Using
Statistical Regression to Investigate Track and Field Records 

 
Regression equations are used to investigate world records from the world of track and field. Mathematics: Data, scatterplots, modeling, and regression equations Mathematics
Thinking:
Students will model
data, using regression equations.
Students will discuss the strengths and weaknesses of the model and
make predictions about future world records. Technology:
Students
will use the TI83Plus to analyze data.
This lesson assumes students are familiar with the statistical
features of the TI83Plus Below are some sample screen shots of the TI83Plus calculator. Screen
shot of the lists
Screen shot of the scatterplot
Screen shot of a regression equation along with the scatterplot
