It characterizes networked structures in terms of nodes (individual actors, people, or things within the network ) and the ties, edges, or links (relationships or interactions) that connect them. SNA measures and maps the flow of relationships and relationship changes between knowledge-possessing entities. While these relations may be formed by particular individuals, social network analysis is not limited to microlevel interactions.

The course will review foundational concepts and applications of social network analysis in learning analytics. You will also learn how to use igraph and statnet R packages to manipulate, analyze , and visualize network data. The nodes in the network are the people and groups while the links show relationships or flows between the nodes. Through quantitative metrics and robust visual displays, police can use SNA to discover, analyze , and visualize the social networks of criminal suspects.
