representatively

This adverb is primarily used in technical, academic, or legal registers. It describes the method by which a small part of something is used to stand for the whole, ensuring that the characteristics of the larger group are accurately mirrored in the sample. In statistical contexts, it emphasizes the lack of bias in selection.

In legal or administrative contexts, the term shifts toward the concept of agency or proxy. It describes an action performed not for the individual acting, but as a formal substitute for another party. This distinguishes it from acting "personally" or "individually."
