Ranking: Also known as
A ranking is often known as a rank, but $\mathsf{Pr} \infty \mathsf{fWiki}$ prefers ranking as the name suggests emphasis on the process of creating the ordering upon which the ranking is assigned.
Hence on $\mathsf{Pr} \infty \mathsf{fWiki}$ the term rank in this context refers specifically to the index of a given $x \in S$ under the ranking imposed upon $S$.
Ranked data can be referred to as ordinal data, for which it is useful to compare the term ordinal variable.
