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..
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
Lol after 9years I'm here learning now
Haha baldis basics
Sameee
Same here
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
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 UA-cam. I've been puzzled by this subject until I watch it today. Thanks God !! God bless you.

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
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.
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!
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😂
The lecture is %99.99 effective and practical. Unless otherwise proven. You are amazing, and thanks a lot!
So amazing... thanks
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.
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!
From the bottom of my heart, I'm saying, I wish you were my college teacher. Cause you are so so good at explaining
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!

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.
I've been having troubles with hypothesis testing for weeks and just couldn't grasp onto the concept until I found your videos.Now I feel such a sense of relief.I wish their were more teachers like you teaching statistics..then maybe more students would have confidence taking the class.
It's almost therapeutic how clearly you go over all the simple stuff, it makes it easier to keep watching :) Thanks!
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 UA-cam educators. However, your videos are truly outstanding and have captivated my attention!
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!
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!
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 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.
My university professor failed to explain this to me in 1 week and this dude let's me understand in 10 mins. My man
This guy makes things easy to understand. I really appreciate this video. Great teacher.
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.
I’ve researched so many videos to help me with my statistics class, and this is the only video that I can honestly say has helped me
the best science teacher I ever met so far, It's my great honor to watch such a detailed explaining video.
14 minutes watching this video > 2.5 weeks in my stats course at college. 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 a great teacher! I've watched a few of your videos, and your explanation of key concepts have helped me greatly. Thank you!
I went through the daunting task of figuring out hypothesis testing and still struggled with it. A few minutes of watching the video has revolutionized my insights into it. Thank you, sir!
I have heard the sign of a genius is someone who can explain complex concepts in a way anyone can understand. I'm learning more in these videos than I am in my stats class.
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.
Wow! You're so great explaining statistics. Thank you very much!
You are very welcome!

Wow! You are incredible in teaching Stats!
instaBlaster...
I have been looking for an easily understandable tutorial video for so long and I am so happy right now that I don't have to do further search any more. Thank you very much.
best teacher ever
Parisa, Also you are the best teacher in English
This is my first in college which means this is my first time taking statistics and I’m very grateful for this for this videos! Thank you Mr.
I watch your stat videos like following a thriller series.I was never interested in numbers otherwise.You are an exceptional story teller!!! Thank you so much for uploading them .
Excellent opening before we jump to hypothesis testing as such. Thank you for breaking the ideas into the simplest terms possible. i enjoyed.
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!
Oh my God finally I found a great person teaching the most difficult topic as piece of cake........great teacher
I'm in biostat right now and currently confused about everything. You are such a good teacher! I understand this much better now!!!
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.
So clear, straight to the point.. . . Thank you sir !!
I am very DISSAPOINTED!, why we don't have many people like this Gentlemen ? thank you again!
Thank you for making this so easy to understand. Gifted teacher! Really appreciate you taking the time to do this.
I can't believe the quality of these lectures is so great, and that's is free on the internet. Thank you so much!
As a matter of fact you are the best teacher in statistics I have come across till date.. thanks a lot!!
Just want to say thank's for the clear understanding of hypothesis. You are a great teacher.
Im just amazed by what i witnessed today.It is just greatness.You are born to teach cos you are soo good at it.Im blessed to have found you.Thanks a lot.God bless you
I have been following this series of yours.. and i find it very simply explained.. it has helped me through the Geostatistics part in my research! Keep it up! Cheers!
what my stats prof has taught us for 3 years i learnt in 30 seconds from this video. thanks
This gentleman is the best at simplifying and making you understand things all his lectures are amazing
I think you just saved my college career. Even my college teacher couldn't explain it as clearly as you did.
Amazing Teacher ! For teaching statistics, you dont need a PhD , you need a clear head who can help you clear your head ! . The teacher should be able to explain the concepts clearly & precisely , in a straight forward way. If a student find it easy to grasp-understand-memorise-recall-use-apply-live the statistical concepts , the teacher has done his job brilliantly ! .
The Best Statistics Teacher on UA-cam, that I have seen so far. Do we have a Nobel Prize for Statistics Teaching ? This teacher deserves it.
Watching this video a day before my summer course finals and I feel so much better. Thank you so much !!
I attended a lecture on hypothesis testing today. But I got more clarity after watching your video. Thanks a million
You are very welcome. Thank you so much!
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 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.
I have been struggling to understand this part of stats and your videos are so easy to understand! Thank you!!!
Oooh my all 7 weeks I understood nothing with your few min videos i got it all ur sooooo good at it so gifted thank you a lot. You saved me 😊
This guy is INCREDIBLE! Thank you for helping us all!
I am a post graduate in Mathematics and came across these topics many many times. But no one has explained it so easily and clearly more than you. Kudos to you sir.
Thanks so much and good luck!
2 years later you are still saving lives and stats grades... thank you for going over every step with detail
So happy you liked it!

