parameter, parametric quantity(noun)
a constant in the equation of a curve that can be varied to yield a family of similar curves
any factor that defines a system and determines (or limits) its performance
(computer science) a reference or value that is passed to a function, procedure, subroutine, command, or program
a quantity (such as the mean or variance) that characterizes a statistical population and that can be estimated by calculations from sample data
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.
(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.
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.
(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.
A characteristic or element, especially one used as a criterion for evaluation or judgment; as, a useful parameter for determining efficiency.
Origin: [Pref. para- + -meter: cf. F. paramtre.]
A variable kept constant during an experiment, calculation or similar.
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.
The value which is passed into the function to instantiate such a name; the argument or actual parameter.
A characteristic or feature that distinguishes something from others
Origin: From paramètre, from parametrum, from παρά + μέτρον.
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
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
the ratio of the three crystallographic axes which determines the position of any plane; also, the fundamental axial ratio for a given species
Origin: [Pref. para- + -meter: cf. F. paramtre.]
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.
Chambers 20th Century Dictionary
par-am′ē-tėr, n. (geom.) the constant quantity which enters into the equation of a curve: in conic sections, a third proportional to any diameter and its conjugate diameter. [Gr. para, beside, metron, measure.]

Sample Sentences & Example Usage
You can't have people policing every parameter of a prison at all times, there's usually one person out there and they aren't looking for a football.
I always strive to be objective and well-balanced spectator of the situation, instead of enforcing my personal viewpoints on my readers. I believe that such an elegant approach does the best justice to subject matter. Objectivity is always the key and most important parameter in all processes of Life!
My writing may not fully represent either my thought process or my personal sentiments at the time of writing those thoughts - because I always strive to be objective and well-balanced spectator of the situation, instead of enforcing my personal standpoints to my readers. I believe that such approach does the best justice to subject matter. Objectivity is always the key and important parameter in all processes of Life!
