• 1. Describing Variables in a Bubble Graph about Religiosity

The graph shows the data from a Gallup survey relating religiosity to gross domestic product (GDP) per capita. GDP is the market value of the goods and services produced by a country over a certain time period, usually by year. It is often used as a comparative statistic to gauge a country's standard of living. Describe the variables displayed in the graph.

• Worked-Out Solution

Here are the variables.

• Each bubble represents a country.

• The vertical axis measures the percent of the population who say that religion is an important part of their daily lives.

The higher the bubble, the greater the number of people who say that religion is an important part of their daily lives.

• The horizontal axis measures the GDP per capita. The farther to the right, the greater the GDP per capita.

• The area of the bubble measures the population size. The bigger the bubble, the larger the population.

• The color of the bubble represents the dominant religion in the country.

• 7. Comparing Countries with High GDPs per Capita

The graph shows the data from a Gallup survey relating religiosity to gross domestic product (GDP) per capita. GDP is the market value of the goods and services produced by a country over a certain time period, usually by year. It is often used as a comparative statistic to gauge a country's standard of living. Compare the religiosity of the United States with that of other countries with high GDPs per capita.

• Worked-Out Solution

The United States is one of the few countries with a high GDP per capita and a high percent of people who say that religion is an important part of their daily lives. The majority of the countries with a high GDP per capita have a low percent (less than 50%) of the population who say that they are religious. In this sense, the United States is an outlier.
