SNA, or Social Network Analysis, is a method of studying and understanding the relationships and interactions between individuals or groups within a social system. It involves analyzing the patterns of connections, communication, and influence within a network to gain insights into the structure and dynamics of social relationships. SNA is used in various fields, including sociology, psychology, and marketing, to uncover hidden connections and identify key players within a network. By mapping out the complex web of relationships, SNA helps us better understand the social fabric that shapes our lives and behaviors.
