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
Students will model
data, using regression equations.
Students will discuss the strengths and weaknesses of the model and
make predictions about future world records.
will use the TI-83Plus to analyze data.
This lesson assumes students are familiar with the statistical
features of the TI-83Plus calculator.
Below are some sample screen shots of the TI-83Plus calculator.
