1. Graphing Data

2. Why Do We Use Graphs? Graphs help us visualize numerical data.
There are several different types of graphs:
Bar graphs
Pie graphs
Line graphs

3. Bar Graphs
Bar graphs are used to show a comparison of multiple objects.

4. Pie Graphs
Pie graphs are used to compare the parts of a whole.

5. Line Graphs
Line graphs are used to show the relationship between variables, particularly TIME

6. Types of Relationships (between variables)
Direct: as x increases y increases
Indirect: as x increases y decreases
Constant: as x increases y remains the same

7. Axes of a Graph: X-axis (horizontal axis) Horizontal means:
Y-axis (vertical axis)
Vertical means:

8. Label the x and y axes

9. Label the x and y axes Y-Axis Dependent Variable
X-Axis (Independent Variable)

10. Scale
Now you need to select evenly spaced intervals that include all your data (a scale).
Data set 1: 15, 30, 45, 7, 64, 95
Minimum value for scale:____
Maximum Value for scale:____

11. Scale
Now you need to select evenly spaced intervals that include all your data (a scale).
Data set 1: 15, 30, 45, 7,
Minimum value for scale:__7_
Maximum Value for scale:_95_
