Which graphic uses horizontal or vertical bars to display data?

• A. Bar graph
• B. Pie chart
• C. Line graph
• D. Pictograph

Answer: (A)

Bar graphs display data using bars whose lengths are proportional to the values. They can be oriented horizontally or vertically, which lets you compare amounts across categories at a glance. The horizontal arrangement often places categories on the vertical axis, while vertical bars place categories on the horizontal axis. This format is built for quick, side-by-side comparisons. In contrast, a pie chart shows parts of a whole as slices, a line graph traces changes over time by connecting points, and a pictograph uses icons to represent units of data. So the graphic that uses horizontal or vertical bars to display data is a bar graph.
