Biodiversität ) entwickelt und ist neben … Lastly, we can use the following formula to calculate Simpson’s Index: D = Σni(ni-1) / N(N-1) Using the values we found earlier, Simpson’s Indexcan be calculated as: D = 2,668 / (105*(105-1)) = 0.244. We can also calculate Simpson’s Index of Diversity as 1 – D = 1 – 0.244 = 0.756. We can also calculate Simpson’s … Visa mer Suppose a biologist wants to measure the diversity of species in a local forest. She collects the following data: Visa mer Next, she can calculate ni(ni-1).
