Tom and Susan park at different lots. To see which lot is busier, they count the numbers of cars in the lots each day as they arrive.

Their data are shown in the box plots.

the questions to compare the variabilities of the data sets.

1. What is the interquartile range for Tom's data? Explain how you found the interquartile range.

Write your answer in the space below.

1

Tom = 5

Susan = 3

Step-by-step explanation:

FROM THE BOXPLOT :

Tom's IQR :

IQR = Q3 - Q1

Q3 = third quartile (value at the endpoint of the box)

Q1 = 1st quartile (value at the beginning of the box)

IQR = 9 - 4

IQR = 5

SUSAN :

IQR = Q3 - Q1

Q3 = third quartile (value at the endpoint of the box)

Q1 = 1st quartile (value at the beginning of the box)

IQR = 8 - 5

IQR = 3

answer: 5100 just subtract
