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

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).
