Stats: Hypothesis Testing (P-value Method)

- Demonstrates the basics of hypothesis testing using the P-value method: find the test statistic which in turn gives us the P-value, then compare the P-value to the level of significance (alpha) to determine whether or not the Null Hypothesis is rejected or not.
Remember, first find the test statistic. Then, using its value, find the AREA in the tail(s). This area is called the "p-value". To find area, watch this video: • Stats: Finding Probabi...
PLEASE NOTE! I did not make a mistake by showing .0045 as the area (probability) for 2.61. Look carefully at my picture. I have shaded to the *RIGHT* of 2.61, not to the left. If you look up 2.61 on your table and see .9955 your table is assuming you want the area shaded to the LEFT of 2.61. Again, I shaded to the RIGHT of 2.61. I hope that makes sense.
Watching this 30 minutes before my stats final. Wish me luck, fellas
Andrew Green I have mine in an hour😭😭😭 how’d you do?
Same... how’d it go
How did you do?

I've watched this man's videos throughout my stats course. He's great, has the gift of teaching. Thank you kind sir.
you're teaching me more in a short video what my (heavily accented) lecturer fails to teach me in 3 hours
+John Law I was just about to comment this. We've been learning this for about 3 weeks and he taught me more in 5 minutes.
+Big One and me too my case is 5weeks haha
skievl23 No shit. You literally just explained learning.
+John Law I have a heavily accented professor as well LMAO
Saaaaame. Some sort of Middle Eastern accent here.
You explain this really well! I remember this helping me in my introductory stats course 2 years ago, and now I'm reviewing it again for my upper level stats course as a refresher! Thanks again! :)
I have been trying to wrap my brain around this for two weeks. Am in Analytical Statistics and this is a major focus right now. I finally now get it, THANK YOU!!!!!!!!!!
I just wanted to tell you that your tutorials helped me get an A in my online Stats class! I work as a student assistant in the library at my college and I pass your channel info on all the time to help other students. Thank you so much for breaking the concepts down to make it more understandable. :)
omg. finally someone who kept things simple and easy to understand. THANK YOU SO MUCH! You're one of the few people who didn't go on rambling too much. You kept things concise and clear.
You explained in 10 minutes what my teacher couldn't explain in 1 hour! Thanks :)
And mine in three hours!!!!!!🤣😂🤣😂
Three weeks*
Thanks for walking through the hypothesis testing using the p-value method. I find it very simple to grasp.
Thank you for uploading this! you are a very good instructor and I've been looking everywhere for a simplified solution to hypothesis testing!
That was one of the best 9 mins of Statistics I've ever had. I totally understand the p-value method now. Thank you very much.
Studying statistics for the first time in my final year of university.. its like another language.
you've made such a difference. THANK YOU!
im studying it for the first time too and im supposed to graduate in may, i hate it, i've always hated math
I kept getting the p-value and proportion formulas mixed up and I've been trying all semester to wrap my head around it and basically I learned it under 10 minutes because of your amazing video and simple explanations! Thank you so much!!
Excellent explanation and easy to understand. Wish I found this before my exam too. The stats book is too long and the relevant information all over the place. This is how everyone should learn hypothesis testing.
2019 and it's the night before my data science exam!!! how my lecturer didn't explain it like this is a mystery- thanks for saving me from a meltdown!!!
I have an exam next week and missed out on 2 lectures about hypothesis testing and hypothesis p-value method and you saved my life! Feeling much more confident, so easy to understand compared to all the books. Thanks for being straight to the point!
Thank you very much! I knew this all a year ago but I had completely forgotten it, and now it has all come flooding back.
Awesome 🙌 having a clear and easy to understand voice is so rare anymore! Beautiful
Thank you so much for this! For my stats homework I was assigned a series of problems and for some of them I had to use p-value method and for others I had to use the traditional method and your two videos on both topics really really helped. If I manage to get an A on my quiz tomorrow it'll be because of you :)
This video taught me more about p values in 10 minutes than a month worth of sitting in my stats class. Thank you SO much!
