Quizplus · Accepted Answer

When two variables covary, it means that they tend to vary together. This implies that a change in one variable is accompanied by a consistent change in the other variable. Therefore, option C is the correct answer. Option A is incorrect because covariation implies a consistent change. Option B is incorrect because the relationship between the two variables could be positive, negative, or non-existent. Option D is incorrect because covariation does not necessarily imply that the two variables have the same mean.
