Lastly, she can use the following formula to calculate the Shannon Diversity Index: H = -Σpi * ln(pi) For this example, she can take the sum of the last column and multiply by negative one: The Shannon Diversity Index for this community is 1.49. She can also use the following formula to calculate the Shannon … Visa mer Suppose a biologist wants to measure the diversity of species in a local forest. She collects the following data: Visa mer Next, the biologist can calculate the proportion of the community made up of each species. For example, there are a total of 105 individuals and 40 are classified as species A. Thus, species A makes up 40 /105 = … Visa mer Feel free to use this Shannon Diversity Index Calculatorto automatically calculate the Shannon Diversity Index for any dataset. Visa mer The Shannon index has been a popular diversity index in the ecological literature, where it is also known as Shannon's diversity index, Shannon–Wiener index, and (erroneously) Shannon–Weaver index. The measure was originally proposed by Claude Shannon in 1948 to quantify the entropy (hence Shannon entropy, related to Shannon information content) in strings of text.
