SOLVED: Calculating the Simpson's Index of Diversity (DS) = 1 - Σ(Pi^2)This means to take the sum or add everything up. Pi represents the proportion of a specific species in a sampling area. Pi = (# of individuals of one species) / (total # of individuals of all species).Species 1Species 2Species 3Species 4Species 5# of individuals10 (red ants)2 (black beetles)2 (pill bugs)1 (earthworm)5 (grasshoppers)Pi10/20 = 0.52/20 = 0.12/20 = 0.11/20 = 0.055/20 = 0.25Pi^2(0.5)^2 = 0.25(0.1)^2 = 0.01(0.1)^2
