Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: So that rules are not changed to suit the resultताकि परिणाम के अनुसार नियम न बदले जाएँ
A pre-decided measurement method reduces selective interpretation and bias. In exams remember the value of an operational definition.पूर्व निर्धारित मापन विधि चयनात्मक व्याख्या और पक्षपात घटाती है। परीक्षा में संचालनात्मक परिभाषा का महत्व याद रखें।
