Mastering the Line of Best Fit: A Step-by-Step Math Lesson for Scatter Plots

Welcome to our math lesson on drawing a line of best fit on a scatterplot and identifying an approximate linear equation in slope-intercept form. In this video, we will walk you through the step-by-step process of creating a line of best fit for your scatterplot, and help you understand how to identify the equation for the line in slope-intercept form.

Whether you're a student or a teacher looking to enhance your understanding of this important math concept, our lesson is here to help.

Math Standards
Aligned with common core standards. Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line. Given a scatter plot with a linear association, informally fit a straight line. Descriptions include outliers; positive or negative association; strong or weak association. Florida's B.E.S.T. math standards: MA.8.AR.3.5 Problems include equations of lines of fit in scatter plots. MA.8.DP.1.3 Given a scatter plot with a linear association, informally fit a straight line. Instruction focuses on the connection to linear functions. Instruction includes using a variety of tools, including a ruler, to draw a line with approximately the same number of points above and below the line.
