What's the difference between Cardinal Utility and Ordinal Utility?
 
btw I'm not looking for anything in depth... you can guess it from the name of the two things. A sentence will do.
 
Cardinal utility is saying utility can be measured absolutely, ordinal says it can be done relatively (difference curve stuff).

That is, if I remember correctly from econ.
 
Are these economics terms?
Yup.

Pretty much.

You could guess it from the names cos "cardinal" means 1, 2, 3, 4, 5 etc, whereas "ordinal" means 1st, 2nd, 3rd, 4th, 5th etc.

Ordinal, therefore, sez you can rank the utility of several different things, but not put an actual value on them. So you can say, "I prefer Mars bars to Twix", but not "I like Mars bars 2.4 times more than I like Twix".

Cardinal, OTOH, sez that you can say that, although a "cardinalist" would offer a less ridiculous example, e.g. "I'd rather have 50p than a Twix, but I'd rather have a Twix than 51p, therefore a Twix is worth 50p". We make these decisions all the time, even if we don't know it.

LighFang's up!
 
Something about football? Perhaps about the rules of the game?
