Activity Overview
In this activity, students analyze statistical data using the calculator and the TI-InterActive!™ software. They perform regression on the data to find the life expectancy of people in Canada.
Before the Activity
Download the TI Connect™ software to transfer data from the computer to the calculator Link the TI Connect to the calculator Install the TI InterActive! on the computer Print pages 1 - 3 from the attached PDF file for the class
During the Activity
Distribute the printed pages to the class.
Follow the Activity procedures:
Download a Canadian Life Expectancy data table into the TI-InterActive!'s data editor
Name the lists and copy the list tables into a document
Export the data from the computer to the calculator
Plot a graph of life expectancy versus years [on the calculator or on TI-InterActive!]
Perform a linear regression [on the calculator or on TI-InterActive!] and find a line of best fit for the average life expectancy for males and for females
Use the graph editor to include the best fit line on the graph
Based on the regression line, determine the year in which the Canadian Life Expectancy will be 100
