I haven't understood a single word that my statistics teacher has said to us this entire semester. Yet I understand this perfectly, on the first time. Not all heroes wear capes. Thank you good sir.
I have actually watched 4 of his videos in a stretch and still not getting bored. The Professor is a genius. He has done so much to demystify what some lecturers teach and most importantly what most students believe statistics is all about. I really appreciate the importance and relevance of ICT.
Finally, I can differentiate between z , p value, level of significance. Your lecture proved that most of the lecturers themselves are not confident about the core concept and that's why they can't explain. Thank you very much
I'm working on my master's of statistics and I've got to say this video was incredibly helpful. Some of the jargon and theory used in my classes are a bit too abstract - I really appreciate the concrete examples!
most of the statistics lecturers in universities are so proud that they dont deliver concepts well. I love your approach which makes it easy for students to understand better. Thanks and God bless you
I rarely comment on videos... but absolutely love his style..in 20 minutes..the concept is deeply deeply ingrained in my mind. He is passionate and he cares about the topic and his students. God bless you and the world have more teachers like you....we would all be much better students then. Sincere thanks again.
I am doing statistical analysis in grad school and needed a refresher. You are such an incredible instructor and I am so grateful for you! This allowed a visual representation of the P-value in a way that really allowed me to understand WHY 0.05 is used. Thank you so much!
My God, you are the best greatest teacher on earth, I don't know if there is or not anyone else that I know that teaches so clearly in detail, you should be an example to the entire world's education systems. The entire world education systems must be changed, this is how everything should be taught , instead of long boring lectures, or reading books that are so hard just to understand what they are trying to tell you, because the way books are written is very official language which I abhor, a simple concept that can take one minute to understand takes hours, because the way these evil books are written , the concepts of science, math and everything else are not hard to learn and are actually fun to learn, if it wasn't for these official languages that are used in all books, I am so sick and tired of them. This is how everything should be taught in all schools. Simple, fun and clear. They should learn from you, you are the best and made a big difference in my life, truly American teachers are the best too at teaching. But offcourse your ways of teaching makes it the 👌 best.
Man, I swear you are a f****** LEGEND, do you know how many stops I had before landing here, with no still no clue what P- Value is. Thank you man, REALLY thank you 😊😊😊😊
I swear I've been watching like 20 videos and still didn't understand P value but after this video it just clicked! I am so happy, I have seminar next week I can go there confident! You are awesome teacher much much better than my stats professor
I don't think I have ever commented on a youtube video, but you just saved me. Your content is amazing, clear, and concise. Thank you, you angel in disguise.
I have 2 weeks left of my 8 week applied statistics course and I just absorbed more info (and by absorbed I mean I actually GET IT instead of memorizing it!) in 22 minutes than I have for the past month and a half. I'm disappointed that I didn't find this channel sooner (and I looked!).. so far I have an A in the class, but it's been by the skin of my teeth and incredibly frustrating because it's online. I ask my professor questions, and his answers just confuse me more. I really want to finish strong and I think these videos are going to help me. I will be binging them all! You have a genuine gift for teaching, I can't thank you enough for sharing your knowledge with the rest of us.
I have been taught Hypothesis testing during my masters course it was difficult for me to comprehend but just listening to all your videos has made it so easier for me to abreast and digest. Well done for the great lectures
I have to agree with the other comments. 5 weeks into my stat class and I'm confused on where the math went. I narrowed it down to not understanding the p-value.... excellent video. Thank you for being so clear.
I’ve never been good at Maths - always my weakest subject at school. Now doing a Masters and a module on stats/quantitative research. This is much clearer than the textbooks and even the lecturer videos! Thanks so much for all that you do ❤️
The marjortity of my math teachers have always failed to explain why and how we use this in the real world which always leaves out key education. They have only ever focused on how to get to the answer. Luckily people like this man are here to save us!
