Hi everyone. I'm pretty new to statistics so sorry for the dummy question 
I need some nonparametric statistics to correlate a binary variable with a continuous one. Binary variable is yes or no.
For instance:
- one variable is a blood test score (ranging from 0 to 100);
- the other variable is to say if a patient suffer from a specific disease, so it's a yes or no variable.
I want to find out if high test scores correlate with the fact of having a certain disease.
I have to use nonparametric statistics.
Is there any way I can use Spearman's correlation to do this?
Is it ok to use 1 = yes and 0 = no, so as to have a sort of rank?
Yes/no looks like something nominal and I know variables should be at least ordinal in a Spearman's Correlation.
Thanks a lot for your help!
