Correct Answer: Option D
Explanation:
\(\bar{x}\) = \(\frac{30}{5}\) = 6
\(\sum |x - \bar{x}|\)
= 10
Mean deviation = \(\frac{10}{5}\)
= 2
| x | x - \(\bar{x}\) | (x - \(\bar{x}\)) |
| 58296 | -12-430 | 12430 |
\(\bar{x}\) = \(\frac{30}{5}\) = 6
\(\sum |x - \bar{x}|\)
= 10
Mean deviation = \(\frac{10}{5}\)
= 2
