I have a population in which I am looking at two variables in individuals.
The first is the size of their vertebrae, the other is the presence of pathology in the teeth. The first is in mm (ranging from 9 mm to 15 mm) and ranges over 8 vertebrae, the other is binary (present and not present (and missing)) and ranges over 6 teeth.
Now, what I want to know is if there is a relation with small, or big, vertebrae and the presence of pathology in the teeth. Which statistical test/procedure is suitable?
