Dear all,
Just a quick question (I hope).
Say we have "a" groups and the (omnibus) ANOVA test is significant. Subsequently, Dunnett's (multiple comparison) test is " typically is used whenever one group (most
commonly the control group) is compared to all the other a-1 groups (most commonly the
experimental groups)". Now, say, if my groups were, instead, age category:
˜20-25 years
26-30 years
31-35 years
36-40 years
41-45 years
Could we still use Dunnett's test to compare each of the younger age categories to the 41-45 age category?
Many thanks for your views on this issue, in advance.
Kind Regards,
Kim
