Figure 6. Group size effect for groups of individual networks.

Figure 6

The average across subjects of the weighted graph measures determined from the individual's network is shown as function of group size. A bootstrapping procedure was used (100 realizations) to randomly group the subjects with increasing group size. For graph measures the relative change (%) to the reference value (which is obtained by averaging across all subjects) are shown. Full lines denote the mean (bold) Inline graphic standard deviation of the metric. Dotted lines represent a relative change of Inline graphic 10%. Inline graphic: global efficiency; Inline graphic: the characteristic path length; Inline graphic: the mean betweenness centrality; Inline graphic: the mean local efficiency and Inline graphic: the mean clustering coefficient.
