The mean deviation about the median for the following data \(6,3,4,9,2,7\) and 11 is
- A \(1.89\)
- B \(2.57\)
- C \(3.14\)
- D \(6.23\)
Answer & Solution
Correct Answer
(B) \(2.57\)
Step-by-step Solution
Detailed explanation
Given data is 6, 3, 4, 9,2,7 and 11 There are total 7 observation which isodd. So, Median \(=\) \(\left(\frac{\mathrm{x}-1}{2}\right)^{\mathrm{th}}=\left(\frac{\mathrm{x}+1}{2}\right)^{\mathrm{th}}=\frac{8^{\mathrm{th}}}{2}=4^{\text {th }}\) Observation are \(2,3,4,6,7,9,11\)…
