Step 1: Insert the total number in the set (89) into the formula N (N – 1) and solve: N (N – 1) = 89 (81 -1) = 7832 Put this number aside for a moment. Step 2: Calculate n (n – 1).
WebbThe Simpson’s Diversity Index is used to measure the level of biodiversity in a given area. It is concerned with the diversity of species present. The Simpson’s Diversity Index looks at two factors- richness and evenness. Species richness refers to the total number of species present in an ecosystem. Species evenness refers to the relative ...
