05 - Using P-Values in Hypothesis Testing (Compare P Value to Level of Significance) 

Have you stopped making videos? Please continue spreading knowledge. Y'all have the best teachers whom we all need

After wasting much time reading from books and university lecture slides, this is the BEST explanation I have found on why we use p-values. You are a brilliant teacher. There are teachers and there are teachers like you. All the best and thank you very much!

This dude is the Messiah of Math. This dude single handedly is about to save me from my stats final.

you are a life saver. my stats teacher never taught us conclusions for the P test, and I would’ve gotten so many wrong on the test if it wasnt for this video

Love how you repeat everything.

Honesty, I've been struggling to understand the concept of p-values when I took my research paper during the 12th grade. I read a pile of research papers published online and have indeed encountered this esoteric idea about confirming the rejection of null hypothesis using the p-value computed. ONLY, Only when I watched on this video when I finally understood what this idea tries to imply. It took me a lot of days and months and even years figuring this out on my own, since this wasn't discussed really "in depth" during my senior high school years, and it's a total loss for me as a current college student. But now, finally, I am grateful that I have finally understood what, why, and how to compute p-values. I could now relates what certified researchers try to say in their papers published online. Kudos to this great teacher or statistician (I suppose) who made this abstract concept get discussed in a demystified manner a typical freshman student can easily comprehend in less than an hour. Thank you so much, and this means a lot to me, seriously.😊

This man is just wow! You explain every bits and pieces of the topic. Anyone can understand. I recommend all your videos infact channels to people who want to be mastery in maths. Excellent job done.

I can't really express in words how your lessons have made us understand the statistical concepts & theories in a more simple yet the perfect way, Thank you very much (I wish I had lecturers like you during my college days)

I hardly comment , but after struggling for so long trying to understand hypothesis testing. I'm glad someone introduced me to you . The least I can do is comment . Remarkable progress in my understanding

I can't believe how much your words are understandable and simplify complicated topics!

This man knows exactly what students are struggling. Thank you.

You are an amazing teacher, I am overwhelmed and really thank you for such an ostentatious contribution to Education. The way you have explained have made things really visually understandable.My utmost respect for you please.

Thank You Sir! Your explanation is so clear and easy to understand. I got to say that you are just gifted in explaining things in exaclty they supposed to be explained.

The best explanation ever after watching so many videos and articles. Thank you!!

It was a question always that how we can find the actual level of confidence in the real manufacturing, here I found my answer, very nice and clear . Thanks

The candy-examples are awesome. He really explains why(!) you actually need p-values, and he does it in a way so that it really sinks in. Fantastic, just fantastic.

It's kinda worrying that i couldn't understand my professor nor other youtubers in my native language but totally get what you've just explained. Thank you very much.

I cant thank you enough for explaining the intuitive meaning. Because if I cant get the intuitive feeling then it is difficult for me to do the problem and no where i found such an apt explaination. I am feeling quite confident now about the p-values. Thank you soooo much.

wow! it was a revelation! i was struggling to understand the alpha for quite a time - now i get it! you can go backwards for it and make a conclusion about the level of confidence

Thanks a ton sir, I was having immense difficulty in understanding this but your series of videos have made it crystal clear.

Very well simplified. My go to youtube teacher everytime I have a question on statistics. Pleasing continue bursting this myth that statistics is difficult.

This lecture is just like a very interesting movie, most of the thing I started filming in my mind, thank you so much.Teacher, Respect from an Indian

It is really very simple and clear lecture and made the main problem in my mind the p-value went away. Thanks a lot.

Best regard from Guatemala, I love this explanation.

Your videos have offered a lot of clarity to me, thank you!

Wonderfully explained. Really Appreciate it. FYI, I am learning the basics of Stats for Machine Learning and am sure this knowledge (intuition) i got from your views would come to my rescue, when I get the (Aspiring) Data Scientist Job. My Gratitude, Guru Ji.

Very well explained. I had these concepts misunderstood since I was in the university and now I need them for my job. Congratulations

Amazing video - Finally understood the concept of p - values. p - values is area. [ Understood that clearly from this video ] Null Hypothesis is based on which probability has more areas and we reject or fail to reject the statement based on the area of the probability.

After seeing this video.. now it's very crystal clear, which is not possible by reading just books. Thanks a lot.

Yes! You are absolutely right. Teachers and books can be frustrating sometimes. But you made it so easy to understand. Thanks!!!

I usually don't write comments. but this video really deserved it. "EXTREMELY HELPFUL". Thank you :)

Your lectures are very good

...I have a 99% confidence level this is one of the best confidence-level / P-value videos on RU-vid...

