58, 65, 42, 66, 49, 59, 44, 45, 62, 60
निम्नलिखित आंकड़ा-समुच्चय के माध्य (Mean) से माध्य विचलन (Deviation) ज्ञात कीजिए।
58, 65, 42, 66, 49, 59, 44, 45, 62, 60
58, 65, 42, 66, 49, 59, 44, 45, 62, 60
Answer और ExplanationAnswer and explanation
Answer: (B) 8
माध्य = 55010 = 55
विचलन |x − 55|: 3, 10, 13, 11, 6, 4, 11, 10, 7, 5, कुल 80
माध्य विचलन (Mean deviation) = 8010 = 8
✓
माध्य विचलन 8 है।
Mean = 55010 = 55
Deviations |x − 55|: 3, 10, 13, 11, 6, 4, 11, 10, 7, 5, total 80
Mean deviation = 8010 = 8
✓
The mean deviation is 8.
