1. Graphing
For Biology

2. Why is Graphing Important In Science?
Graphing is used by scientists to display the data that is collected during an experiment.
When a graph is put together incorrectly, it detracts the reader from understanding the data you collected.

3. Most graphs contain 5 major parts
1. Title - describes what the graph is about and tells the reader what to expect
2. X-axis - depicts the independent variable that can be controlled by the experimenter
3. Y-axis – depicts the dependent variable that is affected directly by the independent variable
4. Scaling for each variable – scaling/numbering must be consistent and must take up a conservative amount of space
5. Legend – short descriptive narrative concerning the graph’s data

4. Types of Graphs Bar Graphs – used to compare amounts
Line Graphs – used to show the change of one piece of information as it relates to another change

5. Bar Graph Example What is the independent variable?
What is the dependent variable?
What is the appropriate title?
What is the average number of deer per month?
