LESSON 1
Interpreting Box and Whisker Plots
Use the box plot that shows the ages of U.S. vice presidents when they took office.
1. Describe the distribution of the data. What can you say
about the ages of U.S. vice presidents?
2. What percent of U.S. vice presidents were at least 60
years old when they took office? Explain how you
found your answer.
3. What percent of U.S. vice presidents were between the
ages of 49 and 60 when they took office? Explain how
you found your answer.
4. Can you determine from the box plot whether there are
any U.S. vice presidents who took office at exactly age
55 years of age? Explain.
Use the box plot that shows the number of goals made by members of the field hockey team during the season.
5. Describe the distribution of the data. What can you say
about the number of goals made by the members of the
field hockey team?
6. What percent of team members scored between 1 and
3 goals this season? Explain.

Transformations on a Map
Directions: Use the map of the United States and the coordinate plane that it is drawn on to do the
following transformations. Read each scenario carefully and pay attention to details.
