Hi,
Anova compare the means of more than two groups, in your case anova test
H0 hypothisis
H0: means(control)=mean(tread1)=mean(tread2)=mean(tread3), if there is
at least one différence,
you can identify the mean difference between groups by using post hoc
test to testing your B suggestion.
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
3 matches
