Parts of a bar graph.
Bar graphs are an excellent way to show results
that happen one time. It is an easy comparison
tool for surveys, inventories, and this type of
data. The bar graph is marked off with a series
of lines called grid lines. Bar graphs can be
horizontal or vertical. Both kinds will have two
axes. One axis gives the frequency information
and the other axis gives the group data. Bar
graphs must also have a title and labels on the
axes.

Activity Example
Favorite Subjects in our Class
Gather data to determine which subject is the
favorite amongst your classmates, or school. The
total number of responses will affect the size of
your bars. Determine what the frequency numbers
will need to be from the responses. This graph
represents 30 responses. 5 liked Science, 4
liked reading, 6 liked math, 3 liked English, 7
liked spelling and 5 liked Social Studies. It is
easy to see the spelling is the favorite subject
while English is the least favorite.
