A student slightly changes the procedure after every trial but averages all results together. What is the problem?एक प्रयोग में छात्र हर परीक्षण के बाद प्रक्रिया थोड़ा बदलता है लेकिन सभी परिणाम एक साथ औसत करता है। इसमें क्या समस्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: The trials were not conducted under identical conditionsपरीक्षण समान परिस्थितियों में नहीं हुए
Results from different procedures are not directly comparable. In exams keep the method constant during repetitions.अलग प्रक्रियाओं से प्राप्त परिणाम सीधे तुलनीय नहीं होते। परीक्षा में दोहराव के दौरान विधि समान रखें।
