These are the values of the directed clustering coefficient (c±) for all networks to which the statistic applies and for which it was computed. In total, it has been computed for 317 networks.
The directed clustering coefficient (c±) equals the proportion of directed 2-paths that are completed by a third edge oriented in the same direction as the 2-path.
The full definition of the directed clustering coefficient as well as its properties and relationships to other graph statistics can be found in the KONECT handbook.
