Question
46.The odds ratio is which of the following? A. The ratio of the odds after a unit change in the predictor to the original odds B. The probability of an event occurring C. The ratio of the probability of an event not happening to the probability of the event happening. D. The ratio of the probability of an event happening to the probability of the event not happening.
Solution
The correct answer is A. The odds ratio is the ratio of the odds after a unit change in the predictor to the original odds. This is a statistical term used in logistic regression to show the strength of the association between a predictor (independent variable) and the outcome (dependent variable). It tells us how much the odds of the outcome increase (or decrease) with a one-unit increase in the predictor.
