This page provides all possible meanings and translations of the word Parameter

Princeton's WordNet

  1. parameter, parametric quantity(noun)

    a constant in the equation of a curve that can be varied to yield a family of similar curves

  2. parameter(noun)

    any factor that defines a system and determines (or limits) its performance

  3. argument, parameter(noun)

    (computer science) a reference or value that is passed to a function, procedure, subroutine, command, or program

  4. parameter(noun)

    a quantity (such as the mean or variance) that characterizes a statistical population and that can be estimated by calculations from sample data


  1. Parameter(n.)

    A constant number which is part of a theory, function, or calculation, whose value is not determined by the form of the theory or equation itself, and may in some cases be arbitrary assigned.

  2. Parameter(n.)

    (Science) Any constant number which is required to calculate values of observed phenomena according to a theory, but the value of which must be determined by experiment, and cannot be calculated from the fundamental assumptions of the theory. In general, a theory which has a large number of parameters, though it may accurately predict experimental results, is considered as having less explanatory power and as being less esthetically pleasing than a theory with fewer parameters.

  3. Parameter(n.)

    The limits, guidelines, or assumptions from within which an activity is carried out; as, new arrivals need to learn the parameters of the research in our department.

  4. Parameter(n.)

    (Computers) A variable used in a calculation within a computer program which must be assigned a value before the calculation can be performed; as, let's plug in the parameters and see what the result is.

  5. Parameter(n.)

    A characteristic or element, especially one used as a criterion for evaluation or judgment; as, a useful parameter for determining efficiency.

  6. Origin: [Pref. para- + -meter: cf. F. paramtre.]


  1. parameter(Noun)

    A variable kept constant during an experiment, calculation or similar.

  2. parameter(Noun)

    A name in a function or subroutine definition that is replaced by, or bound to, the corresponding actual argument when the function or subroutine is called: a formal parameter.

    Roughly, a tuple of arguments could be thought of as a vector, whereas a tuple of parameters could be thought of as a covector (i.e., linear functional). When a function is called, a parameter tuple becomes "bound" to an argument tuple, allowing the function instance itself to be computed to yield a return value. This would be roughly analogous to applying a covector to a vector (by taking their dot product (or, rather, matrix-product of row vector and column vector)) to obtain a scalar.

  3. parameter(Noun)

    The value which is passed into the function to instantiate such a name; the argument or actual parameter.

  4. parameter(Noun)

    A characteristic or feature that distinguishes something from others

  5. Origin: From paramètre, from parametrum, from παρά + μέτρον.

Webster Dictionary

  1. Parameter(noun)

    a term applied to some characteristic magnitude whose value, invariable as long as one and the same function, curve, surface, etc., is considered, serves to distinguish that function, curve, surface, etc., from others of the same kind or family

  2. Parameter(noun)

    specifically (Conic Sections), in the ellipse and hyperbola, a third proportional to any diameter and its conjugate, or in the parabola, to any abscissa and the corresponding ordinate

  3. Parameter(noun)

    the ratio of the three crystallographic axes which determines the position of any plane; also, the fundamental axial ratio for a given species

  4. Origin: [Pref. para- + -meter: cf. F. paramtre.]


  1. Parameter

    Parameter can be interpreted in mathematics, logic, linguistics, environmental science and other disciplines. In its common meaning, the term is used to identify a characteristic, a feature, a measurable factor that can help in defining a particular system. A parameter is an important element to take into consideration for the evaluation or for the comprehension of an event, a project or any situation.
