For this section, you’ll need the Countries of the World Starter File open on your computer. If you haven’t already, select Save a Copy from the "File" menu to make a copy of the file that’s just for you. The columns in this dataset are described in the left column below:

  • country - name of the country

  • gdp - total Gross Domestic Product of the country. GDP is often used to measure the economic health of a country.

  • population - number of people in the country

  • pc-gdp - the average GDP per-person, in US Dollars

  • has-univ-healthcare - indicates if the country has universal healthcare

  • median-lifespan - the median life expectancy of people in the country

In Pyret, make a scatter plot showing the relationship between pc-gdp and median-lifespan, and sketch it below.

An empty graph for sketching on

1 What do you Notice about the point cloud?

2 What do you Wonder about the point cloud?

3 Do you see a relationship? If so, describe it (e.g. - linear or nonlinear? Strong or weak?)


4 Find the point for Equatorial Guinea, an outlier with pc-gdp = $38,058 and median-life-expectancy = 65. Why might this point be so far from the rest?


5 Find the point for Japan, another outlier with pc-gdp = $43,030 and median-life-expectancy = 85.5. Why might this point be so far from the rest?


6 Are there any countries that stand out? Why or why not?

7 Suppose a wealthy country is suffering heavy casualties in a war. Draw a star on the scatter plot, showing where you might expect it to be.
