Box and Whisker Plot Analysis

A restaurant owner wants to see how far customers travel and what the middle distance is. What kind of graph would best show this information?

• Bar graph

• Line graph

• Box and whisker plot

• Pie chart

The distances customers traveled are: 14, 6, 3, 2, 4, 15, 11, 8, 1, 7, 2, 1, 3, 4, 10, 22, 20. If you put these distances in order from smallest to largest, what would the first three numbers be?

• 1, 2, 3

• 1, 1, 2

• 2, 1, 3

• 1, 2, 4

After ordering the distances from smallest to largest, what is the middle distance traveled by customers? (Ordered data: 1, 1, 2, 2, 3, 3, 4, 4, 6, 7, 8, 10, 11, 14, 15, 20, 22)

• 4

• 6

• 7

• 8

What is the median of the lower half of the data set (1, 1, 2, 2, 3, 3, 4, 4)?

• 2

• 2.5

• 3

• 4

What is the median of the upper half of the data set (7, 8, 10, 11, 14, 15, 20, 22)?

• 10

• 11

• 12.5

• 14

In a box and whisker plot, what does the 'box' part mainly represent?

• The smallest and largest numbers in the data

• The middle half of the data

• Only the median of the data

• The average of all the numbers
