Description
What It Is:
A graphing worksheet where students create scatter plots from two sets of data and draw a line of best fit for each graph. Each problem includes a data table with x–y values and a blank coordinate grid where students plot the points. After graphing, students analyze the trend and write an equation or description of the line of best fit. This worksheet supports early introduction to statistics and data modeling.
Why Use It:
This activity builds foundational skills in interpreting real-world data and understanding linear relationships. Students learn how to visually identify trends, estimate a line of best fit, and explain how the line models the relationship between variables. These skills directly support later work with correlation, linear regression, prediction, and function modeling in Algebra and Statistics.
How to Use It:
• Have students plot each ordered pair accurately on the coordinate grid.
• Ask them to sketch a line that best represents the overall trend of the plotted data.
• Students then write a line of best fit—either as an equation or a descriptive statement.
• Discuss whether the relationship is positive, negative, strong, or weak.
• Use for guided practice, independent work, or introduction to data analysis and modeling.
Grade Suitability:
Best suited for Grades 6–10.
• Ideal introduction to scatter plots in middle school.
• Supports Algebra I concepts of linear modeling and interpreting data trends.
Target Users:
Teachers, tutors, and students learning how to graph scatter plots and determine lines of best fit for basic data sets.
