Statistics Activity: Scatterplots and Regression

Statistics Activity: Explore scatterplots and linear regression using M&M™ candy

In this activity, students will measure their hand span and then grab a handful of M&Ms. They will explore this linear relationship using scatterplots, the least-squares regression line, and the correlation.

This activity can be used with your AP Statistics or regular level statistics class. These are the following skills covered:

Math Common Core Standards, High School: Probability and Statistics

• Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. (ID.B.6)
• Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data. (ID.C.7)
• Compute (using technology) and interpret the correlation coefficient of a linear fit (ID.C.8)

AP Statistics Course Exam Description

• UNC-1.S Represent bivariate quantitative data using scatterplots