This video is very helpful! I've never taken stats before so I was struggling with this concept. Thanks for taking the time to make this!
Thank you for the time and effort you have put into your videos, they are greatly appreciated!
I don't usually comment on videos, but you made totally sense and now I am not confused on p-value testing! Thank you!
This is incredible! You break it down so nicely and make it easy to understand. Thanks for your help!
I like your P-Value testing approach - it is better than my college-level statistics course. With "null testing" - you get some "negatives". If you are testing a "research hypothesis", the you are almost always looking for a "one tail test". Your "research hypothesis" can be very strong by these methods. Thanks for your effort!
Use the Z score formula to calculate Z then
You use Z value table.
2.61 is a Z score and the probability for 2.61 from the table is 0.9955.
However this value is the area (1-a). So to find the correct area of the tail, you subtract 0.9955 from 1 which gives 0.0045
Thank you for the help was confused
I've been struggling with statistics, and these videos make it easier to understand. Thanks so much!
This helped alot! I have a short report to make for class and this cleared up right-tail confusion of where the P-value even came from and why.
Already saw a few videos through google threads and such, but this was straight to the point and clear. Thanks!
YOU ARE THE BEST IN ALL OF TH-cam AND ALL OF MY PROFESSORS AT TEACHING STATISTICS. THANKS FOR GETTING POINTS ACROSS SO WELL!
I cannot thank you enough for your fantastic explanation! As an online student I was struggling a bit with our text regarding hypothesis testing and P-Values, but you've made it much more clear. :)
maaan your videos are amazing, you dont miss any details to explain, i applaud you. i hope other people can learn from you
This is great man, this man is gifted and knows how slow people think hence his teaching.
Thank you very much! You have taught me in this 10 minutes more than my professor has in an hour and a half. Great Job.
Thank you for posting! I was forgetting one piece, and you cleared it up for me.
Thank you. Why don't most professors explain stats like this? Love the rhyme!!!
Proud to call him my friend. His explanations are super. best math professor in Massachusetts
gotta love this guy!! best explanations I've seen so far.
You are brilliant! Definitely following your calling this is the best explanation I've found very clear and concise. Thank you for sharing!
I can say, this is the best hypothesis explanation by far.
Ive been looking all over youtube for a video that explains this and you did that perfectly. My proffessor does not know how to teach in statistics becasue she didnt major in it so i have to basically teach my self via internet so thank you sir for doing an excellent job i finally get it my brotha RESPECT my brotha RESPECT
thank you so much for the mnemonic on go and fly. That made this whole thing so clear to me like you have no idea of. Thank you
Great explanation, the tailed tests are more convincing than any other videos available, regardless to any resources.
Literally all I could ask for in a stats video. took elementary 3 years ago and now am taking stats 252. This video refreshed my brain since my professor runs too fast. Thanks for the help!!!
Thank you so much! You managed to make something as abstract as this easily understandable! Thank You!
Great videos!!! Helped me out a lot in determining difference between traditional & p value method
This video is awesome! I missed a day of class and was a little confused. I watched this video a few times and took notes and now I totally get it. You made it very easy to understand and gave little tricks that make it easy to remember. Thank you so much!
Wow! I'm paying tuition for a graduate course that fails to teach me as much as TH-cam. Tragic.
Great Video! Cleared up so much for me!
OMG thank your sir. you are like my life saver.
I could not get it when my teacher or my friends were teaching me. you explained it so well and clearly i can now understand the stuff i need to know for my exam next week. THANK YOU!!
Excellent presentation, sir!!! You have clarified and emphasized all the important points.
I️ have a midterm tomorrow and this is super helpful for last minute notes. Thanks for the video!
Thank you so much man, I have a statistics exam tomorrow and this helped a bunch :D
Thank you so much. You just explained the whole thing in 10 minutes while my professor couldn't even explain like this in 3 hours using bunch of examples.
I seriously love you. You are AMAZING at explaining this in a simple way :D YAY
you have the beautiful and rare gift of teaching Mr. Anonymous!
i am in a statistics class and am taking my college final tomorrow morning. you dont understand how much this one video has helped me!! i have had a brilliant math tutor and professor who have yet to teach it so simple as you do. i hope you are planing to be a teacher or already are one because you are brilliant . thanks again!
