I have an experiment with two factors MANAGEMENT and REGION. And I have three MANAGEMENT types and three REGIONS. Like this.
REGION: A, B and C
MANAGEMENT: N, P, ST
the independent variable is called PHt
I have set the aov in R in two possible ways. The first model I understand, but I do not understand how the second model set the df for each variable. I understood that the second model is the most correct for a two-way ANOVA without repetition, is that correct?:
- aov(PHt~REGION+MANAGEMENT+REGION*MANAGEMENT, data=data)
I attach the results of the two models.
