For an accurately constructed Lorenz curve [1]

The vertical axis should be labelled cumulative % of income, or % of income and the horizontal axis should be cumulative % of population or % of population. A title is not necessary.

{correct points: (0,0); (20, 6.20); (40, 17.00); (60, 31.80); (80, 52.40); (100,100)}

Examiners report

The majority of candidates earned full marks for this question. There were some labelling errors such as "wealth distribution" or the omission of the percentage sign while a small number of candidates plotted data incorrectly by neglecting to calculate cumulative data.
