How would I go about using SPSS to bulk-compare variables to demographics, with the goal of finding variables that are statistically significant (P-value and/or correlation) only for certain subsets of demographics?
For example, say I had variables A, B, C and demographics X, Y, Z, how would I prove that A is relevant to X and Y but not Z, B is relevant to Y only, and C is relevant to X+Z together but not individually, etc?
In theory this could be done by running a linear regression report on each dependent variable then comparing the results, and that's fine with only three, but I have over 100 variables and ten sets of demographic questions each with up to ten possible responses, so I really don't want to do this manually if there's any other way?
I suspect part of the method will involve recategorising some of my inputs from scalar to ordinal, but what comes after that?
