Not if some students only get hard graders and some only get easy
graders.
If all students got all graders an equal amount of time it probably
won't matter at all.

Ben,
The other posters give some good advice, but you could also set
simultaneous confidence intervals for all 7 categories.
If you are trying to establish "equivalence" then you could define
some range that would be appropriate (say, within 3%). The CI's are
easy enough to compute and I think a

You should be able to find tons of examples of GEE's, but maybe not

I wrote a paper a few years back (when I was convinced GEE's would

simple pretest-posttest design. I remember one r

A naive solution seems reasonable if I am willing to assume that students are
randomly assigned to the preceptors for evaluation. If so, I'd expect the
average rating given by each judge to be the same. So, force the judges'
means to be be equal to the overall mean by dividing each individual sco
