WebbL' indice di Shannon-Wiener H' è un indice di diversità usato in statistica nel caso di popolazioni con un numero infinito di elementi. dove p j è la proporzione della j-esima specie (Σ j p j = 1) e s è il numero delle specie. Dividendo H' con il valore massimo possibile H' max =log e (s), si ottiene un indice compreso tra 0 e logaritmo di k. 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.
