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

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.

Let’s Try It. Water Temperature (*C) Number of Developing Clams 15 75 20 90 25 120 30 140 35 40 45 50

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?

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

Analyzing Graphs What is the independent variable? What is the dependent variable? Which area has more elephants? Which animal is least populous regardless of location?

Analyzing Graphs…ANSWERS What is the independent variable? Type of animal What is the dependent variable? Number of animals Which area has more elephants? Karnataka Which animal is least populous regardless of location? Tigers
