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 😊

    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.

    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.

    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.

    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?
