A bar graph is a graph that uses bars to show data.
Bar length is important. The highest or longest bar has the most.
The smallest or shortest bar has the least or fewest. Every
bar graph has a Title at the top that tells you what the graph is
about.

Bar graphs may be vertical or horizontal.
Vertical means up and down. Horizontal means across or left to right.

In the bar graph below, you will see two different colored
bars. This is called a double bar graph. Double bar
graphs are used for comparing data.

Every bar graph has a Scale, which are the numbers listed on one
axis (side or bottom) of
the graph. In the graph below, the Scale (Number of Votes) is on the
horizontal axis. The other axis on the graph below lists the
Subjects and is called the vertical axis. Note: The Scale
could be switched around so that it would be on the vertical axis and then
the Subjects would be listed on the horizontal axis.

The horizontal double bar graph below uses a Scale of two.
This means the numbers in the Scale count by two (2, 4, 6, 8, 10 and so on).
Be careful when the bar ends between two numbers.

If the bar ends between 4 and 6,
then the answer is 5.

If the bar ends between 8 and 10
then the answer is 9.
