Which term describes a diagram in which numerical values are represented by the height or length of lines or rectangles of equal width?

• A. Line graph
• B. Pie chart
• C. Time and a half
• D. Bar graph

Answer: (D)

Bar graphs represent numerical values by the height (or length) of bars that all have the same width. This description fits the diagram in question, where each category is shown with a rectangular bar and the value is conveyed by how tall or long that bar is. This makes it easy to compare amounts across categories at a glance. This differs from a line graph, which uses points connected by lines to show how values change over time or another continuous variable; a pie chart shows parts of a whole as slices of a circle; and the term time and a half isn’t related to chart types at all. Bar graphs are ideal when you want to compare distinct categories side by side.
