A typical form of OFD is a bimodal distribution, indicating the species in a community is either rare or common, known as Raunkiaer's law of distribution of frequencies.

Bimodal distributions are a commonly used example of how summary statistics such as the mean, median, and standard deviation can be deceptive when used on an arbitrary distribution.
33.
The bimodal distribution of sizes of weaver ant workers shown in Figure 2 arises due to existence of two distinct classes of workers, namely major workers and minor workers.
34.
Examples of variables with bimodal distributions include the time between eruptions of certain geysers, the circadian activity patterns of those crepuscular animals that are active both in morning and evening twilight.
35.
Routley & Husband ( 2003 ) examined the influence of inflorescence size on this siring advantage and found a bimodal distribution with increased siring success with both small and large display sizes.
36.
Platt's position was that hypertension was a simple disease caused by perhaps just one genetic defect, and he presented evidence of its autosomal dominant inheritance and a bimodal distribution of blood pressures, indicating that hypertensives were a distinct subpopulation in humans.
37.
If sufficiently separated, namely by twice the ( common ) standard deviation, so \ left | \ mu _ 1-\ mu _ 2 \ right | > 2 \ sigma, these form a bimodal distribution, otherwise it simply has a wide peak.
38.
Maye, Weiss, and Aslin found that infants who were exposed to a bimodal distribution of a non-native contrast that was initially difficult to discriminate were better able to discriminate the contrast than infants exposed to a unimodal distribution of the same contrast.
39.
The combined distribution of heights of men and women is sometimes used as an example of a bimodal distribution, but in fact the difference in mean heights of men and women is too small relative to their standard deviations to produce bimodality.
40.
But while the emphasis on producing blockbusters with a short theatrical life has created what Charles Cicchetti of Civic Economics, consulting group in Los Angeles, calls " a bimodal distribution of expensive and inexpensive films with few in the middle, " it is hard to identify an audience that isn't being served as well as it was in the past.
