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. -Alan On 9/15/2015 3:20 PM, Trisha Carr wrote: > Hi, > > I have a PSPP question and any help at all would be much appreciated! > I have a data set with a likelihood to recommend rating and > performance on attribute ratings for multiple companies.
