"Diversity of population" should be "diversity of community" since a population refers to one species - therefore, a measure of species richness cannot be applied to a population and instead must be applied to a community of species. 220.127.116.11 (talk) 17:08, 7 January 2010 (UTC)
"A diversity index is a quantitative measure that increases when the number of types into which a set of entities has been classified increases, and obtains its maximum value for a given number of types when all types are represented by the same number of entities"

Why does the definition of qD have the term p_i*p_i^(q-1), when this is simply equal to p_i^q? It seems these two p's may be slightly different, however this is not clear in the text. — Preceding unsigned comment added by Bbeckerman (talk • contribs) 21:51, 23 September 2013 (UTC)
