Answer:
4
Step-by-step explanation:
Finding the mean :
- 105 + 106 + 120 + 111 + 109 + 104 + 110 + 115 / 8
- 880/8
- 110
Absolute Mean Deviation of each term :
- |110 - 105| = 5
- |110 - 106| = 4
- |120 - 110| = 10
- |111 - 110| = 1
- |110 - 109| = 1
- |110 - 104| = 6
- |110 - 110| = 0
- |115 - 110| = 5
M.A.D. = 5 + 4 + 10 + 1 + 1 + 6 + 0 + 5 / 8
