The residual plot attached to the question is a good residual plot
How to determine if the residual plot attached is good or bad
From the question, we have the following parameters that can be used in our computation:
The residual plot
By definition:
A good residual plot should appear random and not follow any specific pattern.
This means that a good residual plot shows no clear trend
From the figure, we can see that the dots on the plot are scattered
Hence, the residual plot attached is good
