Beginner question about correlating subsets

deca
Say I have a variable with only two values: people with education level above and below high school.

Then I have other variables lie gender, nationality, race, marital status.

Running crosstabs Chi-square tests on these only gives me the overall value for statistical significance, for example for nationality. What if I wanted to know if any specific nationality or race etc was more likely to have a HS degree or was more likely not to have one? Basically which category of a nominal variable was more likely to have a degree or not have one.

I'm sorry about the strange way my question was worded, but I suspect my problem stems at least partially from the way I'm seeing it at the moment.

Thanks!

Are you asking about how to partition an overall chi-square?  If so, maybe this will help you:

Thank you, Bruce. That is pretty much what I want to do, though admittedly I was hoping for a somewhat simpler solution. All I really want to know is which variable subsets are more associated with the dependent variable.

Thanks again for taking the time to reply!

I think that Bruce gives a solution for a bigger problem.

For your question - In order to see which cell gives the biggest
contribution to the chi-squared, you can let SPSS give you the
standardized cell deviations.  Plus or minus signs tell which direction.
