response variable. Example 1: Let’s use odds ratio to find out! Step 1: the oddsof a student drinking beer is 90 to 10 or 9/1 and the odds of a teacher drinking beer is 20 to 80 or 1/4 = 0.25:1. Step 2: the probability of success for every cell is. π. 11 = n11/n 1+ = 90/100 = 0.9. π. 12 = n12/n 1+ = 10/100 = 0.1. π. 21 = n21/n 2+ = 20/100 = 0.2. π.
