Using a biological formula to culculate “DIVERSITY INDEX”.
Statistics relate to human nature used to resemble the species.(e.g. nationality, industry types)

Simpson’s Diversity Index One of the most used index in Biological research It measures the probability that two individuals randomly
selected from a sample will belong to the same species.
METHOD
n = the total number of organisms of a particular speciesN = the total number of organisms of all species
