Interpreting a Double-Bar Graph
Learning the Skill
II
Graphs allow you to look at statistical information in a visual way.
Bar graphs show information in bars, or wide lines. You can use a bar
graph to compare different items, or changes in the same item over
time. A double-bar graph compares two items, such as the number of
boys and the number of girls in each grade at your school. The bars
may be drawn either vertically or horizontally. Labels on the vertical
and horizontal axes tell you what the bars represent. A key tells you
what items are being compared.
Follow these steps to read a double-bar graph:
• Read the title to find the subject(s) of the graph.
• Study the information in the key and on the side and bottom of
the graph to find what the bars represent.
• Compare the lengths of the bars to draw conclusions about the
subjects of the graph.
Follow these steps to create a double-bar graph:
• Collect the statistical data you will need to make the double-bar
graph.
• Create a grid with horizontal and vertical axes. Label the axes.
• Decide how each axis will be divided numerically. Label each unit.
• Give the graph a title and a key.
• Using the statistics you researched, create bars that represent the
items being compared.
