| LHS vs. HS | 1.382 | 1.404 | 0.843 |

| Some Coll. vs. College | 0.923 | 1.169 | 0.890 |
Let's take the odds ratio between less than high school and some college and between always and sometimes wrong. Calculated directly this odds ratio is:
We could have derived this from our local odds ratios by multiplication:
| Is pre-marital sex wrong? | |||
| Education | Always vs. almost | almost vs. sometimes | sometimes vs. never |
| LHS vs. HS | 0.324 | 0.340 | -0.170 |
| HS vs. Some Coll. | 0.059 | 0.225 | 0.042 |
| Some Coll. vs. College | -0.080 | 0.156 | -0.117 |
So, the log of the local odds ratio is given by:
First, lets calculate the standard deviation of the sampling distribution for the log-odds ratio:
