Values that divide sorted data into equal subsets other than four have different names.
*The only 2-quantile is called the [[median]]
*The 3-quantiles are called [[wikt:tertile|tertile]]s or [[wikt:tercile|tercile]]s → T
*The 4-quantiles are called [[quartile]]s → Q; the difference between upper and lower quartiles is also called the [[interquartile range]], '''midspread''' or '''middle fifty''' → IQR = {{math|''Q''<sub>3</sub> − ''Q''<sub>1</sub>}}.
*The 5-quantiles are called [[wikt:quintile|quintile]]s or [[wikt:pentile|pentile]]s → QU
*The 6-quantiles are called [[wikt:sextile|sextile]]s → S
*The 7-quantiles are called [[wikt:septile|septile]]s → SP
*The 8-quantiles are called [[wikt:octile|octile]]s → O
*The 10-quantiles are called [[decile]]s → D
*The 12-quantiles are called duo-deciles or dodeciles → DD
*The 16-quantiles are called [[wikt:hexadecile|hexadecile]]s → H
*The 20-quantiles are called [[wikt:ventile|ventile]]s, [[wikt:vigintile|vigintile]]s, or demi-deciles → V
*The 100-quantiles are called [[percentile]]s or centiles → P
*{{anchor|millile}}{{anchor|permille}} The 1000-quantiles have been called permilles or milliles, but these are rare and largely obsolete<ref name="walker">{{Cite book |last1=Walker |first1=Helen Mary |url=https://books.google.com/books?id=ogYnAQAAIAAJ&q=permille |title=Elementary Statistical Methods |last2=Lev |first2=Joseph |date=1969 |publisher=Holt, Rinehart and Winston |isbn=978-0-03-081130-2 |language=en}}</ref>
