Quizplus · Accepted Answer

The independent variable is the variable that is being manipulated by the researcher, while the dependent variable is the variable being measured for its effects. Therefore, option B (independent variable; dependent variable) is the correct answer. Option A (dependent variable; independent variable) is incorrect because it contradicts the correct relationship between the two variables. Option C (operational variable; dependent variable) is incorrect because the operational variable is a specific way of measuring or defining a variable, not the variable itself. Option D (independent variable; operational variable) is incorrect because it confuses the manipulation of the variable with the way it is measured.