You are so awesome! I've been struggling in my class all year because my professor only reads what is on his power points which are very similar to the information in the book. You have broken it down and made out so easy for me to understand. I was thinking that I was just terrible at at statistics. Thank you for giving me my confidence back. I wish I would have found your videos sooner. I wish you would have been my professor. Thank you so much for taking the time to make these videos and putting them on RUclips.
This is the first ever comment i am writing for RUclips Video. Simply Excellent !!! You have the Expertise, Skill to Teach. And what a Passion to explain. You are absolutely Fantastic. Was literally struggling to understand the Concept from other Teachers and Books. You have made it Simple and understand it to Core. Thank you for teaching and Please keep continuing Great Job.
Taking public health and it includes statistics. Didn't realise that it did, I would have taken something else as I am terrified of maths. My statistics lecturer basically reads the slides to us and expects us to do the rest of the work, I find your videos to be quite explanatory. The alien language I was seeing earlier on in Stats lecture suddenly makes sense and I am proud to say I can now speak alien language too.
Great examples! I couldn’t find any videos so far that explain what “More Extreme” actually means. I was so confused whether it means greater or smaller. Now I finally found one! Thank you so much.
THANK YOU! I watched 4 or 5 of your videos, took lots of notes, did practice problems, and I just made my very first 100% on a stats exam EVER! I can't thank you enough. I am taking this class for the second time and wish I found these videos sooner. Thank you so much!
Thank you soooo much. I am taking statistics for my ED.D program end of June before Fall Semester and I am sitting here at my home work station at 54 y.o. re-learning Statistics with you. Good solid teaching. Could you recommend a tutor just in case. I like that you go slow and explain each step slowly. I am smiling and hope to get an 'A.' I still need a tutor on STAND BY. Smiling.
Thank you for taking the time to break things down into very basic parts. Like others have mentioned here this video really helped my understanding after having tried to understand using different resources. I think that the reason why so many people are commenting that they understand is because its broken down in a really comprehensive manner. Teaching doesn't have to be convoluted to prove you can figure something out (as some in academia seem to think). Many thanks!
I had a very hard time understanding the p-value since no one could explain it well but I understood it perfectly well only by watching your video once. Thanks a lot .
I am benefited by this video. I am a distant education student of psychology and I have to learn statistics for the sake of doing research. The textbook does not explain in a simple, detailed way. But your lecture gives a good insight. May you do more such good lectures. Love from India.
Amazingly and clearly explained , I have struggled to understand from other sources, blogs, channels and videos as well. You have really explained it so well that instead of cramming, I am able to visualize the meaning. Really Thanks in tons and appreciate your tremendous contribution to education.
Congrats. Well done videos. I had difficulties understanding textbooks. Personally, I teach finance and I never felt that textbook writers make a diligent effort. But, this series of videos demonstrated very deep conscious effort at delivering complex concepts simply. Puts all textbooks to shame. Thanks once again. I immediately understood, while having my coffee. Without realising, i spent over an hour just following through. Great work.
This man is so gifted at teaching mathematics!! I know that when I see his face, and the dry erase markers, and a clean board, that I can learn the concept. :)
11:04 The lecturer gives the formula: for z = (x=bar -- mu)/(square toot of n), i.e., sample standard deviation. In so doing, he is conflating the terminology for sample-mean with terminology for population-mean and z with sigma, i.e., population-standard deviation, and he's omitting the very important summation-sign, capital sigma). The terminology for population-standard deviation is lower-case sigma = square root (population-variance, lower-case sigma exp 2) and lower-case sigma exp 2 (population variance) = summation of (x -- mu) exp 2)/n. The terminology for sample-standard deviation and sample variance is somewhat analogous but different: lower-case s (sample-standard deviation) = square root of s exp 2 (sample-variance) and s (sample-variance) = (summation of (x - X-bar)exp 2)/(n - 1). z is the number of standard deviations that the data-point, x, lies away from the mean, mu for the population-mean, X-bar for the sample-mean). z is NOT the conflated formula for hybrid standard deviation that the lecturer gives.
