What are the significant columns in ANOVA table?
There are one or two ways to show the ANOVA table, depending on the various factors. The significant columns in the ANOVA table are as follows: 1. “Source” – It means the source which is responsible for the variation in the data. 2. “DF” – degree of freedom of the data.
Which is the key table in interpreting ANOVA?
INTERPRETING THE ONE-WAY ANOVA PAGE 2. The third table from the ANOVA output, (ANOVA) is the key table because it shows whether the overall F ratio for the ANOVA is significant. Note that our F ratio (6.414) is significant (p = .001) at the .05 alpha level.
