In this activity, students are given a data set that compares the salaries of men and women over a period of years and asked to determine if women's salaries will ever be equal to those of men. The activity, part of the Figure This! collection of 80 online challenges emphasizing real world uses of mathematics, explains how data interpretation is important in such industries as advertising, athletics, and insurance. It suggests that students approach the problem by using fractions or difference to compare the salaries and then looking for trends. The exploration also has activities to investigate percent increase and extrapolation. Questions are posed to encourage students to think about factors that might affect trends in salaries, as well as factors that might cause women's salaries to be lower than men's. Additional pages contain a solution hint, the solution, related math questions, and resources for learning more about income and data. Copyright 2005 Eisenhower National Clearinghouse
