I have a set of data in which the response variable is continuous and the other independent variables are dichotomous (not naturally occurring).

I think I have to perform Biserial correlation (I an aware of the difference between point biserial and biserial correlation).

How can I do this on SPSS or any other statistical software?

    $\begingroup$ If you have a dependent and an independent variable, then why not use regression? $\endgroup$ – Peter Flom Feb 10 '13 at 14:38

If you are looking for "Point-Biserial" correlation coefficient, just find the Pearson correlation coefficient. In SPSS, click Analyze -> Correlate -> Bivariate. The rest is pretty easy to follow. Computationally the point biserial correlation and the Pearson correlation are the same.

  • $\begingroup$ I stand corrected. What I meant was the "Point-Bieserial" correlation coefficient. $\endgroup$ – user765195 Feb 10 '13 at 17:50