I’m learning a lot from these videos, am currently doing Applied Stats ... Thank you so much !
I really liked this video, it makes things easy. I have been thought hypothesis and hypothesis several times, but not this way. Thank you.
He gave a thorough explanation and chunked the topic to make it easily understandable.
Good in Statistics is one thing. Able to teach Statistics and make it easy to understand is another thing. He is good. Thank you very much.
Learning statistics so deeply and at the same time, so easily. Thank you for this!
Your way of delivering the concepts is very engaging to a student's mind. Thank you.
You explain the subject so expertly and brilliantly. Thank you very much!
you have made statistics so easy to understand. Its unbelievable. God bless you....
Wow! I have an MBA and working toward a Master of Science in Health Informatics and this IS the very first time Statistics make SENSE
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
Wow! I love you so much! I wish I found your videos before I failed Stats. It all makes sense and I am actually becoming interested in statistics. You are helping so much!!! Thank you, thank you, thank you! I now have HOPE, I might actually pass this damn class. Keep it up!
You sure a calm teacher. Really love to video and understood everything. Keep the good work
All your videos are good sir. A dry topic like Hypothesis testing is made crystal clear and interesting. Thank you.
This vid has really simplified my stats studies for me. thx so much champ
You are saving my post graduate academic life right now. Thank you.
wow the content is superb. Youve done such a great help to me. Nearly quit my masters . thanks
You are an extraordinary teacher!never thought I would be so interested in statistics!
You are amazing. I have tried running away from statistics since my graduation. This is really helpful. #LongLiveInternet
You are such a great teacher. I really like your teaching style,it is very relatable and understable.
Amazing teacher! You make things so easy to understand ... im really greatful! Thankyou so much Sir!!
This tutorials are very useful for those who want to become data scientist.Great Job!!!
Well explained and easy to understand instructions. Nicely divided into small parts to follow. Thank you
this is a great instructional video. Helped me a lot with breaking down null hypothesis. Thanks!
thank you for this king, it genuinely helped A LOT
First time in my life I guess, I started understanding statistics, THANKS A LOT!!! ))
Your videos have helped me so much. I was struggling, Thank you!!!
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!
I am so thankful to you
I didn't understand during my class
Now I fully understood
My appreciation
God bless 🙏
Your tutorial helped me apply this stats concept into a data science application for a project of mine, thanks! awesome explanation!
Your videos have really cleared my worries in this course Sir! Thank you
Thank you SO MUCH for posting this. LIFESAVER for my stats final.
I have never been explained in this way.. Sir you are really a great teacher.
Dear Sir, Your lectures are good and easy to understand. Thank you so much.
THANK YOU for clearly explaining in < 15min what has taken my current professor weeks ....
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 did a great job at explaining Null and Alternate Hypothesis - thank you very much!
LOVE IT!! A very clear explanation that made me very confident on how to write the null and alternative hypothesis. Thank you, MASTER!
Welcome!
Great explanation👏🏻👏🏻 thanks so much I have final exam tomorrow & you saved me .
