Answer:
Mean absolute deviation of the heights is 3.
Explanation:
Given the heights: 75, 78, 77, 79, 83, 85
Average value, X = 
= 79.5
Mean absolute deviation = 
(/
- X/ + /
- X/ + /
- X/ + /
- X/ + /
- X/ + /
- X/)
Mean absolute deviation = 
(/75 - 79.5/ + /78 - 79.5/ + /77 - 79.5/ + /79 - 79.5/ + /83 - 79.5/ + /85 - 79.5/)
= (4.5 + 1.5 + 2.5 + 0.5 + 3.5 + 5.5)
= (18)
= 3
The mean absolute deviation of the heights is 3.
