Table 2. Measures comparing cumulative distributions of angle to nearest neighbor φ in experiment (EXP), a social interaction model (INT) and a noninteracting control model (NON).

Comparison
EXP vs. INT	0.0431	0.0085	0.0152
EXP vs. NON	0.0352	0.0128	0.0135
INT vs. NON	0.0078	0.0057	0.0035

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).
