I have numbers (arranged in a 2x2 contingency table - smokers/nonsmokers,
respiratory disease/no disease) for our study population (of about 1,000).
I also have numbers (arranged the same way) for the general U.S. population
(from the U.S. Office of Smoking and Health).
Is there a statistical test that allows me to compare both populations (i.e.
a test that compares the chi-square value from each population)?
Is there a statistical test that assesses if our study population is biased
(compared to the U.S. population) and if it is biased, associates some type
of value to this bias?
Any help will be greatly appreciated. Thank.
