Quizplus · Accepted Answer

Variables can refer to either a concept that can be measured (such as height or weight) or an idea that can be manipulated (such as intelligence or happiness). Therefore, some variables can be either manipulated or measured. Option A is incorrect because variables and constants are not the same. Option B is incorrect because not all variables can be manipulated, as some may only be measured. Option D is incorrect because variables need both conceptual and operational definitions.
