What does closeness in a network measure?

• A. How quickly messages are relayed
• B. How independent or dependent individuals are in a group
• C. How many connections a person has
• D. How influential a person is

Answer: (B)

Closeness in a network measures how independent or dependent individuals are within the group. This concept is often used in social network analysis to determine how easily or directly one can reach others within the network. Closeness centrality, a common measure in this context, evaluates the shortest paths from a node (individual) to all other nodes in the network. A higher closeness value indicates that an individual has a more direct connection to others and, thus, is less dependent on the network structure to reach others. In contrast, options focusing on message relay speed, the quantity of connections, or individual influence pertain to different aspects of network analysis, such as network efficiency, degree centrality, or betweenness centrality, rather than simply measuring the interpersonal independence or dependence within the network structure.
