![]() ![]() We need the value of y corresponding to x, which makes point B(x,y). The mathematical equation for this case is as follows: Mathematical Equation for Linear Interpolation Suppose, we name this point B we’ll also call the two points that we need for interpolating, A(7,14) and C(9,19). We will introduce four ways to determine this value. ![]() We need to know the y value corresponding to x=18.1. For example, suppose we have a dataset of x and y values. Linear interpolation is the crossing of a straight line between two data points. When our data is not linear, linear interpolation does not give an accurate estimation. In this case, linear interpolation is useful to predict an unknown value. The data we are working with is sometimes linear, or approximately linear. In other words, interpolation is estimating an unknown value between two known values. To estimate this unknown value, we should interpolate. ![]() Suppose we have a function with discrete points, and we need a value between two specific values of the function. Nonlinear Interpolation Using Trendline.Mathematical Equation for Linear Interpolation.In this blog, we are going to learn about interpolation and how it’s done in Excel. Interpolation is a useful mathematical and statistical method used to estimate an unknown value of a function between two known values. ![]()
