Hi Everyone,

I have a random question related to odds and percentage that I can't figure out. Does this statement in terms of the percentage difference sound true? "The odds for students in group A to graduate are 5.03 (11,734 group A students graduate and 2330 do not) and the odds for group B students to graduate are 4.33 (3222 group B students graduate and 743 do not). Thus, the odds for for graduating for group A students are 16% higher than the odds for group B students."

Are the odds really 16% higher. I can not wrap my head around this to determine how it is a 16% difference however I suspect the statement is true.

Thanks so much for any help or assistance.

Hello and thank you!!! I have been reading on the odds ration formula and can not find any explanation on how to get it two work for my problem. Specifically how the odds for group b are 16 percent higher. Is there a calculator that anyone know's of to plug in the numbers and get the percentage or something along those lines.

Thanks again!

$$\frac{5.03-4.33}{4.33}\approx 0.16$$
