Hi Bob,
You need to create a datafile with three columns containing your two "categorical variables" and a "count variable". Consider the 2x2 table on gender and opinion:
Opinion
Agree Disagree
Male 10 20
Female 30 40
Your three-column datafile should be:
Gender opinion count
Male agree 10
Male disagree 20
female agree 30
female disagree 40
Then run the syntax:
WEIGHT
BY count .
CROSSTABS
/TABLES=gender BY opinion
/FORMAT= AVALUE TABLES
/STATISTIC=CHISQ CC PHI
/CELLS= COUNT
/COUNT ROUND CELL .

I seem to recall that someone wrote that SPSS can calculate all chi-square
statistics from a contingency table as input. But I can't find that
message. I've also checked the syntax command manual, without success.
Would someone please point me in the right direction?
Thanks,
Bob
