I have used a command to typeset a three- or five-number summary in LaTeX, but I can't remember the package name nor find it searching with Google or on StackExchange. Can you tell me the name of the package and/or the command?
For a three-number summary, it would, IIRC, set the lower hinge (quartile) in a small size font, the median in a bigger font, and the upper hinge in the small size font.
The package documentation also referenced an article that proposed the technique; I'm also looking for it.
@egreg: a three- or five-number summary is simply a way to show certain characteristics of a statistical distribution of a set of numbers. See https://www150.statcan.gc.ca/n1/edu/power-pouvoir/ch12/5214877-eng.htm and https://stat.ethz.ch/R-manual/R-devel/library/stats/html/fivenum.html, for example.
The contribution of this LaTeX command was to turn the five (or three) numbers into an easily-recognized object through manipulating the size of the glyphs for each number.
\newcommand{\fivenumber}[5]{\tiny#1\small#2\normalsize#3\small#4\tiny#5}seems like it might do what you want, or at least be a good start. – Teepeemm Jan 21 '20 at 23:37
