I love how you took 2-3 minutes to explain WHY are we testing. many people forget the why and jump into how immediately. thank you.
I just had a 2 hours long lecture on hypothesis testing as part of my MSc but that lecture has not given me as much as this 14min video has helped to simplify the fundamental understanding behind it. Great job bro. You are a role model for me. Want to become like you one day.
I am currently learning statistics in my college but I gained a lot more knowledge by watching this video compared to my whole syllabus.
Great work sir 👏
Teachers like you are real blessing
Thank you! The series was super useful! I would love to see a video on various types of tests (z, t, annova, chi-square). Thanks.
This is the best video so far to me about hypothesis testing, you have gained my respect with your explanation skill, keep doing it, all the best.
OMG how can I miss ur videos.....u brilliant teacher ...can't describe ur teaching it's totally amazing,I spent 2 hr in Google read lot of website content but couldn't unstd..18 mint more effective in my life...
You are simply sooperr...Before looking this video..I had gone thru theory..but I didn't got nothing..But after seeing your video..I got clear cut idea about HYPOTHESIS TESTING.. REALLY I admire ur way of analysis thru simple anologies..
Thank you so much 🙏🙏🙏
Sir, please make a series of all hypothesis test techniques, When and How to use these techniques with practical examples?
Absolutely great video :) got the entire concept.
Great video!!! That intuition of how nature works was awesome. Also, got to know that "rejection" is a confirmatory test, so they try to reject the other to justify their claim which indicates that "assertion" is considered non-confirmatory in proving a claim!
This was super useful, one of the best!! with lots of examples...thankk you so very much!!! You are amazing!
With just one video, you taught me more than I learned in my marketing research classes. Thanks bhai
👍😊
Sir, your way of explaining this things is outstanding, please do cover other topics as well it might be more helpful.
I just see best video on hypothesis testing. thank you, sir.
sir your way of explaining things make it simple to understand the logic behind it
You really are the best teacher there is!
More power to you, keep up the good work.
Thank you Dhaval Sir!!! maza padi gai!!!!
Your videos always motivate and give better ideas, thank you sir🙏👍
excellent presentation. really helpful. thank you.
Your example to teach concept are amazing I really like this
Listened to N no of lectures on Hypothesis Testing, the more I watched, the more it got confusing, and it didn't help me. But Let me tell you, this is the best video so far and I am glad that I came across this video(or else I would have been clueless for a good amount of time I guess :P) All the examples that you used definitely made a difference. Thanks for making it digestable and thanks for uploading these videos in the first place. Amazing work!!
Very impressive, Thankyou Sir
Your way of teaching is excellent!!! Sir. Thank you for the video
It was a really amazing...simple...clr and awesome session. the greater complications made simple💯 thanks a lot sir! for theses simple videos... also they are more effective! thanks a lot.
I have been watching your videos. It is amazing. I used to watch statquest with josh. But you also gave me an additional insights about the hypothesis test…thanks … Jsk!!!
The examples were really good and easy to understand the concept
You are making students life easy
Thank you bhai
Thank you sir for this lecture, I get clear in concepts
Thank you for explaining it in easiest way
Thank you, everyone talked about calculation and not the concept deeply,❤
Thank you so much, I understand this concept from you❤
You are doing absolutely Great Work, sir.
Thanks
Thanks a lot! Some times all you need is someone to explain things like you are five.
Also Aryabhatta rejected the null hypothesis much before than Copernicus.
your way of teaching is awesome even colleges class which student is paying 1.25lakh per semester
Thanks for the explanation Sir. I have understood very well what hypothesis is!
great explanation! Thanks
You made my day clear with this hypothesis, thanks 🙏
Glad it helped
Awesome understand in one look
Amazing explanation ..
thank you sir for such a great video .please bring a video on all test ie z test ,annova ect.
Thanks a lot, and that marvel poster in background seems like awesome !
Sir you are a great teacher!
You are really Amazing!!
thanks for the video, its been 3 days since i am trying to understands this concept
excellent explaination
can you please make videos on all the techniques, z-test, t-test , anova and chi-square test, that will be very helpful...
Yes I will
@@codebasics thankyou sou much
@@codebasics good to hear that. Can't wait long for that :-)
@@codebasics We are waiting!
Simply wanna know when we can use z test t-test chi square anova
Hi Sir, Really great explanation and super useful, hope more videos like this to come from you
Excellent explanation. From that video, I think we can sum up the point that; Hypothesis testing is to reject the "established statement (H0)" in order to prove the "New Statement (Ha)". Where the H0 statement is opposite to the New Statement.
Nice Explanation
Very useful information thanks for you time and knowledge sharing
PERFECT SIR🙏
Could you please make videos on t, annova, chi-square test?
Best Explanation
Thank you so much sir
This your explanation is simplistic and awesome
Glad you liked it
Please upload more videos in math and stats playlist. It ll be much helpful
Hi Sir i am a big fan of your teaching and has learnt of concepts from your videos inspite being non coder background..sir i have a question " whenever Sachin scores 100 India looses" ..how to reject this hypothesis using data.. could you please make a video on the same.
There are a lot channels explaining hypothesis testing but none explained the Ho and Ha as lucidly as you have done.......
can you give the more video about hypothesis testing ,for example : individual videos for Z test, T test, Anova test, Chi - square test
Please provide further explanation on methods of hypothesis testing
Can You Create a Video based on how to implemention of hypothesis Testing using Python .
I'm Very Eager To Learn From You Sir , Also I saving my money to purchase your Courses in DA.
And Very Thankfull for Guide us in perfect roadmap with your high Knowledge.
