Statistical methods vary according to the measurement levels of variables, and it can make a difference if variables are classified as nominal, ordinal, or interval/ratio. But I've never seen any statistical test that depends on the interval/ratio distinction.

Leaving aside for the moment any philosophical objections to the "standard" classification of measurement levels, is there any statistical reason to care about the difference between interval and ratio measurement levels?

Does the interval/ratio distinction ever matter?
