Quizplus · Accepted Answer

A time-series graph displays data over time, and therefore reveals whether there is a trend in a variable (i.e. whether there is a general tendency for the variable to rise or fall). It does not necessarily show a relationship between two variables (as in choice A) or trends in two variables (as in choice B). It also does not show a cross-section relationship (as in choice C) - this would be more suited to a scatterplot or other type of graph.
