tölfræðilegu

Tölfræðilegu is Icelandic for the adjective meaning statistical. It derives from the noun tölfræði, which denotes the field of statistics. The form is used to describe aspects that pertain to statistics, such as data, analyses, methods, or conclusions that rely on statistical reasoning.

In practice, tölfræðilegu appears in academic and professional discourse to indicate that something is based on statistical principles or data. It is commonly attached to nouns referring to data or procedures, for example in phrases describing statistical data, statistical methods, or statistical results. The term signals that the item being described is analyzed, interpreted, or presented within a statistical framework rather than in purely qualitative terms.

The concept sits within the broader discipline of statistics, which includes descriptive statistics, inferential statistics, probability theory, sampling, estimation, hypothesis testing, and data visualization. Tölfræðilegu approaches emphasize the collection, organization, and interpretation of numerical data to draw inferences about populations or processes. The adverbial form tölfræðilega is used when describing actions or outcomes in a statistically oriented manner, such as reporting statistically significant findings or presenting data statistically.

In Icelandic usage, tölfræðilegu functions as a descriptive modifier and aligns with general grammatical rules for adjectives, changing form to agree with gender, number, and case of the noun it describes. See also tölfræði.
