An aside, neither are ratio scales. 0 in both cases are arbitrary and a temp of 100 isn’t twice as hot as 50. Only Kelvin is like that, which makes it my favorite even if it’s never intuitive, haha
Huh, TIL. That’s actually pretty cool. Kelvin moving up the rankings 😅
Haha, I teach statistics and it’s usually a tough one walk on. You need a natural zero for ratios, even if the concept is a little weird (like 0 height). 2m is twice 1m, etc. My go to with interval (the non ratio continuous metric) tends to be likart scales. Or yelp stars, or any other arbitrary zero. I do mention temps, though
Makes sense. I always knew Kelvin started at absolute zero, but I don’t think I had ever heard of a ratio scale. I’m sure it has some kind of statistical implications about how you can analyze the data right?
Yeah, something like that. Scales of measurement is mostly a formality in undergrad but it does determine eventually what you can and can’t do with that scale.
