One Way Analysis of Variance is easier than it looks, but there are A LOT of calculations to perform! If you start by summarizing each sample into a few statistics, the process is much easier to handle.
In some questions, the data from the different samples has already been summarized into numerical statistics. If so, then this is where you would start your solution.
In other questions, you won't have access to any of the raw data, but instead you'll be expected to fill-in-the-blanks on a partially completed ANOVA output. Here's how!
Test your understanding of Chapter 14: Analysis of Variance. Each question is accompanied by a mini-video lecture showing you how I decided which solution was the correct one.
