100 : Percentile :: 9 : ?
There doesn't appear to be a common term for the 9-quantile. What are your thoughts on this analogy? Am I on the right track? If it said 8 or 10 I would answer octile or decile, respectively, but I'm not sure since it's 9.

I am not really a math person, so you might get better help from other people.
What this looks like to me is an association like you would see on an IQ test.
sky is to blue as apple is to X. Something like that.
There's just something slightly unsatisfying about that answer. I feel like nonile is more of a neologism than is warranted by the question and that a more succinct answer is out there.
Maybe the question is just flawed. Why would someone pick the one single-digit quantile without an official name? The answer is definitely related to statistics but beyond that I'm stumped.
- The only 2-quantile is called the median
- The 3-quantiles are called tertiles or terciles → T
- The 4-quantiles are called quartiles → Q; the difference between upper and lower quartiles is also called the interquartile range, midspread or middle fifty → IQR = Q_{3} − Q_{1}
- The 5-quantiles are called quintiles → QU
- The 6-quantiles are called sextiles → S
- The 7-quantiles are called septiles
- The 8-quantiles are called octiles → O
- The 10-quantiles are called deciles → D
- The 12-quantiles are called duo-deciles → Dd
- The 16-quantiles are called hexadeciles → H
- The 20-quantiles are called ventiles or vigintiles→ V
- The 33-quantiles are called trigintatreciles → TT
- The 100-quantiles are called percentiles → P
- The 1000-quantiles are called permilles → Pr
Why can't you answer my question??? You consider it legitimate; but on what grounds? Maybe if we knew where it comes from (or at least what sort of source it comes from) we could help you make that judgment. Maybe it comes from a country where the word "nonile" is used; or maybe there is reason to think they are just trying to confuse you. Or maybe you're just trying to mess us up?
It's online? Give us the link! Or if the same page has stuff on it that we would object to, give us a screen shot of the relevant part.
I agree that it's odd; we're just trying to figure out why.
