Contextualization
Scatter plots are a visual representation of the correlation (or the lack of it) between two variables. They are widely used in statistics, data analysis, and in a variety of realworld applications. They provide a quick and intuitive way to understand the relationship between two sets of data. Scatter plots consist of data points, where each point represents a different data value in the set. The position of the point on the x (horizontal) and y (vertical) axes represents its values in the two variables being compared.
The first part of our project will focus on understanding the theory behind scatter plots, their construction, and interpretation. We will delve into the concepts of positive, negative, and no correlation, as well as the idea of a line of best fit. A line of best fit is a straight line drawn through the data points that best represents the relationship between them.
In the second part, we will explore the realworld applications of scatter plots. We'll see how they are used in fields such as economics, social sciences, and even medicine to understand the relationship between two variables. For example, in medicine, scatter plots might be used to understand the correlation between the dosage of a drug and its effectiveness.
This project is designed to foster your understanding of scatter plots, their construction, and their realworld applications. It will also aim to develop your skills in data analysis, critical thinking, and problemsolving.
To begin this project, you'll need a strong foundation in basic algebra, as understanding the relationship between variables is key to understanding scatter plots. You'll also need a good grasp of geometry, as scatter plots are essentially a graphical representation of data.

Practical Activity
Activity Title: Scatter Plots in the Real World
Objective of the Project:
The primary objective of this project is to deepen your understanding of scatter plots, their construction, and interpretation. You will also explore the realworld applications of scatter plots and develop your skills in data analysis, critical thinking, and problemsolving.
Detailed Description of the Project:
In this project, you will have the opportunity to apply your knowledge of scatter plots to realworld data sets. You will create scatter plots, analyze the correlation (or lack thereof) between variables, and develop a line of best fit.
You will then use this analysis to draw conclusions about the relationship between the variables and make predictions based on your scatter plot and line of best fit.
Finally, you will write a detailed report documenting your process, findings, and conclusions.
Necessary Materials:
 A computer with internet access for data collection and analysis.
 Spreadsheet software (e.g., Google Sheets or Microsoft Excel) for data management and scatter plot creation.
 Notebooks and pens for brainstorming, planning, and documenting the project.
 A printer for printing the final report.
Detailed StepbyStep for Carrying Out the Activity:

Form your Groups:
 Divide yourselves into groups of 3 to 5 students. Each group will work together on the project.

Choose a RealWorld Theme:
 As a group, choose a realworld theme for your scatter plot. This could be anything from sports, entertainment, health, or the environment. Make sure you can find a data set that fits your chosen theme.

Collect Data:
 Collect a data set that contains at least 20 data points relating to your chosen theme. The data set should have two variables that you can compare using a scatter plot.
 Ensure you understand the context of the data and how the variables relate to each other.

Create your Scatter Plot:
 Enter your data into a spreadsheet and create a scatter plot. Your data points should be clearly visible and labeled on the scatter plot.

Analyze and Interpret your Scatter Plot:
 Analyze your scatter plot. Is there a positive correlation (as one variable increases, so does the other), a negative correlation (as one variable increases, the other decreases), or no correlation?
 Discuss and interpret your findings as a group.

Develop a Line of Best Fit:
 Using your scatter plot, draw a line of best fit. This should be a line that goes through the middle of your data points and represents the general trend in the data.

Make Predictions:
 Use your line of best fit to make predictions about the relationship between the variables. For example, if the line of best fit has a positive slope, you might predict that as one variable increases, so does the other.

Write your Report:
 Finally, write a report detailing your process, findings, and conclusions. The report should follow the structure of Introduction, Development, Conclusions, and Used Bibliography.
Project Deliverables:
At the end of the project, each group will submit a detailed report and a presentation.
The report should follow this structure:

Introduction: This section should provide context for your chosen theme, explain why it is important, and outline the objectives of your project.

Development: In this section, you should explain the theory behind scatter plots, their construction, and interpretation. Discuss the data set you chose and how you collected it. Detail the methodology you used to create your scatter plot and develop your line of best fit. Finally, present and discuss your findings.

Conclusion: Summarize your project, including your main findings and the conclusions you drew about the relationship between the variables in your data set.

Bibliography: Include all the sources you used for your research and to complete your project.
Your presentation should include:
 An overview of your chosen theme and data set.
 A discussion of your methodology and how you created your scatter plot and line of best fit.
 A presentation of your findings.
 A conclusion summarizing your project.
The report and presentation should complement each other, with the report providing more indepth information and the presentation providing a visual overview of your project.
