Effect of Data Frequency on Trend Line Smoothness in Economic Charts

China's Atypical Economic Path During the COVID-19 Era

Consider a line chart that displays the Gross Domestic Product (GDP) per capita for two countries, Country X and Country Y, from 2009 to 2023. The data is presented as an index where the GDP per capita of the United States is set to 100 for each year, serving as a benchmark. On this chart, Country X's line begins at an index value of 85 in 2009 and gradually declines to 80 by 2023. Country Y's line begins at an index value of 25 in 2009 and steadily rises to 40 by 2023. Based solely on this information, which of the following statements provides the most accurate analysis of the economic trends?

On a line chart showing various countries' GDP per capita as a percentage of the U.S. GDP per capita (where U.S. = 100 for each year), a country's line trends downward from 95 to 90 over a five-year period. This downward trend necessarily indicates that the country's own absolute GDP per capita has decreased during that time.

Interpreting Relative Economic Growth Data

Analyzing Economic Convergence and Divergence

An economist is analyzing a chart that shows the GDP per capita of several countries from 2010 to 2020, indexed to the United States' GDP per capita (U.S. = 100 for each year). Match each described trend on the chart to its most accurate economic interpretation.

Evaluating Relative Economic Performance Metrics

A line chart displays the GDP per capita of Country Z indexed to that of the United States, where the U.S. value is set to 100 for each year. In a particular year, the absolute GDP per capita of the United States grew by 4%. During that same year, the line representing Country Z on the chart remained perfectly horizontal. This means that Country Z's own absolute GDP per capita must have grown by ____%.

An economic analyst is studying a chart that shows the GDP per capita of four different countries (A, B, C, and D) from 2010 to 2020. The data is indexed, with the GDP per capita of a benchmark country set to 100 for each year. Based on the starting and ending index values provided below, arrange the countries in order from the one that showed the most positive change in its economic performance relative to the benchmark country to the one that showed the most negative change.
