A. दिया गया पानी वास्तविक उपलब्ध जल को सही रूप से न दर्शाए/The water added may not accurately represent the water actually available
Step 1
Concept
Evaporation and drainage can make soil moisture differ even with equal added water. Choose the measure closest to the actual condition.
Step 2
Why this answer is correct
The correct answer is A. दिया गया पानी वास्तविक उपलब्ध जल को सही रूप से न दर्शाए / The water added may not accurately represent the water actually available. Evaporation and drainage can make soil moisture differ even with equal added water. Choose the measure closest to the actual condition.
Step 3
Exam Tip
वाष्पीकरण और जल निकास के कारण समान दी गई मात्रा से अलग मिट्टी नमी हो सकती है। परीक्षा में निकटतम वास्तविक मापन चुनें।
Precisely measuring the wrong variable does not properly test a hypothesis. Distinguish precision from validity.
Step 2
Why this answer is correct
The correct answer is B. मापन वैधता कमजोर / Weak in measurement validity. Precisely measuring the wrong variable does not properly test a hypothesis. Distinguish precision from validity.
Step 3
Exam Tip
गलत चर को परिशुद्धता से मापना भी उचित परिकल्पना परीक्षण नहीं है। परीक्षा में परिशुद्धता और वैधता अलग रखें।
A large sample does not solve the problem of measuring the wrong concept. Check validity along with size.
Step 2
Why this answer is correct
The correct answer is B. कम मापन वैधता / Low measurement validity. A large sample does not solve the problem of measuring the wrong concept. Check validity along with size.
Step 3
Exam Tip
बड़ा नमूना गलत चीज मापने की समस्या दूर नहीं करता। परीक्षा में आकार के साथ वैधता भी जाँचें।
B. मापन की वैधता और पुनरावृत्ति जाँचना कठिन है/Measurement validity and repetition are difficult to assess
Step 1
Concept
Without a clear measurement method the quality of the result is difficult to assess. Understand the importance of operational definitions.
Step 2
Why this answer is correct
The correct answer is B. मापन की वैधता और पुनरावृत्ति जाँचना कठिन है / Measurement validity and repetition are difficult to assess. Without a clear measurement method the quality of the result is difficult to assess. Understand the importance of operational definitions.
Step 3
Exam Tip
स्पष्ट मापन विधि के बिना परिणाम की गुणवत्ता जाँचना कठिन होता है। परीक्षा में परिचालन परिभाषा का महत्व समझें।
