Q: "Simpson Index" can be loosely applied to 3 different values (and calculations) depending on the author/source: Simpson's Index, Simpson's Index of Diversity and Simpson's Reciprocal Index. This should be clarified. (section: 3/ paragraph: b/ sub-paragraph: iv/ line: 2)
A: Students should be familiar with all three. If used for the National competition the national supervisor will specify which is being used. We have chosen to define the Simpson index, p as the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), Σ is still the sum of the calculations, and s is the number of species. This information can be found on the files distributed at coaches clinics and will also be on the SO website once the clinics are over.
