This eighth-grade worksheet prompts students to interpret the slopes and y-intercepts of lines of best fit in real-world situations. In scatter plots with a linear association, the line of best fit (also referred to as the trend line) is the line that most accurately represents the data. The two-page practice worksheet provides students with scatter plots containing genuine data, and the line of best fit is given for each plot. Students are tasked with writing the equation for the line of best fit and interpreting the slope and y-intercept within the context of each scenario. This worksheet is an effective approach to improve students' data analysis skills and prepare them for advanced statistics courses. To learn more about lines of best fit, students can try the Estimating Lines of Best Fit worksheet.
