Match the type of variable in List I with its basic feature in List II and choose the correct answer from the options given below:
List I
- Independent variable
- Dependent variable
- Intervening variable
List II
- Predictor variable
- Tells the relationship between two variables
- Outcome variable
AI-b, II-c, III-a
BI-a, II-c, III-b ✓ Correct
CI-c, II-a, III-b
DI-a, II-b, III-c
Correct answer: (B) I-a, II-c, III-b — The correct match is I-a, II-c, III-b.
Explanation
★The correct match is I-a, II-c, III-b.
★The independent variable is the cause that the teacher or researcher manipulates, so it acts as the predictor variable.
★The dependent variable is what changes in response, such as student performance, so it is the outcome variable.
★The intervening variable comes between the two and helps explain the relationship between them.
★In teaching research the teacher's action is treated as independent while the student's result is dependent.
★The intervening variable thus links cause and effect by telling how the independent variable acts on the dependent one.
