This lesson, one of a nine-part unit from Illuminations titled “Interpreting the ‘Real-Life’ Meaning of Graphical Representations of Data,” is a third representation of the automobile mileage data used in Lessons Five and Six of this Unit Plan. This lesson provides another opportunity for the students to analyze how changing the independent variable in a set of data can result in a different least squares regression line. Students can then use the new equation to make some of the same predictions they made in Lessons Five and Six.

This lesson incorporates an interactive regression line applet.
