The Gini Coefficient
- Levels: AS, A Level, IB
- Exam boards: AQA, Edexcel, OCR, IB, Eduqas, WJEC
The Gini coefficient measures the inequality among values of a frequency distribution (for example levels of income).
A Gini coefficient of zero expresses perfect equality where all values are the same (for example, where everyone has an exactly equal income). A Gini coefficient of one (100 on the percentile scale) expresses maximal inequality among values (for example where only one person has all the income).
