The mean deviation from the median for the following data is
- A \(0.75\)
- B \(7.5\)
- C \(0.65\)
- D \(0.40\)
Answer & Solution
Correct Answer
(A) \(0.75\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & N=48 \\ & \frac{N}{2}=24\end{aligned}\) \(\therefore\) Median \(=24\) th observation \(=12\) \(\begin{aligned} N & =48 \\ \mathrm{MD} & =\frac{\Sigma f_i\left|x_i-M\right|}{N}=\frac{36}{48}=0.75\end{aligned}\)