Typographical errors: 1st line: z = (x=bar -- mu)/(square toot of n) should have read: z = (x-bar -- mu)/(square root of n). 4th and 5th lines: s (sample-variance) should have read: s exp 2 (sample-variance) = etc.
I was hoping that the lecturer would explain why the population-variance has the divisor, n, whereas the sample-variance has the divisor, (n--1), but there's no hope of that because he's confused over the even more fundamental conceptual differences between population and sample.
Thank you so much for these video's. Can't say how simplified you've made something, that I built up in my head. Can't thank you enough they've really helped on the evening before my exam. 🌺
Critical value is actually the value you use for the boundary. You calculate the critical value using the alpha and the fx norm.s.inv and then you use Z value on a bell curve and to see if Z is falling above or below the critical value
how would i show in a graph a comparison of 2 sets of data? nominal number i want majority of samples to fall in is 25, first set of data is mean 22 sd 2 -- second data set is mean 23 sd 1, would i just find the z value for each and show which ever shaded area was larger shows which has the best results?
19:32 was actually something i wasted my 5 hours on and then got to this video. i was thinking actually why we subtract from 1 or not. So i was using t distribution and my crap faculty did not understand the concept himself so he assumed that we should just memorize from practicing the problems ( if subtracting from 1 works or not). Thanks to your sir, i got the concept now. T Thank you so much!!!!!!!!!
This might seem silly but much of the confusion (for me, at any rate) doesn't come from the math, it comes from the use of language. For example, when you continually use the phrase "sample data", you have to distinguish between "existing" data and whatever "new" data that future tests might reveal. The phrase "your data" confused me significantly because I kept confusing the two (existing data vs. yet-to-be-determined data) and couldn't get it through my thick skull that "my data" didn't necessarily refer to my "new data". That make sense? Probably not...high p-value...not significant. Never mind...
Correct explanations Sir can i add to your exlananations sir you know to the left tail value is consider as negative side. In the middle is the mean. Being that you dont give any specific numbers to work on the calculator now. The shaded side you have to put the numbers in the calculator to find the area sir. I like the way you are explanaing it sir. To the right is the positive side Of your explanations. You dont give any specific numbers the rules in stastics you have to find the area , the mean and the standard deviation you click the paste sign on the calculator then press enter button in your caculator. This are the step you should follow on the calculator. Frst step press the 2nd button and the next step but yon your right which is the VARS which is the DISTR scroll down the one that say inversenorm which is numbe 3 put down your area wich is isthe shaded side number then Put your mean which is 0 sometime not all the timeThen put your standard devation on the calculator then scroll down to paste and cick the enter button for you. The caculator will make you do the answer quickly.the problem wil give the numbers for the mean quick and the standard devations. Incase the problem ask you for the lower or upper some time they will give specific number for the lower shaded side just used your T84 or 83 calculator to work on it . i am using T. 84 step to find the lower value. First click on the second button and the other button to the right which is VARS wth the blue color of DISTR button. Then click on normal CDF which is number 2 then you press the enter btton which will give you for the lower value soe the number is given on the problem then theybwill ask you for your upper numbers on the right some time they will not give you that number. Acording to stastics rules they will put higer number like three 999 in the calculator then piut your mean and the standard deviation. Then clik down to paste and press the enter the calclator will give you the quick answer to work on them. Prfessor being that my phone dont give me the options to use your sign you are using to explain the problems. That why i am using the T 84 step to work on my own sir. I love your explanation so bad that is helping me not to forget this class sir thanks a lot. Please ask me question you doubt on my own explanations sir or you correct me please to make a flow with your explanations. I wish i saw this things before took this class i will take on line class instead classrom class. Thank God for my former prfessor who gave me stregth and told the class that i can do it. God was my strength. Thank you ooh God for my Hafodians sisters who were there to give me courage and strength not worry about any thing infront of me. Professr thanks a lot sir.
it took me 45 years , but I found that the lessons from my one stat class help me understand things like how they are bullshitting us in the manmade covid crisis.. by the way my SAT ACT, GRE and GMAT test scores all have put me in the tail of the normal curve- among the top 2.13%
I haven't understood a single word that my statistics teacher has said to us this entire semester. Yet I understand this perfectly, on the first time. Not all heroes wear capes. Thank you good sir.
