Which of the following estimates of an odds ratio most strongly suggests a computational error? 1) 7.8 2) 1.2 3) -0.9 4) 20.9 correct answer: 3) -0.9 An odds ratio of -0.9 most strongly indicates a computational error because an odds ratio is calculated using probabilities, which cannot be negative. An odds ratio is the probability that an event will occur divided by the probability that it will not occur. Since probabilities cannot be negative, a negative odds ratio would indicate compu...
