There
are three main elements in a graph :
-**
a vertical axis** (the y- axis)
-** a horizontal
axis** (the x-axis),
- at least one **line**
or set of **bars.**
To understand a graph,
do the following:
1 Read the title of the
graph.
2 Read the labels and
the range of numbers along the side (the scale or vertical axis),
and the information on the bottom (horizontal) axis.
3 Determine what units
the graph uses. This information can be found on the axis or in
the legend.
4 Look for patterns,
groups and differences. |
