I am completely new to SPSS and I have to split the mean by one variable or even by two variables ("produce a single table showing the mean of the symptom severity checklist score before and after treatment, split by anxiety disorder and by patient gender")

This is just the example I have been given, but it could of course be anything where i need to split the mean by two variables and have only a single table.

I couldn't really find anything about splitting the mean by one (or, even worse, by two variables) in my book or the internet, and I tried it but got two tables. Does anyone know how to do it in SPSS?

Thank you
