What is approximate curve?

Approximation (interpolation) is a generating principle, which enables to model connected curve segments from the discrete ordered sets of points in the extended Euclidean space.

How do you find the best fit curve?

A line of best fit can be roughly determined using an eyeball method by drawing a straight line on a scatter plot so that the number of points above the line and below the line is about equal (and the line passes through as many points as possible).

What are the methods used in curve fitting?

Three methods are available for this purpose; the method of moments, the method of least squares and the method of maximum likelihood.
