Interpolation error

Interpolation error refers to the difference between the actual value of a point and the value estimated by an interpolation method. When we estimate a value between known data points, the interpolation uses a mathematical formula to predict this unknown point. However, because the formula is an approximation, it may not perfectly match the true value, resulting in an error. This error can vary depending on how many data points are used, how they are spaced, and the nature of the data itself. Understanding interpolation error helps assess the reliability of the estimated values.
