What can be concluded from the residual plot of a simple linear regression model shown below?

Select one:

a.

The plot indicates that the variance is not constant for this model.

b.

The plot indicates that the linear regression model appears to be appropriate for this set of data.

c.

The plot suggests there is no linear relationship between x and y.

d.

The plot suggests there is no linear relationship between x and y.

Solution

b) is correct

for residual plots, Non-constant variance is suggested by a funnel-like shape when we move from right to left, and nonlinear relationship is suggested by a curved pattern.
