A> Use of the statistical notions presuppose that there are statistics to cover the case (at least informal one), so we can assume whatever is needed to make this meaningful. In this case, some sort of ordering. The {sepo'i} is a good idea — or something to indicate the property involved (with an implicit ordering, e.g, salary by amount, height by height, and so on).

B> I agree that mode is trickier, since — for one thing — there can be more than one mode in a set. So the idea of a predicate only is useful ({le} then could select one for consideration or the lot of them, depending). But again, the fact that there are the statistics will simplify out the cases: the Chinese example is not, apparently, a mode but simply the most frequent value.

A>{midju} works for naturally ordered sets:

li re cu midju li pa ce li re ce li ci
2 is in the middle (is the median) of set {1,2,3}.

But for unordered sets it is less clear:

la djan cu midju lo'i prenu
John is in the middle of the set of persons.

Without an ordering for the set of persons, the above does not
seem to make sense. I guess {midju} centrally refers to spatial
position, but even then for people distributed over the surface
of the globe that is not much help.

We could use {midju} with an added {sepo'i} term:

la djan cu midju lo'i prenu sepo'i lo ka ce'u nanca makau
John is the median of the set of persons when ordered by
how old they are.

B>The mode makes sense for sets that can have repeated members.
The mode of {1,3,4,4,4} is 4. Maybe we could use {rapraicmi},
"x1 is the most repeated member of x2" for this:

li vo cu rapraicmi li pa ce li ci ce li vo ce li vo ce li vo
4 is the mode (most repeated member) of {1,3,4,4,4}.

{fadni} would be closer to something like: "x1 is a member of
x3 whose value by x2 is the mode", but I think it has to be a
very significant mode for fadni to work. For example, Chinese
people are the ones who have the modal value of nationality
among humans, but I'm not sure I would want to say that
all Chinese and only the Chinese are fadni in nationality.
Perhaps a relativised {fadrai}, "most typical", would work.
