(Solved): 1. Now calculate the Simpsons Diversity Index for Dive Site B: D = ?2. One index value on its own ...

$N=\text{ the total number of all individuals }$ Let's look at an example of how we use the Simpson's Diversity Index, using data from Belize, where ecologists are studying the biodiversity of tropical reef fish. The table below shows the number of individual reef fish species identified at two dive sites, A and B. Then, the components of the Simpson's Diversity Index are determined and tabulated as well. To complete the calculation of the Simpson's Diversity Index (SDI), we simply plug in the variables of the SDI formula. Below shows the calculation of the SDI for site A: $D=1?\frac{608}{43\times 42}D=1?\frac{608}{1806}D=1?0.337D=0.663$ 10. Now you calculate the Simpson's Diversity Index for Dive Site B: $D=$ 11. One index value on its own holds very little value, but once the researcher is able to compare it to another, it can begin to show us something. For example, in the above example, the higher value at Dive Site shows that from the data collected, Dive Site appears to be more diverse in species than Dive Site
