I am having problems analysing baseline data for my study population.
My variables are erection dysfunction severity (mild, moderate and severe) and type of erection dysfunction (organic ED and psychogenic ED).
I want to know the percentage of mild, moderate and severe ED in both groups (organic and psychogenic) and whether the difference is significant.
Since the erection severity variable is non-dichotomous I cannot use chi square and Fisher's exact test. Please advise me which test I can use.
