Can you help? Besides his extensive derivative trading expertise, Adam is an expert in economics and behavioral finance. Thus for your sample of 10 for your second, third, fourth and fifth graphs, the graph should show a series of 10 steps like a bar chart and not a slope. To elaborate even more on this if I take your example about the village with the 10 people I can find out total income and population but can not find out income distribution can I still do it? Confusing. The Gini Coefficient is calculated as follows. Thanks for a good basic explanation, but when you have a small number in your population, the data does not even come close to approximating to a continuous function, but is instead a series of clearly discrete steps. o Scale independence: the Gini coefficient does not consider the size of the economy, the way it is measured, or whether it is a rich or poor country on average.
