## parameterAn independent variable; one of the inputs for a function. Parametric equations are equations in which the variables
of interest in are given in terms of another variable. For example, f(x)
= ax^{2} + b is the general equation of a set
of points corresponding to a parabola,
expressed in terms of the parameters a and b. Substitutions
of specific values of these defines a particular set. In statistics, the
parameters of a distribution are those elements of it which can be used
to loosely define it. They may be location parameters, such as the mean,
median, and mode, or parameters of dispersion, such as the standard
deviation. ## Related category• FUNCTIONS | |||||
