Interpolation is a way to estimate values between two points of a data set. Most of the real-world data are available as discrete points. Interpolation comes handy if you want to estimate the data between two points. The most simple interpolation is a linear interpolation, where variation of data between two data points is assumed linear. Let us consider the following example. We have of density of water at different… Read More »Automated interpolation formula for Excel: Define excel interpolate function & use it forever
