Consider the followoing distribution
The sum of the mean deviation from the mean and the mean deviation from median of this distribution is
- A 6
- B \(\frac{16}{9}\)
- C 54
- D \(\frac{32}{9}\)
Answer & Solution
Correct Answer
(D) \(\frac{32}{9}\)
Step-by-step Solution
Detailed explanation
Computation of mean deviation about mean We have, \( \bar{x}=\frac{\Sigma f_i X_i}{\Sigma f_i}=\frac{54}{9}=6 \Rightarrow M D=\frac{\Sigma f_i\left|x_i-\bar{x}\right|}{\Sigma f_i}=\frac{16}{9} \) Computation of mean deviation about median We have, \(\quad N=9\)…
