The absolute value of a number represents its distance from zero on the number line, regardless of direction. For -7, the absolute value is simply 7, illustrating that distance is always a positive quantity. Understanding this concept is fundamental in mathematics.

By examining these residuals, you can assess model accuracy and identify patterns that might indicate violations of regression assumptions, such as non-linearity or heteroscedasticity.
