- TL;DR Summary
- Understanding when ok to treat ordinal variables treated as interval variables

Hello,

Ordinal variables (see Likert scale) can be labelled using numbers and ranked by those numbers. However, the difference between category 2 and category 3 may not be exactly be the same as the difference between category 4 and 5. That said, I noticed that in social science ordinal variables are sometimes approximately treated as if they were numerical predictors if the ordinal variable has many levels...Is that a correct approach? What justifies that? I did some reading and found a variety of opinions on the topic...

Thanks
