Statistics 101: Type I and Type II Errors

Statistics 101: Type I and Type II Errors - Part 1.
If this video we begin to talk about what happens when our data analysis leads us to make a conclusion about a hypothesis that turns out to not align with the actual state of the world. 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 start out by looking at two thorough non-statistical examples; the fire hypothesis and the andon hypothesis. These examples set the stage for understanding Type I and Type II Errors in statistics by providing situations you can reference easily. In Part 2 we will do the same thing but with proper statistical problems. Enjoy!

    i'd like to think of type i and type ii error as "the error of acting" and "the error of not acting"

    This once happened to me. I had to decide between making a type I error (called the fire dept and got embarassed that it was a small fire that i could easily put out with water) or ignore it and the small fire continue to burn and turn into a whole house on fire. The cost of the type 2 error was must greater than the cost (embarassment, inconvenience) of a type I error.

    I really appreciate your videos; your approach and your thoroughness are very helpful. I also think it would be worthwhile to add the choice of speeds so that students can listen at 1.5X or even 2X speed. This would be very beneficial if I am doing a review of material that I have already viewed, or if I have a shorter time to listen--like when getting ready for work or when out on a power walk and my time is truly limited. Thank You!!

    Your teaching are thorough, unfortunately I found your video collection in the last 2 weeks of my Stats class. Maybe you should start teaching some of these online classes? When I have questions for my professor they respond with screenshots of the answers. I sit back in my chair and hesitate to promptly reply with an email. When you ask why something happens or to further explain the application of these processes my teacher simply replies that it is a fast pace class and to not worry about this process? First and last time I take an online class. Education system.... Thank you again Brandon Foltz your video gives some depth and application.
