Question

each graph shows a set of residuals for a different set of data points. which residual plots represent a function that is a relatively good fit to the data? select all that apply.

Explanation:

A good - fit function in a residual plot has residuals randomly scattered around the \(x\) - axis.

• In the first plot, the residuals are not randomly scattered (there is a pattern).
• In the second plot, the residuals are randomly scattered around the \(x\) - axis.
• In the third plot, the residuals are not randomly scattered (there is a pattern).
• In the fourth plot, the residuals are randomly scattered around the \(x\) - axis.

Answer:

The second and fourth residual plots.
