Q: Inter-subject Reliability

Hi all

Summary: Can r be used as a parametric variable?

I have a bit of a problem in my research and I was wondering if any
could help.

The problem is:
12 Subjects rated 20 items on 2 different scales. I believe that on one
of these scales subjects will agree in general on what ratings to give
and on the other there will be more variability between subjects'
patterns.

To get a measure of subject agreement I have correlated each subject's
scores with each other subject's score on that scale. This give me two
set of r values one of 0.09 and one of 0.01. I want to know if a t test
on these r values would be a legitimate test to conduct to see if there
is significantly greater agreement between subjects and one scale than
on the other. If so does this test have a particular name?

If the procedure is not appropriate then can anyone suggest a test that
can compare inter subject reliability.

I would prefer if replies are e-mailed and I will post a summary of
replies if I receive them

Thanks

Michael Lewis
