Newcomb Fraternity (data)
The Newcomb Fraternity Data consits of 15 matrices recording weekly sociometric preference rankings from 17 men attending the University of Michigan in the fall of 1956. Each participant ranks all 16 others from best friend down to least friend.
The data are represented in 15 adjacency matrices of order 17x17 in files newfrat01.csv to newfrat15.csv. The entry in row i and colum j gives the rank of j in the ordered list of is friends (ordered from the best friend to the least). Row labels and column labels (actor names) are not included in the files, but the ordering is the same in all files.
