Question: 1 / 400

What is the primary use of a bar graph?

To show trends over time

To compare quantities

A bar graph is primarily used to compare quantities across different categories. It visually represents data with rectangular bars, where the length or height of each bar corresponds to the value it represents. This allows for easy comparison between different sets of data, making it clear how each category stacks up against others.

While other options may reflect different forms of data representation—such as line graphs for trends over time, pie charts for parts of a whole, or scatter plots for relationships in data—they do not serve the primary function of a bar graph. The strength of a bar graph lies in its ability to provide a straightforward visual comparison, making it an effective tool for evaluating quantities side by side.
