single and multiple nominal


Less is more. Stay pure. Stay poor.
This seems a little like homework, so I will start by asking what is a nominal variable? Categorical? So, what do you think the answer might be?
it is not HW at all>>I'm doing a research by using non linear canonical correlation analysis, and for that I used SPSS software. when I stated the application at appeared to me the issue of single and multiple nominal scale which made me really confused!!
I need a simple explanation for them please
