The student will learn how to write the null and alternate hypothesis as part of a hypothesis test in statistics. We will work several examples so that the student gains an understanding of how to work hypothesis testing problems step-by-step..
Lol after 9years I'm here learning now
Haha baldis basics
Sameee
Same here
This is cure to my depression
fucking same
Wow!
I’m legit depressed because of stats. Hope I get help here
you know right
Exactly!!!! Huuuu. Breath😂
I needed this spelled out in laymen's terms. Thank you so much for making analyzing data seem possible. That is so vital to allow more of these methods to hang out in my head without something important being shoved out.
He gave a thorough explanation and chunked the topic to make it easily understandable.
Thank you, for these videos. I am in statistics for my Master's and these videos have really helped me understand that which confused me in the book. I agree with all the comments that say you are a very effective teacher.
This is such a great explanation, I couldn't understand which was the null and which was alternative when trying to apply it to examples (to be fair I'm also unfamiliar with the term "status quo"). But this really cleared it up, thank you! You are a great professor!
You are amazing. I have tried running away from statistics since my graduation. This is really helpful. #LongLiveInternet
wow! You are so clear and easy to understand. such a big thank you!! this is soooo helpful. I've forwarded the link to my classmates to help them as well.
Thanks to you I can sleep peacefully
Excellent videos you have a great skillset for teaching. Your videos are very informative and clear to understand.
Thank you very much!
more clearer than before thanks a lot sir
@Math and Science: Fantastic , love to watch and learn. But not able to find the next video, jumping directly to P-values. Could you please share the link of next video. Appreciate!
great job. Well explained
Thanks a lot sir, for such kind of wonderful explanation..
very well explained thank you!
Great instructor
Thank you!
Best , it is you
THANK YOU!!!
You are the kind of teacher who make students interest in the subject. You are a great teacher.
Unnikrishnan B Thank you so much!
+mathtutordvd I agree, fantastic.
I love stats and you deal with information at an awesome pace so as not to lose my interest.
so true
I really appreciate it!
Agreed!
i learned more in this video than the last month of my stat class. Easily understandable
agree....
agreed
ikr!
couldn't agree more
Same
After watching a couple of video in statistics posted by you mister, I wouldn't hesitate to say that my level of confidence in you is 99.99999%. The reason I say this is throughout my years in college almost four decades ago, plus watching tons of video posted by others about statistics and other subjects I just absolutely can't find anyone who can explain a subject so clearly as you do. I wish each and every teacher/professor out there could do like you do so millions of students wouldn't have any severe headache. Sometimes I asked myself the question is it true most college professors really want to teach you the best ways or they just "sometimes" just want to make it complicated to give students hard time? I doubt it.
About Null and Alternate Hypothesis, nobody explains this subject so easy to understand as you do, including books and other video on RUclips. I've been puzzled by this subject until I watch it today. Thanks God !! God bless you.
janviergalle .
no.. the professors just want to get paid like hookers while they hate their job but like the money.
if they really wanted their students to learn they would find these videos and play them in class. but then why would they get paid so much, or be hired at all.
.
nowadays learning should be watching videos and doing exercises then tests, all on mobile unless otherwise needed. it could make schools and universities almost free.
i dont know if its possible to only take the tests and self study but thats the way to go. u get a better teacher when u take the worlds best on utube than the teacher who hates his job and sux on purpose.
@@dankadybong7948 so true
This guy used to work for NASA. I bought his stat course and it helped a lot
how
LOL
Oh
What's his Stat course?
Eden Birku got to mathtutordvd.com
He has all his videos that you can purchases or be a member for $19 (I don't remember) .. I prefer the memebership because u gain access to all the videos
As Enistein once said, "if u can't explain it simply, that means u don't understand it so well".. After watching this i am able to tell my friends about this concept in a simple way.
Wow! You're so great explaining statistics. Thank you very much!
You are very welcome!

Wow! You are incredible in teaching Stats!
instaBlaster...
The lecture is %99.99 effective and practical. Unless otherwise proven. You are amazing, and thanks a lot!
So amazing... thanks
best teacher ever
Parisa, Also you are the best teacher in English
I've been struggling with stats this entire semester (even with tutoring, and countless hours online and in the library) and this is really the first time I have found a clear and understandable way to learn the concepts THANK YOU SO MUCH!!!!! I will be using every video to assist me in my preparation for my upcoming exam and final this semester. WISH I WOULD HAVE FOUND THESE VIDEOS EARLIER!
From the bottom of my heart, I'm saying, I wish you were my college teacher. Cause you are so so good at explaining
you are making maths (stats) so easy....
I don't know how much effort you are putting on the backend....it's amazing
Thanks for everything.
you deserve more.
In your words, You are melting the CONCRETE..
