4. Graphing Notes Graphs are a way to display data or results
Good graphs contain five parts
Title: Tells what the graph is about. Concise statement placed above or below the graph
Independent Variable: Always found on the X (or horizontal) axis

5. Good graphs contain five parts
Dependent Variable: Always found on the Y (or vertical) axis
Scale: axis must be labeled and numbered in an consistent way; each line on the same axis must have the same value.
Key/Description: A brief explanation of parts of the graph readers may not understand as needed.

Number of Developing Clams 15 75 20 90 25
120 30
140 35 40 45 50

7. Graph Analysis What is the dependent variable?
What is the independent variable?
What is the relationship between water temperature and clam development?
What is the BEST temperature for clams to develop?

8. Graph Analysis…ANSWERS
What is the dependent variable? Clam Development
What is the independent variable? Water Temperature
What is the relationship between water temperature and clam development? Clam development increases as temperature increases until it gets too hot. Then clam development decreases.
What is the BEST temperature for clams to develop? 30*C
