| Description: | This activity opens with a graph that depicts the life expectancies of men and women born in the United States. Students are asked to estimate the greatest difference between genders in the years between 1920 and 1996. The activity, part of the Figure This! collection of 80 real-world math challenges, introduces trend analysis and explains its utility to market research, radio stations, and manufacturers. The Hint tells students how they should read the graph to determine the life expectancy for a woman born in 1920. Related questions encourage students to think about how the shape of the curve might be affected by changing the scale, as well as variables that affect trends in life expectancy. Answers to all questions and additional resource suggestions are provided. Copyright 2005 Eisenhower National Clearinghouse |
