Sociometry is a quantitative method used to measure social relationships and dynamics within a group. It involves mapping out connections between individuals based on their preferences, interactions, and emotional ties. This technique helps identify patterns of behavior, social structures, and the overall cohesion of a group. Developed by Jacob Moreno in the early 20th century, sociometry employs various tools, such as sociograms, to visually represent these relationships. By analyzing the data, researchers can gain insights into group dynamics, identify leaders, and understand how social networks influence individual behavior and group outcomes.
