2.  Line Graphs: are used to show something changing over time.  Bar Graphs: are used to show a comparison between two or more variables.  Pie Chart: are used to show a part of the whole (100%).

3. 1. Title 2. Both axes are numbered and have an equally spaced scale interval. a. Example: 1 box = 10 degrees Kelvin 3. Both axes are labeled. a. Example: X axis = Months Y axis = Degrees in Kelvin 4. If you have more than one line or several bars on the same graph, you need to have a legend that explains what each color represents. a. Example: Red Line = Temperature in High Point, NC Blue Line = Temperature in Greensboro, NC

4.  Independent Variable is ALWAYS on the X AXIS.  Dependent Variable is ALWAYS on the Y AXIS. **The Independent Variable causes a change in the Dependent Variable and it is NOT possible that the Dependent Variable could cause a change in the Independent Variable.**

5.  The amount of time that you study for a test will affect your test score.  Your test score will not affect the time that you study. So…. The time you study = Independent Variable (X Axis) The score on your test = Dependent Variable (Y Axis)

6. Title: Student Success X Axis: Hours Spent Studying Y Axis: Average Test Score X Axis Scale: 1 box = 1 Hour Y Axis Scale: 1 box = 10 Points on the Test
