Equal Pay?

In a recent issue, Parade Magazine discussed the disheartening effect of the 1963 Equal Pay Act, in that women still make about 78 cents for every dollar earned by a man.

Look at this interesting data from the U.S. Census Bureau:

  • In the 15-24 age group, the average salary of a woman is $23,357 and a man is $26,100
  • In the 25-44 age group, the average salary of a woman is $41,558 and a man is $55,286
  • In the 45-64 age group, the average salary of a woman is $44,808 and a man is $67,040
Task 1: Try to locate data for average salaries for women and men at the start of each decade (1900-2000) and determine if any progress has been made.

Task 2: Assuming a linear relationship, use the first two age-ranges to predict the salaries (and gap) for the third age-range. Good or bad fit?
