Statistics 101: Type I and Type II Error Examples
Statistics 101: Type I and Type II Errors - Part 2.
If this video we look at what happens when our data analysis leads us to make a conclusion about a hypothesis that turns out to not align with the actual condition of the population under question. These are called Type I and Type II Errors in statistics. There is no computation in this video as it is purely conceptual and aimed at basic understanding.
We walk through three example problems including in-depth discussions about their interpretations.Verbal explanations of Type I and Type II Errors can be a pain because the language often involves double negatives and phrases that seem to mean the same thing but are different! Due to this we go slow and look for patterns as we proceed, Enjoy!

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

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.
You are so very welcome! Thank you for watching. It is a pleasure to help people out. Never stop learning! - B
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
really very simple way to teach type 1 & 2 erros. thanks Brandon..you are a great teacher..
The positivity from this video is what I needed..
Muchas gracias, Brandon. Me han ayudado mucho en mis clases de Salud Publica.
Part II is an excellent continuation of Type I and Type II errors. Thank you!
This gives me hope of passing my class! Thank you! So much better than my textbook.
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.
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
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.
100/100 and You are indeed the best who knows how to teach
Gosh, I can't believe I'm breezing by with so much better understanding. THANK YOU
Forever grateful mister Foltz 🙏🙏🙏
you are truly a life saver
thank u soo much Brandon for putting in your efforts in making such lucid videos on hypothesis testing... great work!
Thank you for the hopeful words at the beginning
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.
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!!!!!
super lecture, where the theory goes into the practice, really applicable, thanks
Outstanding presentation. Thanks Brandon, Al
Thank you so much Brandon!
Very excellent and great video to let people realize the materials
Brandon, you are awesome. Thanks beyond words. Love you
Superexcellent presentation! Thank you so much!
Awesome! Thank you so much for all these videos.
Thank you. this is great.
Thanks a lot for your work Brandon I really appreciate it please continue doing a great job
great examples! Thank you
Very helpful, 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.
This was helpful thank you!
thank u soo much brandon sir
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.
absolutely useful ...10 times better than what i get from my lecturer's mouth ...
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 !
Thanks a lot
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
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
Thank you somuch,
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
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.
I finally understand ... thank you so much !!!!

Fabulous! Thank you!
May god bless you......
Oh, for the play lists, just search "statistics PL08 Foltz" and KZread 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.

sherri Thanks sherri! I wish KZread did a better job with playlists. Maybe someday...lol Best, B.
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?
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?
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?
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.
Null Hypothesis: Brandon Foltz is the best Alternative Hypothesis: *Does Not Exist*
Which level/difficulty is this channel statistics? basics or intermediate?
type 2: you fail to identify a problem when there is something wrong
