The point-biserial correlation is a special case of the pearson correlation coefficient that applies when one variable is dichotomous and the other is continuous. You can compute the point biserial correlation using the regular correlation syntax (e.g. CORR VAR1 WITH VAR2) in SPSS. On the other hand, if your dichotomous variable represents a continuous normal variable that has been dichotomized (e.g., high and low anxiety), then what you want to compute is the biserial correlation. This is not quite the same as the point-biserial. To compute the biserial correlation, you can use an SPSS Macro is available from the following site.

I am looking to quantify the relationship between some continuous variables and a dichotomous variable. I was simply looking to run correlations. Is this possible in SPSS and how would I go about doing it? I have both SPSS 13 and 14. Many thanks, Brock ```
