So this is the next video in our series about the analysis of variance, or ANOVA. In Part 1 we dismantle an example problem using illustrations and charts to understand exactly what is going on "under the hood" in a One-way ANOVA.
Part 1: Conceptual Background w/ Example Problem
Part 2: ANOVA step-by-step calculation in Excel ( • Statistics 101: One-wa... )
There are several types of ANOVAs. In this video we will be focusing on what is called the One-Way ANOVA and in a later video we will discuss the Two-way ANOVA. It is important to note that One-way ANOVAs go by other names such as the Single Factor ANOVA and in experimental contexts, the Completely Randomized Design. These are all basically the same thing.

I am an adult, well along in my years now, and I am very glad to see that Mr. Folz takes a few moments at the beginning of his lesson to help young students deal with their very natural frustrations, arising from dealing with a complex subject, under pressure to pass and get good grades. It is hard to learn ANYTHING when you are already deep down in a well of emotional suffering and see no way out. That can be a very lonely feeling. So glad to see the instructor giving some words of encouragement. Well done on that approach and on a wonderful instructional video! Thank you!

The way Brandon Foltz introduces, motivates and teachs it's worth much respect and greafulness. Do I exagerate? Not at all: the introduction is moving, and the content is top level. I can say, I have a MSc in Economics thus I am non complete novice to statistiscs, that this is an excellent top way to spread science and knowlwdge for all the people who are willing to learn. Thank You Sir, I wish I could do something like you, obsviously on a smaller scale, for my children, my frieeds and my collegues.

Hello Brandon, I accidentally came across your tutorials while finding a solution to a real life statistical problem, and absolutely loved it. I guess, the student community and returning professionals like me, owe you a BIG THANK YOU for making statistics so easy to digest and easy to refresh. It would also be great if at the end of each lesson, you can refer to a real life worked example (perhaps an uploaded spreadsheet) to explain the application of the concept in real life. Thank you, OL
