Below are two residual plots A residual plot is a graph of t

Below are two residual plots. A residual plot is a graph of the difference between the theoretical and experimental dependent values. Which of the two residual plots shows a better regression and why? A. The residuals make a pattern. B. The residuals are randomly positive and negative. A. The regression function is a quadratic because the residuals create a parabola. B. Because there is a 3:2 ratio of positive residuals to negative residuals.

Solution

A) is better over B. as A makes a schematic pttern and the B has random data also B ha no any + point from precision side. so A is better