LindyHoppingMidwife I thought the same thing! Angel in disguise... lol
same here
Thanks so much!
He is an amazing professor. 10/10 on his teaching skills
no way to believe that I coundn't understand this in a 50 min lecture but 15 video here
You're the savior of thousands of students across the globe. I thank you, sir, for such good content and lecture.

Its 4 years before, may to not see your message 😂😂😂
@@abdifatahfarahhamud6426 I know, but still
We need professors like you in Canada, I really appreciate every minute you’ve spent doing those videos.
Idk how to thank you
You're a HERO! I *finally* understand what on earth my professor had been talking about throughout the term! THANK YOU!
Despite speaking English for more than 40+ years, I only realized now the real difference between Z and T. Thank you!
Sir...I have an MAT and MBA from an elite schools. You are talented. The analogies, reasoning and explanations are all on point. Thank you.
I have been taught Hypothesis testing during my masters course it was difficult for me to comprehend but just listening to all your videos has made it so easier for me to abreast and digest. Well done for the great lectures
OMG! The expression '' more extreme'' perfectly understood. Where have you been all my life? Thank you sir!
Happy to help!
Godsend. I don't know why I couldn't find a good explanation of this anywhere else but I am thankful to have found this video
his lectures are straightforward and easy to understand, even you get distracted sometimes, you won’t get lost.
He is an EXCELLENT teacher. If I ever teach, I wanna be like him!!!

I had a very hard time understanding the p-value since no one could explain it well but I understood it perfectly well only by watching your video once. Thanks a lot .
Awesome!
i just want to thank you ! i understood none of these concepts before listening to you
I was so lost and crying by the point I found this video. I finally understand it thank you so much.

thanks sir
Once again Thanks Sir

Its really depressing when you're watching stat videos like this at midnight because you don't get what a word your teacher is saying.
that's life brother hehe
we pay them to teach us nothing lmao, my professor doesnt even do lectures, the TAs do.
this man saved my life
you are not alone
Thanks!!!!!
fallen in love with your teachings, its incredible how clear it is Thank you
You're an angel sent from heaven. Thank you so much man
I wish I had found you sooner. I learned so much from you. my stats teacher is nice but just so hard to understand. great job!
" And I will get to that, whenever I get to that". Love this attitude of that angel face human being
@15:23 what you all came here for
Gracias!
thank youuuuuuuuu
thank you :)
Thank you.
Sonnnnn 💪🏾
This man is God's gift to math. This is THE ONLY reason I understand anything.
Congrats. Well done videos. I had difficulties understanding textbooks. Personally, I teach finance and I never felt that textbook writers make a diligent effort. But, this series of videos demonstrated very deep conscious effort at delivering complex concepts simply. Puts all textbooks to shame. Thanks once again. I immediately understood, while having my coffee. Without realising, i spent over an hour just following through. Great work.
Glad it was helpful!
thank you!!! Yesterday the p-value was killing me softly... today there is hope I will survive the statistics course.
It's been 3 weeks of trying to find someone I can understand thank you.
Hands down the best review I've seen on this. Thanks.
You are awesome.. feeling feeling lucky to have found such a brilliant and motivated teacher. A big big thank you!
This man is so gifted at teaching mathematics!! I know that when I see his face, and the dry erase markers, and a clean board, that I can learn the concept. :)
The only video I could find that could clearly explain p-value.
Awesome thanks!
