Description:

In this activity, students click on a coordinate plane to plot points and view the best-fit line for those points. Students can also adjust their own fit line to test their skills at predicting the best-fit line. This activity allows students to explore linear regression and the correlation coefficient, r. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.

CCSS.Math.Content.8.SP.A.1: Common Core State Standards for Mathematics

Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.

CCSS.Math.Content.8.SP.A.2: Common Core State Standards for Mathematics

Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.

CCSS.Math.Content.HSS-ID.B.6a: Common Core State Standards for Mathematics

Fit a function to the data; use functions fitted to data to solve problems in the context of the data.

CCSS.Math.Content.HSS-ID.B.6b: Common Core State Standards for Mathematics

Informally assess the fit of a function by plotting and analyzing residuals.

CCSS.Math.Content.HSS-ID.B.6c: Common Core State Standards for Mathematics

Fit a linear function for a scatter plot that suggests a linear association.
