Statistics 101: Type I and Type II Error Examples 

Great help Brandon thank you. One simple way that my small brain can remember which is a type 1 and which is a type 2 error: - Reject, (which is one word, is a type 1 error) - Not reject (which is 2 words is a type 2 error) Not a very complicated way of learning but it helped me anyway 😊

Why and how is it that colleges and graduate level courses manage to make the subject of mathematics and statistics so difficult to grasp? Thanks Brandon for your work. It is materials like this, available for free on the internet, that set people free from the shackles of terrible teaching methods. Thanks again!

The best students are resourceful and learn how to help themselves! Good luck! I know you will do GREAT. - B

I truly appreciate how you simplify and repeat with clarity. I am a doctoral student in the Public Health program in Walden University. I have subscribed to all of your videos and last night I fell asleep listening to your videos. I have a great deal of anxiety about statistics. This helps so much. Great job!. God Bless you Brandon Foltz.

Best teachers are slow learners; by their nature they develop the patient and humility needed to explain things well to others. Also, since they are slow to learn, they spend more time studying a concept hence will understand the technicalities well...I am glad to be one and be part of this series(probably done by one, too). Hope I have not committed type I or type II error. Thanks so much for this series...

Many thanks Brandon, you are God-sent. The way you explain stats makes it seem much more fun and easy to understand and relate to our everyday life.Before, I spent too much time to grasp type 1 and type 2 errors but in vain while just 10 mins of your presentation was enough,cant believe it! I wish most lecturers had the skills u have to make learning easy,more fun and related to our everyday life. Keep it up ,Sir.

brandon, I am a prduction manager in a big home appliances factory.. now I am studying on 6 sigma concepts and your videos are very helpfull . great thanx

You are so very welcome! Thank you for watching. It is a pleasure to help people out. Never stop learning! - B

Thanks for showing me the type 1 & type 2 errors, and the null hypothesis. I am having some issues concerning this. Taking a statistical course in college, and with your tutorials I have gotten a better understanding of this mathematical method of doing statistics. Again thank you. Donald Davis

Part I and Part II are excellent summaries of Type I and Type II errors. It's a good introduction or refresher on the subject. Thank you.

really very simple way to teach type 1 & 2 erros. thanks Brandon..you are a great teacher..

This gives me hope of passing my class! Thank you! So much better than my textbook.

Part II is an excellent continuation of Type I and Type II errors. Thank you!

The positivity from this video is what I needed..

I have a test tomorrow for my MBA Core Stats class, I kept thinking:out of this classroom, nobody can help me...I'm screwed! But with I little research I found your videos... Thank you!!!!!

Thank You very much for your encouragement. This video really helped me with type 1 and 2 hypothesis errors. I am doing very well in my class partly because of videos on youtube like yours. Keep up the great work. You all are appreciated by me and millions of other students.

Muchas gracias, Brandon. Me han ayudado mucho en mis clases de Salud Publica.

Hello Brandon , you're doing a tremedous job thank you so much , may i suggest a formulation ? wouldn't be simpler to say : Error type I : rejecting the null Hypothesis when it's TRUE and Type II : Not rejecting the Null hypthesis when it's FALSE. , thak you soo much.

Excellent stuff Brandon - thx vm. What would be great is if you could somehow label the titles with a number to indicate which order they should be viewed in, although the titles do indicate order. Might be that you have catalogued somehow and I just don't know how to see that in youtube !

Great great intro….And the construct of your videos are amazingly helpful. by far one of the easiest, if not the easiest to follow on youtube. Thank you very much. I'm studying for my stats spas test tomorrow.

you are indeed the best to explain concepts . i want to become one of the best data scientists in the world. please guide me and advise me the track and lecture material and books that could help

super lecture, where the theory goes into the practice, really applicable, thanks

thank u soo much Brandon for putting in your efforts in making such lucid videos on hypothesis testing... great work!

Gosh, I can't believe I'm breezing by with so much better understanding. THANK YOU

Very excellent and great video to let people realize the materials

Hello Brandon Thanks for providing some brilliant stuff for learning. I tell you I am a working person in business reporting field and trying to develop new skill 'Machine Learning' so stats is a prelim task to Machine learning. I am able to learn the mathematics behind Linear Regression from this course. I would request you to please try to make videos on other Machine learning algorithms as well. Since its extremely easy to understand from your videos. Thanks Rohit Thakur

Your videos are great, please keep up the good work. Even though my online professor has included videos about these topics, I am able to learn off of your videos instead of his.

Hi, Brandon. I think the government agency should prove that the bottle contains equal or more water into the bottles because the interest of people is not affected by the bottles containing more water. So the H0 should be >= and the Ha

Thank you for the hopeful words at the beginning

Forever grateful mister Foltz 🙏🙏🙏

Dear Brandon Thanks for these wonderful videos. I have a query though.Would really help if you can answer it. I am not able to grasp how you are selecting the null hypothesis for any problem. If I interchange the null and alternative hypothesis how would it impact my outcome?Would it be a wrong process?

Outstanding presentation. Thanks Brandon, Al

100/100 and You are indeed the best who knows how to teach

Thanks a lot for your work Brandon I really appreciate it please continue doing a great job

I finally understand ... thank you so much !!!!

You rock. It would be an error to stop making these videos!

absolutely useful ...10 times better than what i get from my lecturer's mouth ...

Oh, for the play lists, just search "statistics PL08 Foltz" and RU-vid will give you the play list for hypothesis. If you want another play list, search statistic PL07 (or PL06, PL05) and this will give you different play lists for different categories.

Since the government agency's aim is to make sure that the bottles don't contain less than what the label says, shouldn't the alternative hypothesis be that u < 355?

Thank you so much Brandon!

Superexcellent presentation! Thank you so much!

you are truly a life saver

Which level/difficulty is this channel statistics? basics or intermediate?

so, at 11:20 which sentence state that the null hypothesis is less than or equal to 2.3km^2?? cause i would've had put "=" but why?

great examples! Thank you

This is good because some of us do not remember this. After all, we have been out of school for a long time.

Brandon, you are awesome. Thanks beyond words. Love you

Thank you. this is great.

thank u soo much brandon sir

Awesome! Thank you so much for all these videos.

Very helpful, thank you

Awesome videos, but could you shorten your video a little bit? There is way too much to learn for guys like me. Great work,Thanks man.

great job. thanks

This was helpful thank you!

Thanks a lot

Thank you somuch,

Thanks

May god bless you......

Null Hypothesis: Brandon Foltz is the best Alternative Hypothesis: *Does Not Exist*

Fabulous! Thank you!

type 2: you fail to identify a problem when there is something wrong
