Someone help me please

Answer 1

Mean: 8 gerbils

MAD: 4.29 gerbils

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
