How do you represent data using a line graph?

Representing data using a line graph involves plotting individual data points corresponding to specific values along a vertical and horizontal axis, and then connecting these points with straight lines. This method effectively displays trends over time, allowing viewers to easily observe the progression of the data. Each point on the graph represents a distinct value or measurement, and by connecting them, it becomes clear how the data changes at various intervals.

Line graphs are particularly useful when you want to show continuous data or how one variable influences another over time. This ability to visualize changes helps in identifying patterns, trends, and anomalies within the dataset.

The other options, while they describe different data representation techniques, do not accurately convey the essence of a line graph. For example, only using bar segments pertains to bar graphs, averaging data points before plotting is usually associated with methods like scatter plots or summarizing data, and illustrating categories without connections refers to pie charts or categorical graphs that don’t display relationships in a temporal context.
