variabilné

Variabilní is a Czech adjective that describes something capable of varying or subject to variation. It is derived from Latin variabilis, meaning changeable. The noun form variabilita denotes the quality or extent of variation, while variabilně can function as an adverb describing how something varies. In everyday language, variabilní can describe anything whose value or state is not fixed and may change under different conditions.

In mathematics and statistics, variabilní is used to characterize data, parameters, or models that may take different values. The more common Czech term for a quantity that can assume different values is proměnná (variable), but variabilní is often employed to describe properties of a dataset or system that exhibit variation. For example, variabilní data or variabilní rozptyl refer to data or spread that reflect variability, while sources of variability include natural variation and measurement error, both influencing uncertainty in analyses.

In science, engineering, and economics, variabilní describes processes, rates, costs, or qualities that change with conditions, time, or context. Examples include variabilní sazba elektřiny (variable electricity rate) or variabilní kvalita výrobku (variable product quality). In genetics and biology, variabilita (variability) and variabilní znaky describe differences among individuals, such as genetic diversity or variable phenotypic traits.

Overall, variabilní functions as a technical descriptor across disciplines to signal non-fixed, condition-dependent characteristics, while variabilita remains the core noun for the concept of variability.
