b. Using methods presented in this chapter, describe the strength of the association.         

4. Discuss an example that would benefit from using the odds ratio to compare two groups. Be sure to discuss what the comparison groups are and why the odds ratio is helpful.

For binary response variable, we use success to denote the outcome of interest and failure to denote the other outcome. The odds of success are defined to be:

Odds = Probability of success/Probability of failure

The odds ratio is a measure of association for 2x2 contingency tables that equals the odds in row 1 divided by the odds in row 2. In other words, it is a relative measure of effect, which allows comparison of the intervention group of a study relative to the placebo/control group.
