A graph that uses pictures or symbols to show data.

• A. picture graph
• B. pictograph
• C. line plot
• D. bar graph

Answer: (B)

Using pictures or symbols to show data helps you read quantities at a glance. In a pictograph, each picture represents a certain number of items, and a key tells you exactly how many. To find totals, you count how many pictures are in a category and multiply by the value each picture stands for. For example, if one picture equals 2 students and you see 6 pictures in a group, that group has 12 students. This setup makes comparing groups quick and clear because you can see the difference by simply counting pictures. This differs from a line plot, which places data points on a number line with marks to show exact values, and from a bar graph, which uses bars of varying height to compare quantities without relying on pictures as the representation. A picture graph is a closely related idea, but the term that specifically describes a chart using pictures or symbols to represent data is pictograph.
