Brother here is definitely Republican. 😂

I’m a mechanical engineer. Of course we took the appropriate statistics and probability class but never saw the real significance until my 5th year of being an engineer and working at GE healthcare. Now I apply the DMAIC approach as much as needed.

Great video, thanks for the clear explanations!

Isn't this a repeated measures t-test rather than a matched pairs?

Z test for proportions T test for means Chi Squared Goodness of Fit for 1 sample with 1 variable to test if it is different for the population (ie test if the distribution of race is different in 1975 population to the 1980 sample) Chi Squared Independence for 1 sample with 2 variables to test if they are independent (ie test if chess and IQ scores are associated) Chi Squared Homogeneity for 2 samples with 1 variables to see if they have the same distribution (ie to test if men and women have the same distribution of living arrangements) T test for slope

Simple and to the point, I learned more from your video than the 1 hour long lecture my teacher gave 🥹

I learned more in this video than 4 month's of college classes 😂

thank you! now its all clear

the empty set is a subset because a subset can be created by removing elements from a set. So if you remove element by element from a set, creating subset of subsets. then finally you have the empty set which is subset to its set before removing the last element

Thank you very much, you are a genius!!

everyone in the comments are saying that some tests are 'better' to use than others ( t test is better than z test) but i have always thought that each hypothesis test only had 1 test/method that you could use. do some exam questions have multiple tests that can be done on them to get the same result and if so what tests can be used instead of others. thanks

great vid champ

Thank you! You explain this so much better than my professor does.

My statistics professor suggested your video for our assignment. Well done!

Thank you, ill remember... skewness follows the tail

Hi there. I have just found your content, and what I like about it the most is that you focus on a single topic or two as a way to compare and contrast. I am an undergrad and in class, we have to listen to tutors talk and explain a bunch of different topics for two hours or longer. Thanks for sharing. Cheers

Excellent. Cheers

This is the first video that made p-value and alpha value make sense to me. Thank you so much!

mad respect mate !!!!!

👏

abe bkl formula bata na

Why do we consider 0? arent we talking about integers only?

Thank you for saving lives

Woow woow this is the most clear version of understanding which test, when, where and how to use the statistical test. Thank you

way of deliverance is great.THANKYOU SIR

Great video. Thank you.

Thank you so much! I like the way you explained it! So easy to understand’ thank you!

I think proportions are for categorical response or variables and not qualitative as said here, qualitative research itself its so much complicated with thematic or content analysis of codes and quotes, regarding Z and t test I think its about sample size that dictates which one to be used, I stand to be corrected if I am wrong

You mentioned in 4:40 about t-test for one proportion, which DOES NOT exist because Z-tests for proportions are based on approximation of normal (hence, z) to binomial distribution so it's only z-test for proportion. In times like the sample size is so low in testing a single proportion, then some nonparametric test may be used, like the binomial test.

Thanks. This is good theory. Can you give us some examples? i.e. what an r score of two sets of data mean and what an r squared of the same data sets mean? That would be really helpful. Thanks.

Great explanations!

Wow. Great introduction. The context is great. But apart from the context, the teaching style is fabulous. Thank you.

I LOVE YOU

Great example 👏🏻✨️ Thank you for sharing 🌹

he is so enthusiastic about statistics and I am sitting on this side of the screen balling my eyes out because I don't get it but I need to pass this class as a prerequisite.

Thanks, this was incredibly helpful!

tell me please, why am I learning more from KZbin tutorials then from my PROFESSOR???? thank you!!!!!!!!!!!!!!!!!!!!!!

OMG you are amazing.. this was so easy to understand thank you!!

The anguish in thumbnail was basically me before watching this video

Awesome video! Thanks, King!!

Thank you It was really helpful❤

"Some things that make people antidepressed." I can’t listen to someone this ignorant.

You saved my day, thank you so much; wonderfully explained

this is the dumbest concept in all of statistics

Nobody ever explained it this way, thankyou so much. This is the best explanation.

The frequency he's talking about is the headcount and the relative one is the real frequency

Halfwy through the video md still not a good explanation of why he claims the z test "sucks" other than his opinion...

Bro u r awesome thank you so much love from India broo🎉🎉

That was a surprise, the way the presenter was talking and the music at the start made me think I was watching an ad haha.
