Algebra I Module 2, Topic D, Overview

Work Group

In Topic D, students analyze relationships between two quantitative variables using scatterplots and by summarizing linear relationships using the least squares regression line.  Models are proposed based on an understanding of the equations representing the models and the observed pattern in the scatter plot.  Students calculate and analyze residuals based on an interpretation of residuals as prediction errors.
