Network Analysis is a method used to study and understand the relationships and interactions within a network. This can include social networks, computer networks, or biological systems. By examining how different nodes (or entities) connect and communicate, researchers can identify patterns, trends, and key influencers within the network. In social network analysis, for example, researchers might look at how individuals are connected through friendships or professional relationships. This helps in understanding how information spreads, how communities form, and how certain individuals can impact group behavior. Overall, network analysis provides valuable insights into complex systems.
