WebbSimpsonās Index (D) measures the probability that two individuals randomly selected from a sample will belong to the same species. This is the version of the equation in the QCAA ā¦ WebbFigure 1 ā Simpsonās Diversity Index Figure 1 shows the D and 1/D indices. Cell B7 contains the formula =SUMSQ (B5:F5) and cell E7 contains the formula =SUMPRODUCT (B4:F4,B4:F4-1)/ (G4* (G4-1)). Note that for a large population, the maximum value of D is 1/k, and so the maximum value of 1/D is k.
