Measures comparing cumulative distributions of angle to nearest neighbor φ in experiment (EXP), a social interaction model (INT) and a noninteracting control model (NON).

By measures of the difference between median values , the Kolmogorov-Smirnov distance , and the Kullback-Leibler divergence , the cumulative distributions for INT, NON, and EXP are nearly identical. Since φ is an angle measured in radians, the values of should be compared to the value 2π. The three distributions are shown in Fig. 6(B).
