Interpolation
If y is to be estimated for the value of x between two extreme points in a set of values, it is called interpolation.
Interpolation
Consider the profit of a manufacturing company in various years as
given below
The profit for the year 1989 is not available .To estimate the
profit for 1989 we use the technique called interpolation. Let x denote
the year and y denote the profit. The independent variable x is
called the argument and the dependent
variable y is called the entry. If y is to be estimated for the value of x between two extreme
points in a set of values, it is called interpolation.
Methods of interpolation
There are two methods for interpolation. One is Graphical method
and the other one is algebraic method.
