Given below are two statements:
Statement (I): If there are few extreme scores in the distribution, mode will be the most appropriate measure of central tendency.
Statement (II): Mean deviation is the most sophisticated measure of dispersion of distribution.
In the light of the above statements, choose the correct answer from the options given below:नीचे दो कथन दिए गए हैं:
कथन (I): यदि किसी वितरण में कुछ आत्यंतिक प्राप्तांक हैं, तो बहुलक केंद्रीय प्रवृत्ति का सर्वाधिक उपयुक्त माप होगा।
कथन (II): माध्य विचलन वितरण के प्रकीर्णन का सर्वाधिक समुन्नत माप है।
उपर्युक्त कथनों के आलोक में, नीचे दिए गए विकल्पों में से सही उत्तर चुनिए:

Show answer & explanation
Correct answer: B. Both Statement (I) and Statement (II) are falseकथन (I) और कथन (II) दोनों असत्य हैं
Explanation
When a distribution contains extreme scores, the median — not the mode — is the most appropriate measure of central tendency, because the median is unaffected by extreme values; so Statement (I) is false. The most sophisticated (mathematically refined and most widely used) measure of dispersion is the standard deviation, not mean deviation; so Statement (II) is also false. Hence both statements are false.जब किसी वितरण में आत्यंतिक प्राप्तांक होते हैं, तब केंद्रीय प्रवृत्ति का सर्वाधिक उपयुक्त माप माध्यिका होती है, बहुलक नहीं, क्योंकि माध्यिका आत्यंतिक मानों से प्रभावित नहीं होती; अतः कथन (I) असत्य है। प्रकीर्णन का सर्वाधिक समुन्नत माप मानक विचलन है, माध्य विचलन नहीं; अतः कथन (II) भी असत्य है। इसलिए दोनों कथन असत्य हैं।More Research Aptitude questions
