1. Graphing
1-3

2. Objective Create and analyze graphs based on numerical data.
CLE 3202.Math.1 Understand the mathematical principles behind the science of physics.

3. Graphs
Used to show numerical information in a useful format.

4. Each Graph must include:
Title
Units for each axis
Label for each axis
Scale
Data

5. Example:
Graph Title
Data
Y Axis
X Axis

6. Variables
Independent variable = X axis
Dependent variable = Y axis

7. Three Main Types
Bar Graph
Line Graph
Circle (Pie) Graph

8. A. Types of Graphs
Bar Graph
Shows
information
collected by
counting

9. Bar Graph
Data
Ex:

10. Bar graph: used to compare quantities in different categories

11. A. Types of Graphs Line Graph
shows the relationship between 2 variables
Dependent Variable
Independent Variable

12. Line graph: used to show change over time

13. Line Graph
Continuous Change

14. Circle (Pie) Graph
Percentages

15. A. Types of Graphs Pie Graph Shows distribution of parts within a
whole quantity

16. Used to show how a part relates to the whole
Pie Graph:
Used to show how a part relates to the whole
Needed to show percentages effectively
