Explaining Odds Ratio's - simply


Fortran must die
I am showing to a smart, but not technically inclined, audience Odds Ratio. I am comparing one variable's Odd Ratio to another in the process. If there is a simple way to show/explain what the odd ratio is I would love to know it. I have worked a long time looking for one....

For example if a dummy variable (nearly all are variables are dummy although a few are days and some spending in dollars) has an odds ratio of 1.4 and another 1.9 what does that actually mean and how could you compare them.
