In this activity, students will draw a scatter plot and a line. They will investigate the method of least squares by finding the residuals and the sum of the squares of the residuals. They will then test their line using the built-in linear regression model.

ResourceSpotlight
In this activity, students will assess the strength of a linear relationship using a residual plot. They will also calculate the correlation coefficient and coefficient of determination to assess the data set. Students will then learn to transform one or two variables in the relationship to create a linear relationship.
