FAST FACTS ABOUT BAR GRAPHS

EVERY BAR GRAPH HAS:

• a title

• two sides (the vertical and horizontal axes)

• descriptive labels for each side (or axis)

• a scale calibrated to suit the data (by 1s, 2s, 5s, 10s, 25s, etc.)

FACTS:

Bars can be vertical or horizontal.

The tallest bar represents the greatest amount; the shortest bar corresponds to the least amount; bars that represent identical quantities are the same length.

Bars may touch or be separated.

Double bar graphs compare two related sets of data on one graph.
