Social Network Analysis (SNA) is a methodological approach used to study social structures through the use of network and graph theories. It focuses on mapping and measuring relationships and flows between people, organizations, or other social entities to understand their interactions, influences, and patterns within a network. SNA provides insights into how information, influence, or behaviors spread within social systems and is widely applied in sociology, marketing, epidemiology, organizational studies, and online social media analysis.
