Fig. 5From: A novel metric to measure spatio-temporal proximity: a case study analyzing children’s social network in schoolyardsThe correlation of pairwise proximity for two playgroups: comparing the CCM of geodesic proximity (in green), temporal proximity (in red), and spatio-temporal proximity (in blue) among children in playgroup PG-1 and PG-2. On average, children in both groups have a higher correlation with peers from the same group and a lower correlation with peers from different groups. This difference is more significant in PG-1-A and less significant in senior playgroup, i.e., PG-2Back to article page
