Instead of thinking "I perfectly measured his skill level; it's 14", think "I obtained X bits of evidence that his skill is between 13 and 15".

Um - I'm not sure how this relates to what I said... can you please expand/clarify? :)

What I mean is: once you learn the colour, you can reason backwards that "oh, given we have X people with a skill roughly between 13 and 15... 90% of them are blue... this must imply that in the general population, blue weasels are more likely than red weasels to score roughly between 13 and 15 on skill tests at a ratio of roughly 9 to 1"

I don't know that you can prove much else base don just that data alone.
