We are investigating the relationship among three variables.We have graphed two of them.Suppose that the variable that is not measured on the x-axis or the y-axis changes.Then,there is
A) a movement along the plotted curve.
B) a shift in the plotted curve.
C) no impact on the plotted curve because the variable is not measured on either of the axes.
D) an omitted variable.
E) a violation of the absence of trend assumption.

A change in the variable that is not plotted on the x-axis or y-axis would result in a shift in the plotted curve. This is because the relationship among the three variables would be altered, causing the plotted curve to move to a new position.
