Interpolation is a mathematical method used to estimate values between two known points on a graph or a line. Imagine you have a chart with several points marked on it. Interpolation helps you figure out the value of a point that lies between these marks, even though you haven't measured it directly. It’s like joining the dots to create a smooth line or curve and then finding any value along that line.
This technique is useful in many real-life situations, such as predicting temperatures on a weather graph or finding missing information in a set of data. In the GCSE Maths course, understanding interpolation helps you work with patterns and numbers more accurately.