-your newest fan.
Thank you so much for explaining so clearly. I was so not understanding the textbook. Appreciate that you share your knowledge. THANK YOU.
Best video out so far. I finally understood it!
This is a life saver for me in Stat right now. I wasn't aware that I could do it this way. Much easier.
Thanks for the video! I had a hard time understanding this in my class, but you made it much easier!
This was an excellent explanation of a complex concept
Absolutely love it
Thank you for taking the time to make this video. It really helped. :)
Thank you very much! I love your methods of teaching. You make it really easy to understand, and also easy to apply. Thank YOU!!
You are awesome! :-) You explain things step by step, for the most part. I had to go back to figure out how to use the Standard Normal Distribution table, but overall, I got it! Online learning is so hard when all you really have is the book to look at and it is confusing.
This helped me understand it so much better than the book. Thank you for this!
Thank you, thank you, thank you! I was stressing, trying to understand this concept. You stated it succinctly and in a manner which is easily understood! I'm glad I found your videos! Again, thanks from a VERY grateful student!!
Amazinf video. You're really good at teaching. Keeping things simple for us to understand and not go off topic like many other teachers do..
@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!
im studying for my final, that's in a couple hours, and this actually made sense... thank you.
Watching in 2022 really helped me understand about the P-value. Thank you 🙏
Wow this really helped me so much especially after the 7 minute mark! Thank you so much you explained this a lot better than my college professor did in the 3 hour lecture!!
If the P value is low, H0 must go (reject). If the p value is high, H0 will fly (do not reflect H0) what a helpful phrase. Thank you for making this so understandable!!
Extremely helpful! Easy to grasp and straight to the point. Thank you for the great video!!
Thank you for doing this. it was very easy to understand. Whoever thought to put these math videos online for free is a saint and so are you. This helped me complete my final exam. Thank you and I wish you the best. :)
Stats 226 at University, Exam #2 is in an hour. Never figured out how to do P-Values until I saw this video. Thank you.
I wish I found your videos earlier than the night before my exam... Super helpful though, thank you!!!
How did you do?
Omgsh same
Wow, love the way you explained it. Thank you!
Thanks for making this so easy to understand, brother!
You are an excellent teacher. Very thorough.
You are the Best Statistic Teacher.
you are so good at explaining! Thank you!
Well, I am doing a data science course that mentions the p value but the course doesn't really cover it in enough details. I am glad I found this tutorial. Even if it is 10 years old, it still helped. Thank you
Your teaching style is genius!
Thank you. This helped better than my professor's explanation of the subject!
These videos are a great help. Thank you.
Thank you so much! So helpful-- way better lecture than my stat teacher : )
watching this video just saved my life! much appreciated
You are simply the BEST! Thanks for sharing this, really helped me! :D
SUCH A CLEAR WAY OF TEACHING! AMAZING! THANKS A TON SIR. 🙌❤👌
Simple, brief and very understandable. Thanks so much
Great explanation. Enjoyed the video. It was helpful.
This 10 minutes video was explaining Hypothesis Testing much better than a lot of long and boring videos out there.
Thanks so much, you made a world of difference for me! Great job!
This is a great video!! Thanks. Easy to understand!!
Thank you! I'm in business stats 2 and although I am familiar with finding critical values for t and z the p value has completely thrown me off! My instructor does not give lectures (I can contact her for help), and the class is solely taught by Hawkes Learning software (which is not always direct with information). This video saved me a lot of time. I've been scouring the internet trying to figure out how I find my p-value and your video put it very simple.
great video and analogies, thank you sooo much!
Absolutely brilliant!! Thanks for the explanation of the topic. Thanks a lot!!!!!!!!
You rock man! You're way better than my Prof in explaining that stuff!
Thank you.
Greetz from Germany
These two videos are very helpful. Thank you
Thank you! This is so useful. I have a project coming up and this is great. Keep up the good work!
This is the best video!! Thank you!! Extremely helpful
