# Simpson Diversity Index Calculator

Here is the Simpson Diversity Index Calculator to find the Simpson Index by finding the mean deviation for the given grouped data. The Simpson diversity index is a quantitative measure that reflects how many different types are there in a dataset, and how evenly the basic entities are distributed among those types in the data set. The Simpson Diversity Index ranges from 0 to 1. Greater the value, greater the sample diversity. Enter the data in this Simpson index calculator and click calculate.

#### Formula:

Simpson's Diversity Index = 1-D
E_{1/D} = (1 / D) / S
**Where,**
D = Simpson's Index of Diversity
S = Sum of numbers data
