Calculate the mean deviation of 5, 8, 2, 9 and 6
...Calculate the mean deviation of 5, 8, 2, 9 and 6
5
4
3
2
Correct answer is D
| x | x - \(\bar{x}\) | (x - \(\bar{x}\)) |
|
5 8 2 9 6 |
-1 2 -4 3 0 |
1 2 4 3 0 |
\(\bar{x}\) = \(\frac{30}{5}\) = 6
\(\sum |x - \bar{x}|\)
= 10
Mean deviation = \(\frac{10}{5}\)
= 2
