The use of the Gini index in Design of Experiments is unexplored. Wepresent here some connections between the aberration of a fractional factorial designand the Gini concentration index of its fraction terms. In fact, both the aberrationand the Gini index depend on geometrical properties of the fraction. The main toolin our theory is the indicator function of a fraction.
