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. I'm interested in calculating the correlation for
likelihood to recommend and performance on the attributes. I
know how to use PSPP to calculate this correlation for each
brand individually.
My question is, how can I calculate the correlation for
likelihood to recommend and performance on attributes for
all companies as a whole? Thanks in advance for any and all
help.
