The mean deviation about the median of the following distributions is
- A 7.5
- B 8.4
- C 9.2
- D 9.6
Answer & Solution
Correct Answer
(A) 7.5
Step-by-step Solution
Detailed explanation
\(\because\) Here, \(n=7\) (odd) \(\therefore\) Median \(=\left(\frac{n+1}{2}\right)\) observation \( =4 \text { observation }=24 \) Mean deviations \( =\frac{\Sigma f i\left(x_1-\text { Median }\right)}{\Sigma f i}=\frac{510}{68}=7.5 \)