Damn, I don't know if it's me or your technique but it is all making sense. I think your teaching is spot on!
Good teaching!
I have severe ADHD and it has taken me forever to find a video that worked!
11:04 The lecturer gives the formula: for z = (x=bar -- mu)/(square toot of n), i.e., sample standard deviation. In so doing, he is conflating the terminology for sample-mean with terminology for population-mean and z with sigma, i.e., population-standard deviation, and he's omitting the very important summation-sign, capital sigma).

My statistic professor should learn from you how to teach students. Love from Sri Lanka
the way you explain things is just so easy to understand compared to my professor!. thank you so much
Finally someone who can explain this !!!!! Best video on this topic
I have to say .. you are ammmmmazing... omg you saved my life. I was going to fail in my exam.. Thank you soo nuch
Thank you so much for these video's. Can't say how simplified you've made something, that I built up in my head. Can't thank you enough they've really helped on the evening before my exam. 🌺
Every Statistic students should be subscribing to your channel
P value:
LTT: norm.s.dist(Zc,1)
RTT: 1-norm.s.dist(Zc,1)
TTT: 2*(1-norm.s.dist(abs(Zc),1))
OMGosh... my professor spoke jibberish, but you make it very clear! Thank you!
Your lectures are great and way ahead of their time as when they are created.
Thanks so much!
This is becoming clearer sir. Thank you
Thank you for your videos ,it’s really helping me to understand statistics . I’m so appreciative,thank you
A good dancer knows the right time to leave the stage,,it's incredible so good and understandable❤
Excellent way explaining a confusing concept !! Thank you very much !!
Where were you when I was doing my graduation in Statistics 😭😭
Thank you so much sir and I really mean it :')
the best teacher and explanation ever! hello from Russia!
Thank you sir. Statistics is getting very confusing for me and this video help me to clear some things up.
Critical value is actually the value you use for the boundary. You calculate the critical value using the alpha and the fx norm.s.inv and then you use Z value on a bell curve and to see if Z is falling above or below the critical value
how would i show in a graph a comparison of 2 sets of data? nominal number i want majority of samples to fall in is 25, first set of data is mean 22 sd 2 -- second data set is mean 23 sd 1, would i just find the z value for each and show which ever shaded area was larger shows which has the best results?

So i was using t distribution and my crap faculty did not understand the concept himself so he assumed that we should just memorize from practicing the problems ( if subtracting from 1 works or not). Thanks to your sir, i got the concept now. T
Thank you so much!!!!!!!!!
Very impressive. His clarity is excellent. He understands the concepts that need emphasis.
Best explanation that I have come across. Kudos
having a stats quiz tomorrow and you just saved my life!
Please I’ll love if you tutorials on hypothesis testing are in a sequence ..
very well explained
This might seem silly but much of the confusion (for me, at any rate) doesn't come from the math, it comes from the use of language.

That make sense? Probably not...high p-value...not significant. Never mind...
Thank you for nice explanation. I am back to study after 12 years for my Six sigma exam. Helped a great deal.
Amazing video. Great refresher on extremely important, fundamental concepts.

Yeah man you are great.... You cleared my concept about p-value.... Indeed you are a great teacher... Greetings from Pakistan
This is brilliant teaching! If there's a Pedagogic Hall of Fame somewhere, this guy's statue should be at the front door!
I can't believe I'm learning all of this for free
it took me 45 years , but I found that the lessons from my one stat class help me understand things like how they are bullshitting us in the manmade covid crisis.. by the way my SAT ACT, GRE and GMAT test scores all have put me in the tail of the normal curve- among the top 2.13%
That is a very helpful video that made me understand the P-value very well. Thank you!!
One of the best video of p value, thank you very much
I may just pass this online course because of you. thank you, sir!!
AM ONLY 2 MINS INTO THE SESSION AND I CAN TELL ITS GONA BE A GOOD RIDE. KEEP ON SIR
You are my (statistic) lifesaver today
