Part 1
One of the changes that have occurred in recent decades is an increase in the number of women with careers. There has also been an increase in the number of women with higher academic and vocational qualifications. However, there is still a large difference between the earnings of men and women. Using the data from the SURF for Schools dataset, investigate why this may be?
You will need to:
Problem – state the problem.
Plan – outline how the investigation can be carried out.
Data – look for appropriate variables to use and check that it is clean.
Analyse – graph the variables, look at their relationships and do the appropriate calculations.
Conclusions – what does the analysis suggest and does it answer the problem?
Part 2
Just analysing the whole dataset might give a misleading result. There may be some differences due to women having higher qualifications than in the past. Investigate the earnings of men and women in two different qualification categories.
You will need to:
Problem – state the problem.
Plan – outline how the investigation can be carried out.
Data – look for appropriate variables to use and check that it is clean.
Analyse – graph the variables, look at their relationships and do the appropriate calculations.
Conclusions – what does the analysis suggest and does it answer the problem?
Part 3
Are there any other factors that may affect earnings? Often differences occur because of hidden variables. For example, people working part time will have a smaller weekly wage, or age may be a factor in what people earn. Redo the investigation in part 2, taking into account a factor from the dataset that you think may be useful. You can use one of the ones mentioned or your own choice.
