I'm running an OLS regression in SPSS and have a question about models that feature both Scale and Nominal/Ordinal variables. I say nominal/ordinal because the variables I'm looking at range from 0-2, with 0 representing a restricted worker's rights condition, 1 a somewhat restricted condition, and 2 an unrestricted condition. So I feel since it has a logical progression from least to most freedom, that it could well be ordinal. Does such a variable require recoding if I included it in a model that also features scale variables? My DV is also scale.
