Subject: Comparing two chi-square tables
Content-Type: text/plain; charset=us-ascii
The following is a reposting of a question I posted before the Labor
Day weekend and received no responses. Hoping for a better response now
that we're all back to work.
I have two chi-square tables that represent data from seperate years,
1997 and 1998. Each table consists of 2 categorical ordinal variables
Performance Evaluation (5 levels) and Seniority (4 levels). Both are
(p <0.05). I know that the size of the Chi-square is directly
proportional to the sample size so they should not be compared to one
another. But I want to ask if they are different from one another. Are
the two years are significantly different with respect to the
relationship between Performance Evaluation and Senoirity. I could do a
logistic regression with year as my dependent variable but it seems
there shouold be an easier and more straightforward way of answering
this question. Any help would be appreciated. Thanks.
