| x | ∴x | x-\(\overline{X}\) | /x-\(\overline{X}\)/ |
| x | 1 | -1 | 1 |
| 2x | 2 | 0 | 0 |
| x+1 | 2 | 0 | 0 |
| 3x | 3 | 1 | 1 |
| ∑/x-\(\overline{X}\)/ = 2 |
Mean(\(\overline{X}\)) = \(\frac{ x + 2x + x + 1 + 3x}{4}\) = 2
2 = \(\frac{7x + 1}{4}\)
8 = 7x + 1
7x = 8 - 1 = 7
x = \(\frac{7}{7}\) = 1
Mean deviation = \(\frac{∑(| x - \overline{X}|)}{n}\)
M.D = \(\frac{2}{4}\) = \(\frac{1}{2}\) = 0.5
There is an explanation video available below.