Donate or just pay him
It is his source of income and the only thing we could do
I learned more in 2 15 minute videos from you than 18 weeks of college level stats instruction. Thank you so much for not assuming we know things already. I only ask to put the link of the next lesson in the description of the video so I can make sure I am not skipping anything. You are awesome and your care for being thorough and easy to understand flourishes. Thank you soooo much.
WoW! You made it very easy. I have been thinking How will i understand this. My Professor has taught me this many times. But could not understand him but You did miracle . I understand within two minutes.
This video was very helpful, but I really came to the comments to say that this guy looks/sounds like Joey Gladstone.
Shelby S lmfao dead ringer
His hair reminds of Saul Goodman form Breaking Bad
This guy makes things easy to understand. I really appreciate this video. Great teacher.
So clear, straight to the point.. . . Thank you sir !!
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.
Dear Sir, Your lectures are good and easy to understand. Thank you so much.
SUPER HELPFUL, I REALLY THANK YOU ❤and I wish that my professor can watch this video to learn how to teach in a clear, fast way. 🤩
Thanks a million. You made it real simple to understand. Any videos on actually doing a hypothesis test?
I want an event studies series tbh, would help me with my dissertation.
can you please help me with this question?
Q1. A school conducted special classes to help students with poor verbal english. Each student was required to give a test twice, once before starting the classes (Test 1) and once again after completing 4 weeks in the class (Test 2).
Let Y1 and Y2 be the scores in Test 1 and Test 2 respectively.
Let Y = Y2 - Y1. Hence, if the population mean μ for Y is equal to zero, then the special classes have no effect on the average.
It is planned to test the null hypothesis of the class having no effect, against the alternative hypothesis that there is a positive effect due to the classes.
Student Test 1 Test 2
Abhay 5 8
Bhumika 3 10
Charan 2 5
Dinesh 4 7
Variable Number of Students Mean Standard Deviation Standard error
Y 4 4.000 2.000 1.000
a. Set up the null and alternative hypothesis
b. Are the classes beneficial to the students? Make a decision using Significance level as 0.05.
c. State whether the following statement is true or false:
When we make a decision using Significance level = 0.05, this means that the special classes are truly beneficial, but there is a 5% chance that the classes are not beneficial
You should have been my Statistics Professor.
I am so thankful for teachers like you that actually enjoy teaching and students. Thank you so much. It is very appreciated by a lot of people.
Thank you so much sir this helps me a lot, you explained it thoroughly
thank you for this king, it genuinely helped A LOT
is there anymore video on typeI and type II error?
God bless you so much ❤.... You explain so well and fluently ❤❤❤ Thank you so much.. I wish I could like all your videos a hundred times because you ❤ highly deserve it ❤❤
Please never stop making these videos because you truly are teaching us. Honestly it’s a talent to be able to teach in a way that makes everything make sense.
I hope I can be this good at something one day.
On behalf of all of us in the comment section: Thank you and BLESS YOU we hope you’re doing well.
Thank you so much!
Jason, MathAndScience.com
An absolutely great teacher with amazing delivery skills!!! I got an MSc level exam tomorrow for analytics and I am revisiting statistical basics via your tutorials. May God bless you abundantly!
wow the content is superb. Youve done such a great help to me. Nearly quit my masters . thanks
wow you are so powerful in communicating clearly . Thank you so much
You're a legend
Come teach in Australia!
I am very DISSAPOINTED!, why we don't have many people like this Gentlemen ? thank you again!
Helping me with my grad. research statistics class... Thank you!
This is helping me with my dissertation. My professor told me I need to do stats for mine to get a higher grade than what I'm doing now lol.
this guy is better at teaching than my tutor at uni, holy
am very lucky to have found your videos.........your explanations are good n understandable....
Henry Sikanyika do you have a complete set of videos of this great stat teacher? I want to have a copy of all his videos on stat pls.
Thank you, soo much enlightment on the topic ,been off help ,good job!
I think I have some misunderstanding about "no longer". Is "no longer" means "not more than" or it means "never again"? Or it depends on the context? Thankyou
If the question is about the teens and sleeping then it means "not more than".
You are a great teacher! I've watched a few of your videos, and your explanation of key concepts have helped me greatly. Thank you!
Thank you my Statistics class has been switched to online, my teacher does online lectures but he talks to fast , makes a mess on his white board , you cant understand the man nor read his gibberish. He doesn't introduce things he's just too fast and doesn't explain well at all. So it hasn't been easy for me having to self teach myself during this Quarantine but you have made it a breeze I am understanding so much and I am getting caught up with the class I just want to say thank you and you have helped me so much.
here from corona
Same here! My professor has the longest lectures and breaks down things you don’t know.
good video but it sucks how we have to pay to watch the rest of the hypothesis videos.
to get other stuff checkout Professor Leonard
Thank you very much , you make Statistic exciting!
great video - wish you were my everyday lecturer but i would really appreciate it if you would compile these videos as a complete series as it is very difficult to find the next video in the correct order
I just want to say you are amazing at explaining this material. You’re the definition of what a teacher should be like! Thank you so much
Thank you so much!
