-If a residual plot shows an almost straight line then a linear model is appropriate.

Question

Quizplus · Accepted Answer

If a residual plot (which plots the residuals on the y-axis versus the predicted values on the x-axis) shows an almost straight line, it indicates that the residuals are randomly distributed around zero without any apparent pattern. This randomness suggests that the linear model has captured the relationship between the variables well, making a linear model appropriate for the data.
