Question

Quizplus · Accepted Answer

A time-series graph is the best choice because it shows changes in an economic variable over time, allowing for easy identification of trends and patterns. A scatter diagram is used to show the relationship between two variables, a linear graph shows a relationship between two variables in a straight line, a cross-section graph displays data for a single point in time, and a Venn diagram shows the relationship between sets of data. None of these options are as effective at illustrating changes in an economic variable over time as a time-series graph.
