I have have a dataset of about 500k subjects, each subject have 2 measures of the same thing:
measures A: in which 0 is the worst case and 1 is the best case.
measures B: in witch ordinal variable with values 0,1,2,3 in which 0 is the worst case and 4 is the best case.
I want check if the two measures are consistent witch each other, is there statistical procedure to do it?
Edit: by consistent I mean that people that are in the best case in the measure A tend to have higher values in the measure B, And people in the worst case in the measure A tend to have lower values in the measure B.
