1. Types of Graphs and Graphing Rules
Unit 1

2. Types of Graphs
There are three types of graphs that we will use in this class:
Line Graphs
Bar Graphs
Pie Graphs

3. Line Graphs
These graphs are used to show continuous change, usually over time
For example, you might want to show the progress of something over a period of time

4. Bar Graphs
These graphs are used to show a comparison between data or between different IVs
For example, when comparing the number of students who like various types of fruit

5. Pie Graphs
These are used to show the different parts or percentages of a whole
For example, the percentages of students at Wagner who are involved in the various clubs and those who are not

6. Graphing Rules All graphs must have a Title
Usually in the form of “The Effect of the IV on the DV”
All axes should be labeled with titles and the units of measurement
All integers along each axis should be spaced equally and full use made of the entire graphing space

7. Graphing Rules
The independent variable is graphed along the horizontal X-axis
The dependent variable is graphed along the vertical Y-axis
Always provide a key or legend when graphing more than one set of data

8. On the Axes below
Attach the labels to the appropriate place on the graph
