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..
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 TH-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
i learned more in this video than the last month of my stat class. Easily understandable
agree....
agreed
ikr!
couldn't agree more
Same
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
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!
The lecture is %99.99 effective and practical. Unless otherwise proven. You are amazing, and thanks a lot!
So amazing... thanks
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.
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!
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
From the bottom of my heart, I'm saying, I wish you were my college teacher. Cause you are so so good at explaining
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.
Lol after 9years I'm here learning now
Haha baldis basics
Sameee
Same here
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.
Wow! You're so great explaining statistics. Thank you very much!

Wow! You are incredible in teaching Stats!
instaBlaster...
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.
best teacher ever
Parisa, Also you are the best teacher in English
This guy makes things easy to understand. I really appreciate this video. Great teacher.
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!
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’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
My university professor failed to explain this to me in 1 week and this dude let's me understand in 10 mins. My man
Dear Sir, Your lectures are good and easy to understand. Thank you so much.
what my stats prof has taught us for 3 years i learnt in 30 seconds from this video. thanks
I am very DISSAPOINTED!, why we don't have many people like this Gentlemen ? thank you again!
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
I'm in biostat right now and currently confused about everything. You are such a good teacher! I understand this much better now!!!
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!
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 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!
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.
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!
Oh my God finally I found a great person teaching the most difficult topic as piece of cake........great teacher
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!
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
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.
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.
This gentleman is the best at simplifying and making you understand things all his lectures are amazing
wow you are so powerful in communicating clearly . Thank you so much
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!

Just want to say thank's for the clear understanding of hypothesis. You are a great teacher.
He gave a thorough explanation and chunked the topic to make it easily understandable.
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.
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
This guy is INCREDIBLE! Thank you for helping us all!
you have made statistics so easy to understand. Its unbelievable. God bless you....
You are saving my post graduate academic life right now. Thank you.
thank you for this king, it genuinely helped A LOT
Maths can be so interesting if you have the right teacher. Thanks for sharing this video!!
You are very welcome!
i can listen to your lectures on and on and on............There is no "booring" and "not understanding" terms in your class.
How many of you accept this. Give me a like.
Incredible teacher.
being able to actually see you have see the question and also have you go over them instead of having one question and making all these graphs and all really makes you a better source. sorry for the run on sentence
Thank you for making this so easy to understand. Gifted teacher! Really appreciate you taking the time to do this.
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 .
Where has this guy been my whole life? If every math teacher were like him, it would be the cure to math anxiety🤩
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!
Great explanation👏🏻👏🏻 thanks so much I have final exam tomorrow & you saved me .
I really liked this video, it makes things easy. I have been thought hypothesis and hypothesis several times, but not this way. Thank you.
You're a legend
Come teach in Australia!
Thank you so much sir this helps me a lot, you explained it thoroughly
I think you just saved my college career. Even my college teacher couldn't explain it as clearly as you did.
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 😊
9 years later, this is the best teaching video I had ever seen
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
Every statistics students really needs you at their conner. You are a life safer ❤.
Amazing teacher! You make things so easy to understand ... im really greatful! Thankyou so much Sir!!
Excellent opening before we jump to hypothesis testing as such. Thank you for breaking the ideas into the simplest terms possible. i enjoyed.
this guy is better at teaching than my tutor at uni, holy
I am so thankful to you
I didn't understand during my class
Now I fully understood
My appreciation
God bless 🙏
Can't imagine these videos are free...You safe my grade
Your method of teaching is so interesting.You have made null and alternate hypothesis so easy for me to comprehend. I therefore salute and make a hearty cheers for you.I hope I could reach you for other statistical problems I don't understand?. Thank You.
Learning statistics so deeply and at the same time, so easily. Thank you for this!
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!

You better continue teaching, Mr. Spectacular Teacher. people are dependent on you, You are responsible.....Best regards
You are a great teacher. Big thanks from Kenya!
thank you so much for making this so easy to understand. you are the best teacher for statistic.
I have never been explained in this way.. Sir you are really a great teacher.
Thanks so much! First Part of our Stats and Prob exam is gonna start tomorrow. I havent been paying much attention to our subject teacher cause the way she teaches is too complicated. She just copy paste on whats in our or her textbook. She does expound it more but not enough though. So thanks to you Im saved.
You are such a great teacher. I really like your teaching style,it is very relatable and understable.
You are a great teacher. Because you make lesson easy and I clearly realized.Thanks.
Thank you so 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!
Your videos are easy to understand. Thank you. I am beginning to hate my stats class because of the poor quality of videos that are included.
You are an extraordinary teacher!never thought I would be so interested in statistics!
Thank you SO MUCH for posting this. LIFESAVER for my stats final.
c and alfa, H0 and Ha is very well explained. having said all, the final check to accept or reject the hypothesis is left unanswered.
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!
