Statistics 101: Two-way ANOVA with Replication, Interactions

This is the next video in our series about the analysis of variance, or ANOVA.; more specifically, the Two-Way ANOVA with Replication. This is also called a Two-Factor ANOVA. To make the topic more manageable, I have divided this video into several parts. In Part 2A, we will cover the basics of the 2-way ANOVA interaction. In Part 2B we will discuss the graph of marginal means. These are sometimes called "interaction graphs" even though no interaction may be present.
So in our last video, we took an in-depth look at the basics of the Two-Way ANOVA. As with many visual tools, marginal means graphs allow us to visualize the characteristics of each factor and any interaction that may be occurring between them. We will learn how to construct and interpret marginal means graphs and then compare the graph to the actual output from, in this case, SPSS.
This video offers a solid, comprehensive, conceptual foundation of Two-Way ANOVA and interactions using an example problem with illustrations and graphics. So 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.
