Problems 5 through 7 have two data sets represented. Fill in the blanks to make a comparison statement and explanation.

5.

Data Set A

a box plot 404040424242444444464646484848505050525252545454565656585858606060626262

Data Set B

a box plot 404040424242444444464646484848505050525252545454565656585858606060626262646464666666686868707070727272747474767676787878808080

Data set B has a greater than data set A, which means that more of the values in Data Set B are .

Data Set A

a histogram skewed to the left 222444666888101010222444666888000

Data Set B

a histogram skewed to the right 222444666888101010222444666888000

Data Set A is , while Data Set B is , which means that .

Data Set B

a box plot 333444555666777888999

Data Set A has a greater than Data Set B, which means that its values are .

Use these box plots to answer problems 9 through 11.

Box plot X

a box plot 333444555666777888999

Box plot Y

a box plot 222444666888101010121212141414

9.

Find the median, range, and interquartile range for box plot X.

10.

Find the median, range, and interquartile range for box plot Y.

Range:

Interquartile range:

11.

If the box plots X and Y represent the results of two different classes on the same assessment, which class did better?

The two box plots below show the low temperatures for two cities in the United States. City D is the box plot on top, and City E is the box plot on the bottom. Use these box plots for problems 12 through 15.

12.

Which city would be considered the coldest, City D or City E? Why?

13.

Do these cities ever experience the same temperature? How do you know?

14.

Comparing the two sets of data, can you provide information about their shape, center, and spread?

15.

What advantage, if any, could a histogram of temperature data have over a box plot?
