Answer:
Mean: 8 gerbils
MAD: 4.29 gerbils
Step-by-step explanation:
✔️Mean = sum of all numbers ÷ 7
Mean = (0 + 3 + 6 + 9 + 11 + 13 + 14) ÷ 7 = 56/7 = 8.
✔️MAD:
Find sum of |data value - mean| divided by number of values (7)
|0 - 8| = 8
|3 - 8| = 5
|6 - 8| = 2
|9 - 8| = 1
|11 - 8| = 3
|13 - 8| = 5
|14 - 8| = 6
MAD = (8 + 5 + 2 + 1 + 3 + 5 + 6) ÷ 7 = 30/7 ≈ 4.29
