The butterfly curve can be defined by parametric equations of x and y. In mathematics, a parametric equation expresses several quantities, such as the coordinates of a point, as functions of one or several variables called parameters. [1] In the case of a single parameter, parametric equations are commonly used to express the trajectory of a moving point, in which case, the parameter is often ...

A parametric test is a statistical method that makes specific assumptions about the data it analyzes, most importantly that the data follows a bell-shaped (normal) distribution. Tests like the t-test, ANOVA, and Pearson correlation all fall into this category. They work by using the mathematical properties of that distribution, specifically means and standard deviations, to determine whether ...
Parametric tests are based on assumptions about the distribution of the underlying population from which the sample was taken. The most common parametric assumption is that data are approximately normally distributed. Nonparametric tests do not rely on assumptions about the shape or parameters of the underlying population distribution.
The meaning of PARAMETRIC is of, relating to, or in terms of a parameter.

PARAMETRIC definition: of or relating to a parameter, mathematical or statistical variable. See examples of parametric used in a sentence.
Parametric equation, a type of equation that employs an independent variable called a parameter (often denoted by t) and in which dependent variables are defined as continuous functions of the parameter and are not dependent on another existing variable. More than one parameter can be employed when necessary.
