Statistics 101: Two-way ANOVA w/o Replication, A Visual Guide

This is the next video in our series about the analysis of variance, or ANOVA.; more specifically the Two-Way ANOVA. To make the topic more manageable, I have divided this video into two parts. In Part 1 we will discuss the conceptual background using graphics and charts and then in Part 2 we will go into Microsoft Excel to conduct a "hand" calculation of a Two-Way ANOVA and also solve our example using Excel's built-in data analysis tools.
There are several types of ANOVAs. In this video, we will be focusing on the Two-Way ANOVA which itself comes in two flavors; without replication and with replication. In this video, we will be learning about the Two-Way ANOVA without replication; also known as the completely randomized block design.
If you are new to ANOVA or are still trying to figure out exactly what it is...this video is for you. So sit back, relax, and let's go ahead and get to work.

You've made the concepts easy to understand! Please continue to make more videos on, e.g. neural networks, machine learning, decision tree, cluster analysis, factor analysis etc.

  • @BrandonFoltz

    Blocking doesn't "eliminate" row variance per se; it accounts for it. The total variance is split up into column/group variance, row/block variance and then what ever is left is error variance. If the error variance is small, then most of the overall variance is in the columns and/or blocks; which is another way of saying, that is where there are differences in the means.

    I have always struggled with statistics... BUT your videos prepared me the night before my PhD comprehensive exam... Which is right now... You are soo good, that I took the time to make this comment even though tomorrow morning is the real deal.... And many of yous will be like "heyyy, he's a PhD and doesn't know the foundation of stats??!!". And I'm like "Yoooo, it is my weakness and I scratched by up to this point without knowing the depths". Then yous will maybe say "Broooo that's not good man". Then I will emphasize "Yeeeaaa maaaan, it's bad, and that's why I came here, and gosh-darned it was effective thanks to Brandon Foltz".
