Fig 8. Mean values 〈Φ(N)〉, standard deviations σ(Φ(N)), max values max{Φ(N)}, and min values min{Φ(N)} for various fish group sizes.

Groups N = 2, N = 4, and N = 5 have three samples and group N = 3 has four samples. Parameters were set using the peak values of Fig 2. The mean values and standard deviations of integrated information Φ increase as the size of the fish school (N) increases.
