Nowadays, SPSS versions have a test t for differences in contingency tables
(personalized tables module) with Chi Square and T test . Use of A / B /C
(for identify groups) ... is more general in other software like SPSS,
BARBWIN, QUANTUM and other.

I hope PSPP with this feature early.

Thanks.


Un cordial saludo.
