Lesson Plan: What Fits?
Anna Bargagliotti and Stephanie Casey
(Grades 6-12+) Originally published in February 2013, this activity has students explore what a line of best fit is and where a line of best fit should be placed on a scatterplot of data with a linear association. This is done through students’ completion of an activity investigating the relationship between the drop height of a golf ball and the height of its first bounce, as well as analysis of other students’ work on the same activity. Students will learn what the line of best fit means and appropriate criteria for its placement.
