And even these two later become very interchangeable (most statistics works for interval also works for ratio variable.) So, I'd think we need not worry too much if it's ratio or interval, just acknowledging it being a continuous variables should suffice. | |

| Oct 1, 2013 at 13:55 | comment | added | Mahoni | Thank you for this very comprehensive answer to my rather vague question, it helped me a lot. Interestingly, I find nearly no references, about the scale type 'absolute'. I just found it one book: Software Metrics: A Rigorous and Practical Approach. Simply a ratio scale which is not on a fixed value range like [0,1]. My metrics that return values between 0 and 1 map continuously as they simply count fields from a set of all possible fields, hence ratio seems fine. The one with negative values: the zero does not mean complete absence, so I think it is an interval scale. | |
