Skills resources are shared. Check your qualification page for its specific assessment conditions.
Gini coefficient
Use G = Σi Σj |xi − xj| ÷ (2n Σi xi), including both ordered pairs and zero self-differences. All incomes are non-negative. This is the uncorrected finite-population coefficient on a 0–1 scale; alternative small-sample corrections produce different values.

Five equally weighted fictional households
Use the resource carefully
State the unit and the part of the resource you used. A pattern in a fictional dataset is evidence for that exercise; it does not establish a fact about a real place.
Check whether an explanation is supported by the data or needs additional geographical knowledge. For statistical tasks, a calculated result does not establish causation or significance by itself.
