Networks & Communities
Centrality within a network, group cohesion, and how community size relates to stability: a smaller, more specialized corner of sociology aimed at students studying network analysis specifically.
Calculators & Tools
Social Network Centrality Calculator
The Social Network Centrality Calculator computes degree, betweenness, and eigenvector centrality together from a typed list of connections between nodes. It ranks every node on all three measures, automatically flags bridge nodes where the most connected node differs from the most critical connector, and reports overall network density and average degree.
Group Cohesion Index Calculator
The Group Cohesion Index Calculator computes the sociometric cohesion index, dissociation index, and net cohesion score for a group from peer-nomination data. It automatically flags the sociometric star, the member receiving the most positive nominations, and any isolates who gave and received no nominations at all, then classifies the group cohesion level into a descriptive tier.
Community Size vs Stability Calculator
The Community Size vs Stability Calculator classifies a community size into one of Robin Dunbar's published group-size tiers and reports the natural contact interval for that layer. It also computes annualized growth rate and churn rate from optional prior-size and member-loss inputs, then combines size, growth, and churn into a set of plain-language stability risk flags.
