Question: You are going to draw a scatter diagram, with 2006 GNI per capita (from Table 2.1) on the horizontal axis and the ratio of income received by the richest 20 percent to the share received by the poorest 20 percent (from Table 2.3) on the vertical axis.
a Plot the data for ten of the countries in the tables.
b Is there any systematic relation between GNI per capita and the degree of income inequality? Do countries with low levels of GNI per capita have more or less inequality than economies with higher levels of GNI per capita? (If you have access to Excel or a simple statistical analysis package, you could run a simple regression between the two variables to look for a relation.)
