Tölfræðilegrar
Tölfræðilegrar is the genitive singular feminine inflection of the Icelandic adjective tölfræðilegur, meaning "statistical" or "pertaining to statistics." The adjective is formed from the noun tölfræði (statistics) with the common suffix -ilegur, which yields a word meaning "relating to" or "characteristic of." In Icelandic, adjectives agree with the noun they modify in gender, number, and case, so tölfræðilegur has several inflected forms. The genitive singular feminine form is tölfræðilegrar. It is used with feminine nouns in the genitive case, for example tölfræðilegrar aðferðar ("of a statistical method") or tölfræðilegrar rannsóknar ("of a statistical study").
The term appears in academic, scientific, and policy writing to describe data-driven content, analyses, and conclusions.
