A line chart would be an appropriate format for displaying changes in a continuous, interval-ratio level variable such as the U.S. divorce rate over time. A histogram is more appropriate for displaying distributions of a variable, but not as useful for tracking changes over time. A pie chart is not appropriate for displaying changes over time, as it is better for displaying proportions of categories within a single time period. The last option is incorrect, as data in the form of rate can be displayed in a chart or graph.
