H3 When to Use Residual Plots?

At its core, a residual represents the difference between an observed value and a predicted value. In other words, it's the amount of variation between what we expect to happen and what actually occurs. Residuals can be positive or negative, and their magnitude and direction provide valuable insights into the underlying relationships between variables.
