Math TODAY - Wildfire Deaths
 


Activity Overview

Students will be asked to use the "Wildfire deaths" data to determine a linear model. They will examine the effect an outlier has on the model and compare methods to determine the best model.

Before the Activity

If you are using the TI-Navigator™ System with the TI-73 Explorer™ you will need the attached .pdf file.
See the attached Teacher Edition PDF file for notes and guidelines for this activity. The Technology Guide PDF file includes step-by-step calculator instructions with screen shots. If you are using the TI-Navigator™ Classroom Learning System, see the TI-Navigator Basic Skills Guide PDF file for information on how the system can be integrated into your activity.

During the Activity

Students will:
  • Create a scatter plot.
  • Determine a linear equation using linear regression both with and without the outlier on the calculator.
  • Determine a linear equation using median-median both with and without the outlier on the calculator.
  • Compare the two sets of lines and determine which method is better when there is an outlier in the data set.


    • Directions:
  • Distribute the Student Edition PDF file to your class.
  • Follow the activity procedures outlined in the student document.
  • You may use the Transparency PDF file to display a large image of the USA TODAY® graphic during the activity.
