Question

Quizplus · Accepted Answer

A time-series graph is specifically designed to show changes in a variable over time, making it the ideal choice to demonstrate how an economic variable changes from one year to the next. Linear graphs are useful for showing trends, but not specifically changes from one year to the next. Venn diagrams and scatter diagrams are not appropriate for showing changes in economic variables. Cross-section graphs show data at a single point in time, rather than changes over time.
