Comment on temperature

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.