💫👏👏👏
Very good Explanation brother...Keep up..
Glad it was helpful!
Waiting for this
You are good. Lemme sum up here what I have learned from this video:
There is an established fact. Like say 'animals need to eat in order to survive'. But one day a crazy scientist came up with 'animals don't need food in order to survive'. So, in terms of statistics, we need to prove it. We can perform hypothesis testing here. In order to establish the new theory all we need to void out the established one and old one will be automatically replaced by the new one. So, what need to do? We need to nullify the already established one that 'animals need food to survive'. This is the one we are nullifying and this is the reason we call it null hypothesis. And alternate hypothesis is the second one that came as the alternate of already established one, 'animals don't need food to survive'. We nullify the already established one why it is called null hypothesis in order to establish new (alternate) one.
TLDR, we need to drag down the top one (or nullify it) in order to put the second one (alternate) to the top. We don't need to put effort on second one to be better to reach the top position, all we need to do is spoil the top one that second one automatically will hold top position. That's all about hypothesis testing. It's a cruel world.
Thank you
WOW your videos super cool and simple to understand
Glad you like them!
Thanku bhaiya
Sooooooo prrfect❤️❤️❤️
Thank you for this much sources please continue this playlist. lob:)
Thank you, I will
thank you sir
superb
Hey codebasics, love the videos but there is one fallacy with your point about randomness. True randomness actually doesn't exist and let me explain why. "Nature tricks you" is not a valid answer to why there is an underlying reason to why outcomes occur.
The true reason is that you are human with limited capabilities and understanding of how everything around you works considering you did not create everything around you. To the human, it can be perceived as randomness, but in all actuality, all outcomes have a reason to why they occur.
In one example, if you were to flip the coin and it lands on heads 5 times in a row, there are a multitude of factors as to why that could occur. Depending on whether the coin was on tails or heads in the beginning, depending on the force and strength exerted when flipping the coin, the height of the coin before it was flipped, etc.
If you were to ask a physicist how a bowling ball transfers force through bowling pins, they would be able to get exact calculations to understand why the bowling ball affected the pins and led them to result in their location after the force. With these calculations if the exact amount of force was applied from the bowling ball to the pins you would be able to replicate the result perfectly each time through the math. However, if you were to ask a human who is unaware of the laws of physics to them the result of the bowling pins after the impact of the bowling ball certainly would be quite random.
I disagree with you in that "this is the natural law" that things happen randomly and you have no other explanation as to why it seems quite illogical and I am honestly quite surprised, with that logic, it would be pretty impossible that all of us even exist if things were based on randomness because the way our bodies even work is quite sophisticated and all of the internal properties work quite seamlessly 24/7 without our control. Scientifically everything has a measurement and specific pattern, just because we don't understand or have the capability to compute all laws, measurements, and patterns, it doesn't mean that it is random and because nature tricks you. If anything, this should allow us to push and understand more rather than stopping at that.
Hope this makes sense,
Enjoyed! this I agree :)
but then quantum physics appeared and we were lost once again...
Bruh you just rejected his null hypothesis
Interesting!!
Pleas make videos on calculus basic math for data science
Does anyone know how to tell if your dealing with nominal scale data or interval scale data when your x axis is nominal scale and your y axis is interval? For example, if you have a graph showing the exam scores of male versus females (nominal scale) and the scores were out of 100 (interval), how do you decide if your graph is nominal or interval scale?
Now i am very much clear about hypothesis testing after ur videos.many thanks
So I am new to Machine learning and this field I am physics students and thinking that machine learning is more coding but Now it seems like machine learning is more like mathematics and statistic am I right plz clear my confusion I would like to choose which one is best fit me Data analytics or Data Sciences can't thank you enough you for your videos which make me most helpful to clear my vision for my career change thanks a lot thanks
good video
Can you make python videos on hypothesis testing
Well explained
Glad you liked it
finally :D
if you did it early i could answer the ques in my interview xDDDD
We want full sylebus statistic for data science tutorial.
Where’s the next video? Can you make a video about all the tests and when we apply them
Can you pls tell me which processor is required for machine learning for 4years of my college
i5 or i7
i7 will be better
I am taking a $2,100 per month boot camp. And they are using your videos to teach data structures and algorithm🤣🤣🤣🤣
ahh... which bootcamp is that? Can you give me their website or some link where I can see my videos?
@@codebasics bhai kuch tho gadbad chalraha hai ....
@@codebasics data engineering track springboard
Springboard
You've been scammed
Oh my Gujarati brother, nice to see your accent there. Also it's "Copernicus" 😂😂
u know....u r a superman
Please explain woth some example so that cam understand better.
I had finished my degree in bsc statistics (graduate).is masters degree compulsory to become a data scientist?or can I learn data science skills now while doing any job
masters degree not required my friend. You can learn everything on your own
It mean that prove that some fact or law is wrong then use hypothesis.
Bro, Urdu Mn Video b bna dia krin ....mne phele b Apse Request Ki thi.
Bhai meri hindi channel hai uspe mai hindi me bhi video upload karta hu. please check that. This particular video I need to post process so it will take few days but eventually all my english video will be available on hindi channel.
statquest vibes?
bro where is Nadal ??
Guys, why trade if you can invest in Flirt Invest or stake your own coins?
Im from philippines. Im incoming 1st year college at BSIT course.. I really want to learn in advance.. Please help me im new subscriber tnx
First, read about cool projects such as Flirt Invest and then tell tales about growth
Guys, can anyone explain to me the meaning of holding coins if there is staсking or platforms like Flirt Invest?
it should be revolve instead of rotate😅😅
