The mean deviation from the mean of the discrete data \(2,3,5,7,11,13,17,19,22\) is
- A 8
- B 7.5
- C 5.5
- D 6
Answer & Solution
Correct Answer
(D) 6
Step-by-step Solution
Detailed explanation
\(\bar{x} = \frac{2+3+5+7+11+13+17+19+22}{9} = \frac{99}{9} = 11\) \(\text{MD} = \frac{|2-11|+|3-11|+|5-11|+|7-11|+|11-11|+|13-11|+|17-11|+|19-11|+|22-11|}{9}\) \(\text{MD} = \frac{9+8+6+4+0+2+6+8+11}{9}\) \(\text{MD} = \frac{54}{9} = 6\)
