In statistics, the odds ratio[1][2][3] (usually abbreviated ″OR″) is one of three main ways to quantify how strongly the presence or absence of property A is associated with the presence or absence of property B in a given population. If each individual in a population either does or does not have a property ″A,″ (e.g. "high blood pressure″), and also either does or does not have a property ″B″ (e.g. ″moderate alcohol consumption″) where both properties are appropriately defined, then a ratio can be formed which quantitatively describes the association between the presence/absence of "A" (high blood pressure) and the presence/absence of "B" (moderate alcohol consumption) for individuals in the population. This ratio is the odds ratio (OR) and can be computed following these steps:
