The mean deviation from the arithmetic mean of the discrete data \(2,7,5,6,4,3,11,17,8\) is
- A \(\frac{17}{2}\)
- B \(\frac{10}{3}\)
- C \(\frac{37}{2}\)
- D \(9\)
Answer & Solution
Correct Answer
(B) \(\frac{10}{3}\)
Step-by-step Solution
Detailed explanation
Given observations are \(2,7,5,6,4,3,11,17,8\). \(\therefore \quad \bar{x}=\frac{2+7+5+6+4+3+11+17+8}{9}=\frac{63}{9}=7\) Now, \(M D=\frac{\Sigma d_i}{N}=\frac{30}{9}=\frac{10}{3}\)
