What Are Scatter Plots?
INTRODUCTION/ BACKGROUND:
Over the next three days you will research and create scatter plots. Your final project will include a written definition for scatter plot. You will use data collected from class to create a set of scatter plots. Then using the scatter plots that you created, you will determine what kind of relationship exists between the sets of data. Finally, you will have two minutes of class time to present your project to the class.
TASK:
During your two-minute presentation to the class, you will show and explain your final project. The following are examples of good projects: poster, booklet, power point, imovie, CD cover with jacket, cartoon strip, 3-D display, story book, acting out a play, scrap book with journal entries, … You may choose the form your final project will take. The minimum contents of your project are listed in the process section.
PROCESS:
Step One:
Use the project guide and the following web sites to research scatter plots. The questions in the project guide will help you to successfully complete your final project.

Step Two:
Use the data we compiled in class to create three scatter plots of your choice. The following web sites will help you create your scatter plots.

Step Three:
Make your final project.
Minimum contents of your project are as follows:
1) A definition of scatter plot that includes:
A description of what scatter plots look like
What scatter plots are used for
Types of relationships that the graphs represent
What a correlation means
2) At least three complete examples of scatter plots made from the class data
Title your graph
Label the axies
List the coordinate points using set notation or a chart
Description of the correlation for each graph
3) A concrete item to hand in after your oral presentation
This item is the bulk of your project. It contains all the above information in a creative form of your choice.
4) Oral class presentation
Describe your project
Tell why you chose your project format
RESOURCES to help you go above and beyond the main requirements:
1) Here are additional web sites you may find helpful when creating and making your final project. These sites contain information that could enhance your project contents and help you to present information beyond the basic project requirements. These sites are for those individuals who wish to be pro active and add extra items and information to their presentation.

2) Create your own set of data to compare.
3) Draw the line of best fit for each graph. Write an equation for the line of best fit
for each graph you made in your project.
4) Make a prediction based on the data in each chart.
EVALUATION:
A total of 100 points maybe earned with this project using the rubric in your project guide.
