Social network theory is a branch of sociology that analyzes the relationships between individuals and groups within a society. It explores how these connections affect various aspects of social life, including behavior, communication, and the spread of information.

The Basics of Social Network Theory

Social network theory views individuals as nodes or points in a network, with connections or ties representing relationships between them. These ties can be based on different factors such as friendship, kinship, work, or shared interests. The analysis of these networks focuses on understanding how the structure and characteristics of these ties influence individual behavior and collective outcomes.

1. Nodes: Nodes represent individual actors or entities within a social network. They can be people, organizations, or even countries.

2. Ties: Ties are the connections between nodes.

They can be strong (e.g., close friends) or weak (e., acquaintances).

3. Strength of Ties: The strength of a tie refers to the emotional intensity, time investment, and reciprocity within a relationship.

4. Density: Density measures how interconnected nodes are within a network. It quantifies the extent to which individuals in a network know each other.
