1. Creating Graphs

2. Types of Graphs Line Graphs Compare two variables
Show trends and relationships in data
Allow the viewer to make predictions
Bar Graphs
Visually represent a set of data
Pie Charts
Show part-whole relationships
Used mostly in statistics

3. Line Graph

4. Bar Graph

5. Pie Chart

6. Independent Variable
The factor that is varied in an experiment and specifically controlled by the experimenter
Located on the x-axis

7. Dependent Variable
The factor that is measured in an experiment and will change as a result of the independent variable
Located on the y-axis

8. On Paper
Using your data, identify the independent and dependent variables
Draw your graph, labeling the x- and y-axis
Title your graph
Choose your intervals based on your data
Plot your data

9. Practice-As a Class
Diabetes is a disease affecting the insulin producing glands of the pancreas.
If there is not enough insulin being produced by these cells, the amount of glucose in the blood will remain high.
A blood glucose level above 140 for an extended period of time is not considered normal.
This disease, if not brought under control, can lead to severe complications and even death.

12. Questions What is the dependent variable?
What is the independent variable?
What would you title the graph?
Which individual(s) has diabetes?

13. Practice-In Your Notes

15. Questions-Type in document
What is the dependent variable?
What is the independent variable?
What was the average thickness of annual rings for 40 year old trees in Forest A?
Based on the data shown, what can be concluded about the comparative health of Forest A & B?
What type of relationship (constant, direct, or indirect) exists between the age of trees and the average thickness of the tree’s rings? Explain.

16. On Google Sheets/Excel
Go to your Google Drive
Click “new”
Click “Google Sheet” in the drop down menu
Name your file
Enter your data (x-axis in the first column and y-axis in the next column)
Select your data
Click “Insert”
Choose the appropriate chart type based on the data
Make sure your graph has a title, legend, and axis labels
If not, right hand mouse click the graph to make the necessary changes

17. Graphing Practice Assignment
In google classroom, locate the In-class graphing practice assignment
Click on the assignment
Create a google sheet and title: In-Class Graphing Practice
Type in the data table (on the next slide)
Create the appropriate graph
You need to have a graph title, labeled axis, and a legend
You will submit this to google classroom after we are finished

18. Practice-As a class Open Google Sheets
Using the data, identify the independent and dependent variables
Input your data (independent in first column, dependent in second column)
Select the correct type of graph
Make sure the graph has a title, axis are labeled, and there is a legend
