Webb1 jan. 2015 · The Shannon-Weaver diversity index is one widely used index for comparing diversity between various habitats (Clarke and Warwick, 2001 ). It assumes that individuals are randomly sampled from an independent large population, and all the species are represented in the sample (Shannon and Weaver, 1949 ). WebbShannon’s Diversity Index Basic Concepts For categorical data, there is no mean or median and so we can’t use the measures of variation described in Measures of Variability. Instead, we use a measure of the distribution of observations among the categories.
