Berger-Parker index. Measures the frequency of the most abundant species, D3(p) = max(p, 1 − p). (See the attached image of a graph to answer the below question, poll 1) Poll 1: Is D3 continuous A. yes B. no

Poll 1: Is D3 continuous
A. yes
B. no
The Berger-Parker index (Berger and Parker 1970) expresses the proportional importance of the most abundant type. This metric is highly biased by sample size and richness, moreover it does not make use of all the information available from sample. Dominance: D=nmaxN
where Nmax is the number of individuals in the most abundant species, and N is the total number of individuals in the sample.
OUTCOMES OF BERGER PARKER INDEX:-
More diverse communities have lower value of Dbp
