The mean deviation from the mean for the data \(6,7,10\), \(12,13,4,12,16\) is
- A \(3: 25\)
- B \(3.52\)
- C \(3.33\)
- D \(2.35\)
Answer & Solution
Correct Answer
(A) \(3: 25\)
Step-by-step Solution
Detailed explanation
Mean \(=\frac{6+7+10+12+13+4+12+16}{8}=10\) Mean deviation \[ \begin{aligned} & |6-10|+|7-10|+|10-10|+|12-10|+|13-10| \\ = & \frac{+|4-10|+|12-10|+|16-10|}{8} \\ = & \frac{4+3+0+2+3+6+2+6}{8}=\frac{26}{8}=3.25 \end{aligned} \]
