Which statement correctly describes Matthew’s data?

A. The median number of pets the students have is less than the median number of siblings the students have.

B. There is less variability in the number of pets the students have than in the number of siblings the students have.

C. The range in the number of siblings the students have is less than the range in the number of pets the students have.

D. The mean absolute deviation of the number of siblings the students have is less than the mean absolute deviation of the number of pets the students have.

Answer:

B. There is less variability in the number of pets the students have than in the number of siblings the students have.

Step-by-step explanation:

From the data:

Pets data:

3,3,4,4,4,4,5,5,5,5

Using calculator:

Median value = 4

Mean absolute deviation = 0.64

Range = 5 - 3 = 2

Siblings data:

Median value = 2

Mean absolute deviation = 1.52

Range = 5 - 0 = 5

Median value of pets > median value of siblings data

Range of siblings data > range of pets data

Mean absolute deviation of siblings data >Ean absolute deviation of pets data

Variability of pets data is lesser than that of siblings data ; as shown by the mean absolute deviation value
