar7890]

I am 95% confident that your statistics class covered at least 95% requirements for quality control of business operations (manufacturing, financial, legal and risk management). --- you are a great teacher.

[@kokanee22ify]

Seriously, I just want to say thank you for making these videos. I have been trying to learn stats through distance learning textbooks and you've saved me.

[@IndrajeetSEO]

Niki Hand yeah!! he really saved my paper..

[@aminualiyu3773]

thanks alots we really appreciate...

[@hamisimwinyi297]

It's very good lecture but it would be much better if you put the series of all lectures because we face a lot of difficulty in finding them

[@Bachiego]

was he able to post the series cos i am still looking for the series on hypothesis testing

[@rayan4928]

The link below is an example of his lecture series, free, and in order. You may check the main of his website as well. www.mathtutordvd.com/public/Mastering-Statistics-Video-Course-Vol-5-Hypothesis-Testing-Part-2.cfm

[@phoenixrising.9741]

thank you

[@bazeerali123]

@@rayan4928 many thanks...

[@zhuwenhao4852]

exactly!

[@maxresdefault3691]

How to find the previous lessons? Please organize it all.

[@sahilmohammad4336]

Almost all distributions convert into a normal distribution as n ( number of samples) is very large (its better to say n -> infinity) . This is the essence of the Central Limit Theorem.

[@sudharshanchakrapani7111]

Amazing explanation. I am able to understand and follow the explanation in-spite of being a below average student. Thank you so very much for making theses videos.

[@susannamuganyi8678]

I came across your video looking for refresher on hypothesis testing and was pleased with the simplicity with which you explained the concept. Very easy to easy to understand. Thank you!

[@dannyassuncion8714]

Very nice explanation.... how about this. In a class at the University of Florida, 49 students are given a blind taste test comparing Coke and Pepsi. Approximately half of the subjects are randomly chosen to receive Coke first and the rest randomly receive Pepsi first. Why? Coke was preferred 29 times. 1. Is there evidence to suggest that students have a taste preference between Coke or Pepsi? Carry out a hypothesis test by completing the following steps, and using a level of significance of 0.05: (a) State the null and alternative hypotheses (b) Calculate the test statistic (c) Calculate the p-value (d) State the conclusion

[@whitefang6062]

If this guy were a stats lecturer in my university, every student would pass.

[@keithndlovu44]

PLEASE MAKE A PLAYLISTS MAN!!!!!!!!!!!!!!!

[@giftukochovwera3725]

[@carolsamm8485]

Thank you very much! You have managed to facilitate my learning because my books of statistics have actually confused me.

[@abebawdebie5751]

Thanks from Ethiopia

[@iicoleworld548]

for a 1 tail test, at 0.90 confidence level, shouldn't your degree of freedom be 1.645 instead of 1.28?

[@nowshadkhan670]

THANK YOU SIR LOTS OF LOVE FOR YOU FROM BANGLADESH !

[@kaykun01]

Great lecture but please put a link of the previous video and the next video in the description so we can follow them in order. i cant find the the previous video you are referring to in this

[@Joe_Fauci]

Your statistical tutoring videos are incredibly helpful! Your clear explanations and easy-to-follow examples have helped me grasp concepts that I struggled with in the past. Thank you for sharing your knowledge and expertise!

[@lauraalmaguer6429]

Hi thank you so much!! I understand you made these a long time ago but if you happen to read this, my problem is understanding when to use the formulas and I need a list of the formulas to use when these problems come up. Is there somewhere I can get all of these formulas and rules Thanks

[@kamemugg1280]

I don't understand where you are getting these numbers.

[@widdalightsout]

Sir you are amazing, thankyou so much for making these videos they are helping a lot.

[@Shnauzzy]

[@tripurarikumar645]

Sir how I can get all the lectures of statistics given by you?

[@lolitailumin167]

Where did you get the value of one tailed and 2 tailed test?

[@curdyco]

Where did this formula at 3:45 came from?

[@pasanglhamusherpa3592]

Thank you sir. You saved my time.

[@marienoel7672]

Thank you soooo soooo muchhh😭💯🙏❤... God bless you

[@dunnigold]

[@awilmohamoud2721]

Allah is the Light of the heavens and the earth. The parable of His Light is as a niche and within it a lamp: the lamp is in a glass, the glass as it were a star Durriyyun, lit from a blessed tree, an olive, neither of the east nor of the west, whose oil would almost glow forth, though no fire touched it. The exact translation of the saying is, “I bear witness that there is no deity but Allah, and I bear witness that Muhammad is the messenger of Allah.

[@aminualiyu3773]

thanks alots sir we really appreciate ur effort...

[@brandomiranda6703]

What I wanted to see when N=100,000 and the p values are tiny. Ie the power approaches 1

[@cks7298]

I don't understand you find the number where the one tail test from?

[@Usas12fann]

Kosal Chin These values come from tables. Search: 'Standard normal table' on google and you'll find it.

[@venuspalting4752]

Thank you very much sir.

[@tbrowntracyj]

LOVE THIS GUY

[@harwinmanickavasagam1580]

Can i know how you get the value for both tail test.Because u just straight away write out the values without showing where u refer to get those values.Please give an appropriate reference to find out how u get those values.

[@felipeortiz191]

HARWIN MANICKAVASAGAM u look then up on a T table, it can be found on your stats book or google images

[@jamaicansistarobinson7587]

God bless you!

[@cmu1919]

[@lilyafauza1966]

How do you get 1.28 for one tail ?

[@gihanize]

you got to find it from z table

[@huayeli408]

the z formula is not correct, should be sigma, not s

[@slwankaedbey775]

The biggest problem is that they are not free ... what a waste

[@abdallahraafat432]

Why the H didn't KZbin recommend me this earlier?

[@paitienceseraphine6928]

Find it for yourself, KZbin don't have to recommend this video to you.

[@aabbcc112233ooooo]

These videos are just sample or teasers. When it comes to to the real videos they have been cut short to make you go to the paid site.It is extremely unfortunate. I'm sure the guys must be deriving some kind of sadistic pleasure with so many people showing interest
