Statistics 101: One-way ANOVA, Understanding the Calculation

So this is the next video in our series about the analysis of variance, or ANOVA. In Part 2 we go into Microsoft Excel and "hand calculate" a One-way ANOVA. We then compare our result to the SPSS output and Excel's own ANOVA tool.
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.
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.

My professor should pay you to tutor him to teach him how to teach

@rggary2286 4 года назад

My class should find their way to this video and learn ANOVA so that I do not have to come and learn how to teach. :)

Thanks a lot. More power!

@nadolsw 9 лет назад

While a bit slowly paced, these videos are great! Too many teachers gloss over the nuts and bolts of statistical analysis and test only on whether or not students can identify whether p is less than 0.05.

@sanjayshende5632 8 лет назад

Brandon, I have to adulate you profusely for the quality of your teachings and the valuable material you offer. I have 2 quick questions: 1) I got why you multiplied by 2 (3-1) in SSC but not why you multiplied by 7. 2) Can you explain why is that dferror = N-C? Thanks.
