 Graphs display data so that it can be easily understood. You can use graphs to compare sets of data.

The students in Mrs. Carroll's class surveyed the school parking lot and made a graph to compare the data.

 Cars in the School Parking Lot Color Number Silver 12 Blue 8 White 5 Black 10 Red 7 Other 15

The data was organized in a table  making it easier to read and interpret. The data from the table can be used to create the following bar graph and pictograph.

A pictograph uses pictures or symbols to represent different numbers of the same item. The key tells how many each symbol stands for.
