Trisha,

I agree with Frank, I'm not able to visualize your dataset.  You might
be interested in an ICC but I'm not sure (or sure of which one) and I
don't think that PSPP does that calculation (it's an option in
RELIABILITIES in SPSS).

So, if you have several correlations, I recommend that you compute them
using PSPP and combine them meta-analytically.  The simplest
accumulation would be to take the weighted average (if each company has
the same sample size, then just the average).  A more interesting
question would be whether the correlations are homogeneous or if there
are moderators.  Neither PSPP nor SPSS is particularly well suited for
these kinds of (meta-analytic) calculations.
