DATA ANALYSIS

This data from Statistics Canada relates to the average of income of males and females across all of Canada. Compare the changes in male and female wages from 1976-2006 listed in the table below. (All dollar values are given in 2016 dollars, meaning that they have been adjusted for inflation).

Table 1: Male and Female Average Wages from 1976-2006

Year / Average wage (2016 $)
MALES / Average wage (2016 $)
FEMALES / Male Wage/
Female Wage
1976 / 55,400 / 29,600
1981 / 52,600 / 31,900
1986 / 51,500 / 33,000
1991 / 50,700 / 34,200
1996 / 49,700 / 34,200
2001 / 54,300 / 36,900
2006 / 55,200 / 39,000

Analysis:

  1. Using the grid providedbelow, plot the dataof male and female wages vs time (year). Don't forget to add a title,axes labels, and 2 lines of best fit for males and females.
  2. Complete the missing column in the table by calculating the ratio of male wage to female wage for each year listed from 1976 – 2006.
  3. In which year did males earn the most? The least?
  4. In which year did females earn the most? The least?
  5. In which year was the discrepancy between male and female wages the highest? In which year was it the lowest?
  6. What is the trend in income for males?
  7. What is the trend in income for females?
  8. What is the trend in the ratio of male wage to female wage? Explain what this represents in terms of equality of pay for males and females.
