Answer 1

Answer:

C. 3.2

Step-by-step explanation:

Heights of dogs: 10, 22, 15, 12, 16

✔️Find the mean of the data set = $\frac{10 + 22 + 15 + 12 + 16}{5} = \frac{75}{5} = 15$

✔️Find |data value - mean|:

|10 - 15| = 5

|22 - 15| = 7

|15 - 15| = 0

|12 - 15| = 3

|16 - 15| = 1

✔️Find the sum of |data value - mean| and divide by 10:

$\frac{5 + 7 + 0 + 3 + 1}{5} = \frac{16}{5} = 3.2$

✅M.A.D = 3.2
