Network density

from Wikipedia, the free encyclopedia

In the network density is a measure of social network analysis . Density is defined as the ratio of the existing relationships to the maximum number of possible relationships. It can have a value between 0% (= there are no relationships) and 100% (= there is the maximum possible number of relationships).

The network density can be defined mathematically - as seen above.

The density of a network can be calculated both for the entire network and for individual parts of a network. It has been assumed (since Elizabeth Bott ), among other things, that mutual social control is stronger in a denser network . The density is also an indicator of the activity in a network. Social control is strongest with (e.g. in a clique ) ( close-knit network ) and weakest ( loose-knit network , cluster ). "Partial strong links (tangles, clusters ) give up demarcation and analysis problems." (Clausen 2007, p. 456)
