Understanding Linear Interpolation

In various real-world scenarios, we often need more data sets or the need to predict values within a range. Interpolation helps address these gaps by creating a smooth curve that passes through the available data points, enabling us to make accurate predictions within the range.

Several interpolation methods are tailored to different types of data and requirements. Linear interpolation, for instance, connects two adjacent data points with a straight line, while polynomial interpolation employs higher-degree polynomial equations to fit more complex data patterns. Other methods include spline interpolation, which utilizes piecewise-defined functions to ensure continuity and smoothness, and inverse distance weighting for spatial data.

The formula for Calculating Interpolation

Indeed, here’s a general formula for linear interpolation, one of the simplest interpolation methods:

Let’s say you have two data points: `(x1, y1)` and `(x2, y2)`, where `x1` and `x2` are the known independent variable values, and `y1` and `y2` are the corresponding dependent variable values. You want to estimate the value `y` at a point `x` between `x1` and `x2`.

The formula for linear interpolation is:

y = y1 + (x – x1) * ((y2 – y1) / (x2 – x1))

In this formula:
– `x` is the point you want to estimate the value.
– `x1` and `x2` are the known data points.
– `y1` and `y2` are the corresponding values of the dependent variable.

This formula calculates the value `y` by determining the proportional change between `x1` and `x2` and applying the same change to the corresponding `y` values. The `(y2 – y1) / (x2 – x1)` term represents the slope of the line connecting the two data points, and `(x – x1)` represents the difference between the desired point `x` and the starting point `x1`. Adding these components together gives you the estimated value `y`.

It’s important to note that this formula assumes a linear relationship between the data points. Higher-degree polynomial interpolation or other methods might be more appropriate for more complex data patterns.
