Linear interpolation is used to find an unknown value of a function between any two known points. The formula for linear interpolation is y = y 1 + ( x - x 1) ( y 2 - y 1) ( x 2 - x 1) Linear interpolation can also be used to find the median, 1 st quartile and 3 rd quartile. The position of the median is n 2.