Best explanation so far...it cleared my burden of doubt that I was carrying from quite a long time now.

This is an incredible explanation. I understood it in first go after spending a lot of time searching for the right video. Thank you :)

SO SO SO helpful for some last minute help in my biostatistics class... better than my professor

Just want to say a big thank you to you sir for helping me out for my statistics classes.

Apart from what you teach, which is AWESOME of course, personally, I really like your personality I guess, and your energy of teaching. I think you like teaching, and to be it is obvious. At least it is for about 12 years that you are teaching, and of course I do respect to you very much. Thank you very much for everything Sir, you are amazing. Wish the best for you Arman

My experience in making hypothesis: A statistics book published in 1965 had really been my best experience as it simplifies both null and alternative hypothesis. Ho: Most unlikely to find/occur, etc Ha: What researchers need to achieve at the end of their research. The other is what also "practical significance" mean to statistical significance.

You're the best instructor because my problem already solved

The whole series was awesome, best teaching i ever had seen. thank you

Your teaching is awesome...I was scared of this topic...You made it soo clear....Thank you so much sir

Great explanation. The P value was always there in front of my eyes. Thank you for your master explanation.

Thank you for your in a clear and understandable presentation.

2:23 to 12:20 helped me so much, thanks a bunch!

You teach well !! Great job on the entire series

Please create an app where we will find all of your videos Otherwise you are an awesome tutor , teacher , professor .

You are a very talented teacher

A deep and heartfelt thank you for this!

Best video on the internet. Thanks professor.

SO simple and to the point

Awesome awesome awesome!! I have been stuck on this concept of pvalue since 3 days now and so much frustrated...watched couple of videos read so many articles...but I'm so grateful to you and this video that it made me understand the concept pretty well...thanks a lot :)

You are great teacher, very well explained. Thank you so much for sharing.

You are a great man. Really, no body explain this. Thank you so much.

Thank you!! Your explanation really helped me a lot!

Very lucid explanation. Deserves a big thanks.

Awesome, Sir you r best, and I say it with 99% level of significance.

OMG, finally I understood what the p-value is talking about.

w teacher. also it's kinda crazy that we set alpha after to make real world decisions. I see now how statistics can be used as a weapon.

This is one of the best explanations on hypothesis testing and P values. Great work!

Thank you for sharing your knowledge and expertise. Really appreciated.

Excellent, really appreciate the way you lectured its Cristal clear....

Another question: Unlike in theoretical hypothesis, most papers try to set numerous hypothesis by specifying to study objectives. Is it possible to have more than two hypotheses? I don't agree for this to occur.

Well understood

I just wanna say thank you 🙏🏽

Thank you very much for this video. Found it very helpful in understanding how to use the p-values

Thank you sooooooo much for clearing this for me

Isn't it considered bad practice to choose the level of significance AFTER collecting and analyzing the data?

fantastic presentation !!

Hello, great article but i have a question. All the claims that we proving about the population is based just on the sample because z, t, p values are all coming from our sample. What if our sample is biased and not represents the actual population. In this case our z,t p values will be extreme and wont represent the real population. In that case how we can we be 95% or 99% confident to reject null hypothesis?

This man has been really helpful Thank You

Thanks for the great job done. I like all your videos. Am fortunate to have landed on them.

You are just awesome, thanks and respect for you.

Sir, tusi GREAT ho :) Awesome explanation ...the best :)

beautifully explained

you tutorial is awesome sir , but i have a doubt you calculate the p value from the zscore but without fixing the level of significane what are you going to compare the p value with which value of alpha , if my understanding goes right you need to fix the level of significance first and then see if p value is less than alpha to reject null hypo , please clarify on this

Illuminating!

Best tutor thank you sir

Hi! Can you explain something to me. If we don't specify significance level ahead of time isn't that ''p-hacking''?

Thank you so much professor

Grand salute this man

You are the best absolutely!!

Thanks a lot sir. It was realy helpful

It's extremely best examples

Thank you thank you thank you. I finally got what the heck this P-value and Alfa are….

Excellent stuff

How do you know when to use the p test

Best explanation！

You are the best!

Brilliant!

Thank You.

Great! Thank you.

God exists in you sir !

Thank Sir!

Fantastic

amazing, thanks

Perfect.

you're a life saver. i love you :((

thank you so much

You are wrong at one point , when p=alpha ,which happen seldom, this is the situation as judge is in doubt about the accused's guilt despite the evidences put, the judge would give the accused benefit of doubt . I mean you should not reject null hypothesis. Your teaching way is brilliant.
