What does parametric mean?
Parametric describes something that is expressed or governed by one or more parameters, which are variables used to specify particular conditions or characteristics. The idea is especially important in mathematics, where parametric equations describe relationships by expressing one coordinate in terms of another and a parameter. It is also common in statistics, engineering, architecture, and computer graphics: a parametric model allows designers to adjust variables and see how those changes affect the result. The word is thus associated with flexibility, systematic variation, and the ability to represent many cases through a common structure. In general use, it is more technical than a simple synonym for adjustable and should generally be reserved for contexts involving mathematical, scientific, statistical, or design systems. Its opposite, nonparametric, is especially established in statistics.
Relating to, or determined by, one or more parameters; expressed in terms of variables that specify particular conditions.
"The team compared several parametric designs before choosing the most efficient one."
Common in mathematics, statistics, engineering, computer graphics, and design. In statistics, it contrasts with nonparametric.
A parameter or variable used in a mathematical, technical, or design system, especially as part of a collection of adjustable values.
"The designer adjusted the key parametrics of the model before running the simulation."
The noun form is relatively uncommon and is mainly used in technical contexts; the plural parametrics is used when referring to several such values or settings.
The plural is relatively uncommon and is used mainly in technical contexts.
"The engineers changed the parametrics to improve the model's performance."
Parametric thinking turns changing conditions into variables, allowing a single model to describe many possibilities.

Where does parametric come from?
Parametric comes from the Greek prefix para-, meaning “beside” or “alongside,” and the stem metric, associated with measuring. It developed through the mathematical term parameter, from Greek parametron, a term associated with measuring alongside a reference. English acquired the related adjective in the 19th century, when it was used chiefly in mathematical and scientific writing.

How parametric is actually used
The term is most common in mathematics, statistics, engineering, computer graphics, and design. In statistics, a parametric method assumes a specified distribution or form; the contrast is with a nonparametric method. It is usually more technical than a general synonym for customizable.
