Option b

Explanation:

Box plot method:

Step 1: Find the minimum. Minimum is the smallest data.

Minimum = 5

Step 2: Find the maximum. Maximum is the largest data.

Maximum = 15

Step 3: Arrange the numbers in ascending order.

5, 6, 8, 9, 9, 11, 11, 13, 15

Median = middle term

= 9

Step 4: Find the first quartile. First quartile is the median of the data to the left of the median.

Data left to the median are 5, 6, 8, 9.

Q1 = (6+8) ÷ 2

= 14 ÷ 2

= 7

Step 5: Find the second quartile. Second quartile is the median of the data to the right of the median.

Data left to the median are 11, 11, 13, 15.

Q12 = (11+13) ÷ 2

= 24 ÷ 2

= 12

Answer: Min = 5

Q1 = 7

Median = 9

Q2 = 12

Max = 15
