Students in a research methods class designed a taste-test study comparing 3 brands of coffee.  The basic design is:

                   Cup
             A      B      C
Group 1:
Group 2:
Group 3:

Thus, participants in each group tasted 3 cups of coffee and rated each on a 1-5 point scale; thus “cup” is a repeated measure.  Groups differed in the labeling and contents of the cups (basically, students were interested in whether knowledge of the brand/type of coffee alters preferences), and so “Group” is a between groups measure.  What would be the “best” way to analyze these data?  I’m drawing a blank on how to compare the relative preferences across groups.  Is there an omnibus test to do this?  I’m thinking of MANOVA, but wanted some input to be sure since multivariate analysis isn't my strong suit (actually, I’m not sure that I have a strong suit, but that’s another story).

Thanks in advance,

Fred
