4 important questions on Understanding Social Network Research - Major concepts in social network research - Network level concepts

What is does the density of a network measure?

The density is a measure of how many connections there are between actors compared to the maximum possible number of connections possible.

Centraliation of a network can also provide insights into network functioning. What does it refer to?

To the degree to which the network is centralized around one or a few actors.

Networks can also be characterized as to whether they have high or low reachability. What does it imply?

High-reachability networks are more efficient than low-reachability networks in the sense that messages can reach more of the people through the same number of intermediaries.

-> The average number of people reached per person over all possible steps.

The degree of structuring can be assessed in part by measures of balance. What does balance imply?

It incorporates the notions of reciprocity and transitivity. A network with a high degree of balance is one in which:

1. A tie between two people tends to be reciprocated

2. If two people have a common tie to a third person, then the two people tend to have a direct tie to each other (the three actors form a transitive triad)
