Consider the plot created from the residuals of a line of best fit for a set of data.

A graph shows both axes unnumbered. Points show a steady trend.
Does the residual plot show that the line of best fit is appropriate for the data?

Yes, the points have no pattern.
No, the points are evenly distributed about the x-axis.
No, the points are in a linear pattern.
Yes, the points are in a curved pattern.

No, the points are in a linear pattern.

Explanation: residuals should be randomly scattered around zero if a linear model is appropriate. A steady/trending pattern (here a linear trend) shows systematic error, so the straight-line fit is not appropriate.
