Interpreting Slope and Intercept of Line of Best Fit
This activity takes you from the basics of equations of lines (slope and intercepts) to scatter plots and lines of best fit. Interpret the slope using the context of the problem and use the regression line to extrapolate values. Included in the detailed lesson plans are a warm-up activity and a link for pre-lesson review on slopes of lines.

Scatter Plots and Line of Best Fit – TV Task
This handout begins by asking your statisticians to form hypotheses on the correlation between test scores and student height and test scores and the number of hours watching TV. Then using specific data, your class will create scatter plots, find the line of best fit, calculate correlation values, and discuss the possibility of causation based on their findings.

Linear Modelling of the Life Expectancy of Canadians
Middle and high schoolers explore the concept of linear modelling. In this linear modelling lesson, pupils find the line of best fit for life expectancy data of Canadians. They compare life expectancies of men and women, and find the point of intersection when males and females have the same life expectancy.
