How can I compare different Simpson
WebbSimpson index is considered more as a dominance index as it accounts proportion of species in a sample. Whereas, Shannon-Weiner index is based on randomness present at a site and considers both species richness and equitability in distribution in a sample. How do you calculate Simpson’s Diversity Index in Google Sheets? WebbSimpson's (and Shannon's) have an important drawback as the values are not directly comparable. Firstly, because they are unitless, it makes the comparison challenging. WebbCalculate Simpson's Index, Shannon-Weiner Index, and the Evenness Index for waterbirds on two lakes: Lake A, and Lake B. There are 5 species and 25 individuals on both lakes, but are they equally diverse? Here are the solutions: Note that Simpson's Index is often expressed (1-D), so the final answers are 0.29 and 0.8. definition of ambulant
