Question

The question, “How did the Indian people rate the performance of Finance Minister immediately after the demonetization?” would be addressed using a _______. However, a _______ would be used to address the question, “How did the Indian people change their view of Finance Minister’s performance over the past three years?”

• A. longitudinal design; multiple cross-sectional
• B. cross-sectional design; longitudinal design
• C. longitudinal; cross-sectional design
• D. none of these

Hint:

Think: “Snapshot” = cross-sectional; “Movie over time” = longitudinal.

Answer 1

The Correct Option is B

Step 1: Understanding designs.
- Cross-sectional design: Snapshot at a single point in time — useful for “immediately after” type questions.
- Longitudinal design: Tracks the same group over a long period — suitable for “over the past three years” type questions.
Step 2: Mapping to the question.
- First part (after demonetization) → cross-sectional.
- Second part (past three years) → longitudinal.
Step 3: Elimination.
- (a) Wrong: Order reversed.
- (c) Wrong: Order reversed.
- (d) Wrong: Correct match exists in (b). \[ \boxed{(b)} \]
