Figure 6. Group size effect for groups of individual networks.
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) standard deviation of the metric. Dotted lines represent a relative change of
10%.
: global efficiency;
: the characteristic path length;
: the mean betweenness centrality;
: the mean local efficiency and
: the mean clustering coefficient.
