Correct answer: C. Statement I is true but Statement II is falseकथन I सत्य है, लेकिन कथन II असत्य है
Explanation
In a panel design the same respondents are measured repeatedly, so the data are dependent and need special analysis (e.g. repeated-measures methods) – Statement I is true. Because the same people must be followed over time, some drop out (panel attrition or 'mortality'), which is a well-known weakness – Statement II is false. Answer: Statement I is true but Statement II is false.पैनल अभिकल्प में उन्हीं उत्तरदाताओं का बार-बार मापन होता है, अतः आँकड़े परस्पर निर्भर होते हैं और विशेष विश्लेषण (जैसे पुनरावृत्त मापन विधियाँ) की आवश्यकता होती है – कथन I सत्य है। उन्हीं लोगों का लंबे समय तक अनुसरण करने पर कुछ लोग छूट जाते हैं (पैनल क्षरण या 'मृत्यता'), जो इसकी प्रसिद्ध कमी है – कथन II असत्य है। उत्तर: कथन I सत्य है, लेकिन कथन II असत्य है।More Research Aptitude questions
