Module 13: F-Distribution and One-Way ANOVA
Relationships Within an ANOVA Table
Above is a basic ANOVA table. How are the cells in this table related? Let’s look at the first two columns of data S.S. and d.f. :
Notice how the first two cells add up to the total below it in the columns highlighted above. (i.e. 5272.015 + 5763 = 11035.015)
Now let’s move onto the third column M.S. . In this case, we need to look at the rows which the cells belong to:
Notice how the values in the third column are the quotient of the prior two cells (i.e. 5272.015 ÷ 5 = 1054.403)
This leaves us with our last column F.
This again is a division problem. (i.e. 1054.403 ÷ 113 = 9.331)
The relationships work for every ANOVA table. However, you may not be given the same elements as you are in this table. In this case, you may have to work backwards and solve for the other missing cells.
