Hi. I'm trying to help my cousin study for her AS econ, but my econ skills are very rusty. She has a past paper, but we couldn't find the mark scheme for it. The question we're stuck on is this:
The table below shows the mean and median weekly earnings for selected workers in the health sector:
Total employees Median weekly pay Mean weekly pay
Doctors 242 000 £1038 £1203
Nurses 844 000 £533 £522
a) Using a supply and demand diagram(s), explain
why it might be that doctors have higher average
weekly earnings than nurses.
b)Explain a possible reason why the median weekly
earnings for doctors are lower than the mean
weekly earnings.
@free2write,
We got the second part: If the median is less than a mean, the weekly earnings distribution has a positive skew, meaning that more doctors receive weekly earnings that are below £1203, with a smaller number earning higher weekly salaries.
Still need help with part A, though. Thank you!
