Quantified

Quantified is the past participle and an adjective form of the verb quantify. To quantify is to determine or express the quantity of something using numbers or measurements. When something is described as quantified, it has been measured or expressed numerically, often implying a degree of precision or standardization beyond qualitative description.

Origin and related terms: quantify derives from Latin quantus "how much" through medieval and modern French into English; the noun quantity refers to a measured amount, and quantification is the process of expressing something in numerical terms. In formal logic and linguistics, "quantified" describes statements that employ quantifiers such as universal (for all) and existential (there exists) to indicate scope over a domain.

Applications: quantification is central to science, statistics, and data analysis, enabling comparison, modeling, and uncertainty assessment. It underpins risk assessment, quality control, and decision making. The phrase "quantified self" refers to individuals who measure personal data (such as steps, sleep, or glucose) to inform behavior. In research reporting, quantified results reported with units and uncertainty are preferred for reproducibility.
