When defining the median for an odd number of measurements, should we use [(n+1)/2]th or [(n+1)/2]nd?

I am aware of a related question but I am nor sure if having the number 2 in the denominator makes a difference.

An educational article from the relevant Singapore Government Agency website has

' ... the (n+1)/2 -th term'

and I'm sure other texts will follow this practice (though I'd prefer the th as a superscript and without the hyphen).

This surely reflects how one would pronounce this when necessary (though I think I got away with two times per A-Level Maths cohort).

  • But if you superscript it, then it looks like you're raising 2 to the th-th power.

  • If you don't, it looks like the denominator is (2 - th) {or 2th if you omit the hyphen). The superscript is the lesser of two evils. Commented Dec 23, 2021 at 14:24
