एक प्रयोग में औसत परिणाम समान है लेकिन एक समूह के माप बहुत फैले हुए हैं। इससे क्या संकेत मिलता है?
Two groups have the same mean result but one group has widely spread measurements. What does this indicate?
Explanation opens after your attempt
B. उस समूह की विश्वसनीयता कम हैThat group is less reliable
Concept
Greater spread shows poorer consistency and lower reliability. In exams examine variation as well as the mean.
Why this answer is correct
The correct answer is B. उस समूह की विश्वसनीयता कम है / That group is less reliable. Greater spread shows poorer consistency and lower reliability. In exams examine variation as well as the mean.
Exam Tip
अधिक फैलाव मापों की कम संगति और कम विश्वसनीयता दिखाता है। परीक्षा में केवल औसत नहीं बल्कि फैलाव भी देखें।
