To be more clear than I was -- I was referring to a design
that is basically repeated measures, Scenes (10) by Group (2);
and it needs to be analyzed with IDs specified, since IDs are not
balanced. (Presumably, each ID had several ratings.)
If your table does not reveal some coding errors, there are at
least 6 different faculty members, though there are usually only
5 ratings. You did not confirm that the same 25 students did all
25 Resident ratings. If there were a lot more raters than that,
the analysis could have difficulties from sparseness.
I think you would set this up using MIXED, specifying that IDs
are collected within Group; but I don't have the syntax.
It is certainly "legitimate" to do an analysis with small N, even
when that analysis lacks power. But 50 ratings across 5 or 6
raters is not especially "few", in the general universe of studies.

Yes -- correct -- our hypothesis is that the faculty will
consistently be significantly different (across all scenarios) than
learners.....
Can I legitimately do an "unbalanced" ANOVA with such few
faculty? Thanks --jennifer
