Art & Jim have responded to points 1-3. (Art meant to say

correlation between a dichotomous *variable*, not a

dichotomous correlation.)

You mean the binary variable is an outome (or dependent)

variable? How about logistic regression then?

The SPSS output will have in a table of regression

coefficients a column headed EXP(B). This will give you the

odds ratio associated with a one-unit increase in your

continuous variable. (For some variables it you'll want to

change the scaling so you get the odds ratio associated a

change larger than one unit. E.g., for age, you might want

the OR for a 5- or 10-year change.)

For help with logistic regression in SPSS, see the textbook

examples here:
