A diversity index is a quantitative measure that reflects how many different types there are in a dataset, and simultaneously takes into account how evenly the basic entities are distributed among those types. Given here is the Menhinick's Index Formula written as S / √(n), where S: the total number of identified groups and N: the total number of counted individuals.

Where,

M = Menhinicks Diversity Index

S = Number of Species Recorded

N = Total Number of Individuals in the Sample

Given above Menhinick's Index formula is derived based on the number of species recorded and the total number of individuals in the sample. Also, you can click on the above calculator link to find the result.
