Webband colors. As a class, we will be comparing the species diversity of the student and staff parking lots. The diversity index we will use is the Shannon Diversity Index. After determining the number of each species (car), in each parking lot, the Shannon Diversity Index will be calculated separately for the student lot and the staff lot. WebbThe Shannon index is given by the expression [math]H' = -\sum_ {i=1}^S p_i \, \ln p_i , \qquad (3) [/math] , where [math]p_i [/math] is the probability to find [math]n_i= N p_i [/math] individuals in the [math]i [/math] -th species ( [math]\sum_ {i=1}^S p_i = 1 [/math] ).

That's not the sum of -x ln x , it's the sum of -p ln p where each p is the proportion of x / sum(all x) .
