Residual Plot: Scatterplot of the Residuals vs. Explanatory Variable

• Plot the residuals on the y-axis and the explanatory variable on the x-axis.
• If the regression line captures the relationship between the response and the explanatory variable, the residuals should
• Be centered around 0.
• Not display any pattern.

=> If the model is adequate for explaining the relationship the residual plot should look like a cloud of dots scattered evenly around 0.
