I have two variables I want to test with correlation, one is continuous and the other dichotomous. My data are non-normally distributed, plus the variance is heterogeneous, so I have to apply a non-parametric test of correlation. The problem is, I don't know of any test that fits my requirements.
Spearman's correlation coefficient requires ordinal data for both variables.
Point-biserial correlation coefficient fits my data type, but it's a parametric test.
I'm unaware if there's some test else out there. What should I do?
