Moreno Highschool Friendship Network

AnalyzedSmallgraphEducationSocial graph

A Small highschool in Illinois (offline survey, 1957–1958) dataset of 70 nodes and 366 edges, collected by J.L. Moreno via sociometric survey. Each record contains directed edges: True, weighted: True, signed: False. This directed network contains friendships between boys in a small highschool in Illinois. Each boy was asked once in the fall of 1957 and the spring of 1958. This dataset aggregates the results from both dates. A node represents a boy and an edge between two boys shows that the left boy chose the r. Suitable for community detection, friendship network analysis, social influence.
