Question

which residual plot shows that the model is a good fit for the data?

Explanation:

A good - fit model in a residual plot has residuals that are randomly scattered around the horizontal axis (residual = 0). There is no pattern (such as a curve, increasing or decreasing trend) in the residuals.

• In the first plot, there is a clear decreasing trend in the residuals.
• In the second plot, there is a non - random pattern (a sort of "wave" or non - linear pattern) in the residuals.
• In the third plot, the residuals are randomly scattered around the horizontal axis.

Answer:

The third residual plot.
