Use the data in the preceding exercise to calculate the percentage change in government saving and the percentage change in GDP each year from 1990 through 2010. When you calculate the percentage change from a negative base, divide by the absolute value of the base. For example, the percentage change in saving from 1990 to 1991 is 100*(–301.3 – (–251.8))/abs(–251.8) = –19.6%. Make a scatterplot of these percentage changes and write a brief paragraph summarizing this graph.
