  # Perameter vs. Parameter: What's the Difference? Edited by Huma Saeed || By Sawaira Riaz || Updated on November 1, 2023
Perameter is an incorrect spelling, while Parameter is the correct spelling that refers to a defining or limiting factor. ## Which is correct: Perameter or Parameter

How to spell Parameter? ### Perameter is Incorrect ## Key Differences

Think of "para-" like parachute, both start with the correct "para-" prefix.
"Meter" refers to measurement, but "Parameter" is more about defining factors.
Recall mathematical terms: perimeter (boundary) vs. parameter (variable). Different meanings, different spellings.
Remember it by the phrase: "Set the parameters, not the perameters."
Visualize a meter measuring the "peri" or boundary, and a defined rule or limit as "parameter."

## Perameter and Parameter Definitions

#### Perameter

Perameter is an incorrect spelling of Parameter.

#### Parameter

In mathematics, a quantity that influences the output but remains constant.
In the equation y = ax + b, a is a parameter.

#### Parameter

A numerical or other measurable factor that serves as a defining characteristic.
The device can operate within certain parameters.

#### Parameter

In computing, a value passed to a function.
The function requires three parameters.

#### Parameter

A guideline or characteristic for a task.
The project's parameters were clearly defined.

#### Parameter

A constant in an equation that varies in other equations of the same general form, especially such a constant in the equation of a curve or surface that can be varied to represent a family of curves or surfaces.

#### Parameter

One of a set of independent variables that express the coordinates of a point.

#### Parameter

One of a set of measurable factors, such as temperature and pressure, that define a system and determine its behavior and are varied in an experiment.

#### Parameter

Usage Problem A factor that restricts what is possible or what results
"all the parameters of shelter—where people will live, what mode of housing they will choose, and how they will pay for it" (New York).

#### Parameter

A factor that determines a range of variations; a boundary
An experimental school that keeps expanding the parameters of its curriculum.

#### Parameter

(Statistics) A quantity, such as a mean, that is calculated from data and describes a population.

#### Parameter

Usage Problem A distinguishing characteristic or feature.

#### Parameter

A value kept constant during an experiment, equation, calculation, or similar, but varied over other versions of the experiment, equation, calculation, etc.

#### Parameter

(sciences) A variable that describes some system (material, object, event, etc.) or some aspect thereof.

#### Parameter

(statistics) Any measured quantity of a statistical population that summarises or describes an aspect of the population.

#### Parameter

(machine learning) A variable of a model that is trained by a machine learning algorithm.

#### Parameter

(programming) An input variable of a function definition, that gets an actual value (argument) at execution time.

#### Parameter

An actual value given to such a formal parameter.

#### Parameter

A characteristic or feature that distinguishes something from others.

#### Parameter

(geometry) 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 parameter of the principal axis of a conic section is called the latus rectum.

#### Parameter

(crystallography) The ratio of the three crystallographic axes which determines the position of any plane.

#### Parameter

(crystallography) The fundamental axial ratio for a given species.

#### Parameter

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.

#### Parameter

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.

#### Parameter

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.

#### Parameter

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

#### Parameter

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.

#### Parameter

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.

#### Parameter

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

#### Parameter

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

#### Parameter

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

#### Parameter

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

#### Parameter

A boundary or limit.
We need to work within the parameters of the budget.
