Use and Interpret Unadjusted Odds Ratio in SPSS Accredited Professional Statistician For Hire
An odds ratio is a relative measure of effect, which allows the comparison of the intervention group of a study relative to the comparison or placebo group. So when researchers calculate an odds ratio they do it like this: The numerator is the odds in the intervention arm The denominator is the odds in the control or placebo arm = Odds Ratio (OR)

Moreover, in SPSS Statistics, deciphering these values correctly can be confusing as the variable arrangement and category order affect the calculation of the ratios and their interpretation.
How to Compute an Odds Ratio Using SPSS YouTube
Introduction Let's begin with probability. Let's say that the probability of success is .8, thus p = .8 Then the probability of failure is q = 1 - p = .2 The odds of success are defined as odds (success) = p/q = .8/.2 = 4, that is, the odds of success are 4 to 1. The odds of failure would be odds (failure) = q/p = .2/.8 = .25.

The odds ratio for a feature is a ratio of the odds of a bike trip exceeding 20 minutes in condition 1 compared with the odds of a bike trip exceeding 20 minutes in condition 2. Positive odds ratios indicate that the event is more likely to occur, whilst negative odd ratios indicate the event is less likely to occur.
