WebbShannon-Wiener Index is defined and given by the following function: H = ∑ [ ( p i) × l n ( p i)] Where −. p i = proportion of total sample represented by species i. Divide no. of individuals of species i by total number of samples. S = number of species, = species richness. H m a x = l n ( S) = Maximum diversity possible. WebbThe index of diversity (also referred to as the Index of Variability) is a commonly used measure, in demographic research, to determine the variation in categorical data. The most common index of diversity measure was created by Gibbs and Martin (Gibbs, Jack P., and William T. Martin, 1962. “Urbanization, technology and the division of labor.”
