interpolation

Interpolation is a method used to estimate unknown values between known data points. Imagine you have a series of measurements—like the temperature at different times of the day. If you know the temperature at noon and at 2 PM, you can use interpolation to predict the temperature at 1 PM, based on the trend between these two points. This technique is widely used in various fields, such as science, engineering, and statistics, to fill in gaps and make informed predictions based on existing information.