Where is the next vedio of this?
I like that you apply law to this as an example because my major is philosophy and legal studies so it helps me understand better!
why couldn’t you have been my stats professor💔
I must express my appreciation for the accuracy and clarity with which you've covered the subject in your lecture. Typically, I lean towards learning from textbooks rather than online resources, and I'm not usually inclined to follow RUclips educators. However, your videos are truly outstanding and have captivated my attention!
Excellent! One of the major virtues of this series, unlike so many other video stat lectures, is that you take nothing for granted as regards the viewer understanding the exact use of stat language. You are very explicit in spelling out every concept leaving no room for doubt. Well done!
This guy is so much better than my instructor, .can you be my tutor?
Amazing teacher! You make things so easy to understand ... im really greatful! Thankyou so much Sir!!
In the example that the school board claims at least 60% of the students bring a phone to the class and then a teacher says it's too high: You formulated the teacher claim as p
exactly, I think it should be that p >= k, where k < 60
what my stats prof has taught us for 3 years i learnt in 30 seconds from this video. thanks
thank you so much, my exam in few hours and his help alooot
excellent lesson and teacher, but BRUUUHHH you need a fresh fade up fam that cut you got going on bothered me the entire time!!!! hmu if you want a fresh edge up
Roger Garcia LMFAOOOO
14 minutes watching this video > 2.5 weeks in my stats course at college. THANK YOU!
thank you for making this video!!!!! I found a way that might also be helpful, that is if you are not sure what the Ho is. You can look at the Ha and it might help you to find the null hypothesis
As a matter of fact you are the best teacher in statistics I have come across till date.. thanks a lot!!
very well explained, thanks for the help sir
Finals coming up so y’all know the deal
this man really is floating me through my college math classes lol
So basically I just watched an entire 4 years of University study in just less than 15 minutes?
Thank you from 2019....
Can't imagine these videos are free...You safe my grade
This guy is INCREDIBLE! Thank you for helping us all!
hello, I have a doubt regarding the hypothesis writing i.e., in my analysis, I have one DV(Dependent Variable) and two IV'S(Independent Variable). By doing regression I want to know which IV has more effect on DV, in this case how should be my alternative hypothesis??
Hypothesis testing made simple. Cheers
These videos have helped me so much for my test tomorrow!! Thank you so much!
I hate this. I want a simple step-by-step instruction from start to finish on how to understand the null hypothesis and how to figure out the formula and every single teacher EVERY SINGLE ONE. *_*Here's and example.*_* NOW INSTEAD OF FIGURING THE FIRST ONE OUT FROM START TO FINISH *_*Here's a SECOND example.*_*
USELESS, ALL OF IT, USELESS, I NEED START TO FINISH, CLEAR, BASIC, UNDERSTANDING.
My autistic brain cannot handle the interrupt.
Great explanation👏🏻👏🏻 thanks so much I have final exam tomorrow & you saved me .
Heh wat kind of researcher believes the average teen sleeps more than 10 hrs, i sleep no more than 5 hrs everyday bc of school
Quick Question (test tomorrow): Is it relevant whether which one is the null and which one you choose to be the alternate? I feel like its subjective
It might be late, hope you passed your test. But the null hypo. should be the default one not the newer assumption
My university professor failed to explain this to me in 1 week and this dude let's me understand in 10 mins. My man
I really liked this video, it makes things easy. I have been thought hypothesis and hypothesis several times, but not this way. Thank you.
Thank you so much for this clear understanding. I was giving up, so lucky I clicked on you. I will be following you. I appreciate with all my heart that you make these videos for those of us who struggle.
You are so amazing. You explain so clearly and I don't thing I'll ever have any confusion. Thank you very much.
Thank you SO MUCH for posting this. LIFESAVER for my stats final.
"When do you think people die? When they are shot through the heart by the bullet of a pistol? - No... It's when… they are forgotten!"
U sir will live forever
where is the next lesson? I want to solve a whole problem?
$$$$$$$$$$ It will cost you! lol
I don't know what was the problem of those who disliked this video. His method is the best. Going into details, pointing to minor issues and recapping what has been told. Thanks so much. I wish I could have found this channel right at the beginning of my business statistics class.
Thanks so much. I appreciate it!
So, my question is about how you write the null and alternative hypothesis. My teacher says that you cannot use less or equal ≤ or more or equal ≥ when you write the null hypothesis for example
H0: p ≤ 0.01
Ha: p > 0.01
My teacher says this is invalid and it should be
H0: p = 0.01
Ha: p > 0.01
But in introductory statistics 4th edition mentioned that you can use both, page 457 "(Note that some practitioners write H0 as a simple statement of equality, even with > or < as the symbol in the alternative hypothesis. This practice is also acceptable.)"
Am I misunderstanding something?
I'm in biostat right now and currently confused about everything. You are such a good teacher! I understand this much better now!!!
