Dear listers,
I am trying to pull desciptive statistics from a large observational study.
Almost all of the variables are categroical by their nature or recoded as
categorical. I am looking for the demographics for this population in 3
different time period, so the table would be PERIOD*VAR in RxC format(not a
2x2 table). The sample size of sub-population in each time period is great
than 10,000. So almost every variable I tested are significantly different
overall. As I see more and more Prob <.0001, my excitement fated away. Am I
using a right method? What I did is simple PROC FREQ with request of
Chi-Square test.
PROC FREQ data=large;
tables PERIOD*ETHNGRP/Chisq;
run;
Any comments or suggestions?
Thanks,
Sophia
