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.
