A graph that uses horizontal or vertical bars to display data.

• A. line graph
• B. pictograph
• C. histogram
• D. bar graph

Answer: (D)

Bar graphs use horizontal or vertical bars to compare data across different categories. Each category has a bar whose height or length shows its value, and the bars are separated to make comparisons clear. This orientation lets you see at a glance which categories have more or less. The bars can be arranged vertically (bars rising up) or horizontally (bars extending to the right), but the key idea is the same: the size of each bar represents the quantity. This is different from a line graph, which shows how a value changes over time by connecting data points with a line. A pictograph uses pictures to represent quantities, often with repeated icons. A histogram shows the distribution of a dataset by grouping data into bins with touching bars that represent continuous data. The description fits a bar graph best.
