The point biserial correlation coefficient is a special case of Pearsons correlation coefficient. For testing the correlation between categorical variables, you can use: binomial test: A one sample binomial test allows us to test whether the proportion of successes on a two-level categorical dependent variable significantly differs from a hypothesized value.For example, using the hsb2 data file, say we wish to test whether the proportion of females (female) differs significantly from 50% . Notes: (a) This test of homogeneity of variances is mathematically identical to a test of indepencence of v/non-v and your categories--even though the phrasing of the interpretation of results may be different. Thus, we know the regression coefficient for females is 0.420 (p-value < 0.001). Creating an SPSS chart template for it can do some real magic here but this is beyond our scope now.
