+**Interpolation** is the process of estimating unknown values that lie between a set of known [Data Points](/wiki/data-points). It seeks to construct new data points within the range of a discrete set of known data, effectively "filling in the gaps." This technique is widely used in [Numerical Analysis](/wiki/numerical-analysis) and various scientific computations to approximate continuous functions.
