AA categorical variable
BA dependent variable
CAn independent variable ✓ Correct
DAn intervening variable
Correct answer: (C) An independent variable — A variable presumed to cause a change in another is the independent variable, so that is the answer.
Explanation
★A variable presumed to cause a change in another is the independent variable, so that is the answer.
★The independent variable is treated as the cause in the study.
★So it is the one presumed to bring about the change in another variable.
★A categorical variable is just a variable measured in categories, not necessarily a cause.
★The dependent variable is the effect that changes, not the presumed cause.
★An intervening variable comes between cause and effect, so the presumed cause is the independent variable.
