Statistics 101: One-way ANOVA, Understanding the Calculation

Рет қаралды 302,739

Күн бұрын

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.

thank you so much for all the videos. I've been studying statistics with your videos for quite some time. They are all very clearly explained. But for this one, I really don't understand why we have to multiply column variance with 7 to get the SSC. SSC is the sum of squares of the difference between column mean and overall mean, right? not between each observation point and overall mean(which is SST). Thank you in advance for your clarification.

@user-ci1xv2jn1l 4 жыл бұрын

Thank you for you prompt reply. In previous videos, you said SSC is the sum of squares of differences between column mean and overall mean, which sounds pretty reasonable. But in this one, you multiplied column sum squares with 7 to arrive at SSC? Could you please clarify?

@@BrandonFoltz That part in this video(SSC=VAR.S(A2:C2)*2*7) is from around 17:50 to 18:00. You actually explained where the "7" is from. It's the 7 observation points in each column. But I don't get it why we have to do it 7 times. Thanks.
