World's Best Shoppers!

Materials: calculator, grid paper for making graphs

Work alone or in a group of two or three.

Would you guess that the United States has the most stores of any country in the world? If so, you would be wrong. China is the country with the most stores. The table below shows the ten countries in the world that have the most stores as of 2000. The table also gives the 2000 population of each of the countries listed.

 Country Number of Stores (2000) Population (2000) 1. China 19,306,800 1,261,832,000 2. India 10,537,080 1,014,004,000 3. Brazil 1,595,062 172,860,000 4. Japan 1,240,237 126,550,000 5. Mexico 1,087,995 100,350,000 6. Spain 780,247 39,997,000 7. Vietnam 727,268 78,774,000 8. South Korea 704,032 47,471,000 9. Italy 697,853 57,634,000 10. United States 685,367 275,563,000

Procedure for the Activity

 Step 1 Round the number of stores for each country to the nearest hundred thousand. Make a horizontal bar graph that shows the number of stores for each country. (See a sample horizontal bar graph on page 16 of your textbook.) Step 2 In the graph you made in Step 1, suppose a segment was drawn along the top of each bar. Which countries would have segments that are congruent? Explain. Step 3 Use the data in the table to find the average number of people per store for each country. (Do not round any of the values.) For example, what is the average number of people per store in China? Round each average to the nearest whole number. Step 4 Make a horizontal bar graph that shows the average number of people per store for the ten countries. Step 5 In the graph you made in Step 4, suppose a segment was drawn along the top of each bar. Which countries would have segments that are congruent? Explain.

Wrapping Up the Activity

Describe what you discovered about the number of people per store for the ten given countries. Make a conjecture about the types of countries that have the fewest people per store. Write a paragraph justifying your conjecture.
