I have an overall sample of 5000+ from 40+ different towns and 6
different grades. One person wants to look at a subsample of 200 from
specific towns and grades and compare this subsample with the rest of
the group on outcome variables.
Advice appreciated here.
The only demographics are self-reported family structure and
maternal/paternal education. Ideas: 1) I could try to match the
demographics/grades of the selected 200 with 200/5000 other subjects.
2) I could randomly select 200/5000 other subjects and test to see if
there is a sign difference in the demographics. 3)??
4)?? Outcome variables are all categorical--assuming
chi-squares testing here. Suggestions welcomed. Thanks!
