quick ANOVA question
Hello,
imagine the following experimental design:
Group - Value
control - 5
control - 6
control - 5
treated1 - 8
treated1 - 9
treated1 - 9
treated2 - 15
treated2 - 16
treated2 - 15
treated3 - 25
treated3 - 30
treated3 - 28
What I like to know is if I apply an ANOVA to this data and choose the
control group as the reference group (using the relevel function)
what groups exactly are compared? Are only all treated groups 1, 2, 3 tested
agains...
