This module from the Food and Agriculture Organization of the United Nations (FAO) demonstrates a range of ways to measure inequality by using the statistical concepts of location, shape and variability.
The guide illustrates with step-by-step examples the following measures: the range; the relative mean deviation; the variance; the coefficient of variation; and the standard deviation of logarithms.
