After getting significant results on your 2 x K chi-square, you are
likely to want to compare, across the K categories, differences in p, where p
is the ratio of outcome1 to n. An easy way to do this is to use the calculator
at Vassar to find confidence intervals for the difference between pi and pj .
A less convenient way to do this is to conduct a series of 2 x 2 chi-square
analyses.

Subject: [tips] Statistics question
I need some guidance on analyses when you have a categorical predictor variable
and a dichotomous criterion.
I would be happy to watch some recommended tutorial videos if someone can
please recommend some for me. My google search and you tube searches seemed to
all combine a continuous variable at one end or the other.
Alternatively a good read would be equally good.
Thanks.
