Quizplus · Accepted Answer

A spurious relationship means that there is an apparent correlation between X and Y, but this relationship disappears once the effect of Z is controlled. Option A correctly identifies this characteristic of a spurious relationship. Options B and C describe the relationships where the dependent variable either increases or decreases exponentially with the independent variable, but they do not necessarily indicate a spurious relationship. Option D is incorrect as option C is not a correct choice.
