Measures comparing cumulative distributions of fraction of aphids moving 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 distribution of INT comes closer to EXP than NON does. This is especially apparent in the and values. The three distributions are shown in Fig. 6(C).
