Abstract
The odds ratio test is just like the chi-square test applicable for testing cross-tabs. The advantage of the odds ratio test is, that an odds ratio value can be calculated. The odds ratio value is, just like the relative risk, an estimate of the chance of having had an event in group 1 as compared to that of having had it in group 2. An odds ratio value of 1.000 indicates no difference between the two groups. This chapter gives examples of odds ratio analyses. The odds ratio test is, like the z-test (Chap. 36), and the chi-square test (Chap. 38) applicable for testing cross-tabs. A nice thing about odds ratio tests is that, unlike the other tests, they provide odds ratios, that can be interpreted as relative risks.
