Newcomb's Fraternity Networks

Description

These 14 networks record weekly sociometric preference rankings from 17 men attending the University of Michigan in the fall of 1956; Data were collected longitudinally over 15 weeks, although data from week 9 are missing.

Format

A list of 15 networks.

Details

The men were recruited to live in off-campus (fraternity) housing, rented for them as part of the Michigan Group Study Project supervised by Theodore Newcomb from 1953 to 1956. All were incoming transfer students with no prior acquaintance of one another.

The data set, derived from one in the unreleased netdata package, contains a network list newcomb with 14 networks. Each network is complete and contains two edge attributes:

list("rank")

the preference of the ith man for the jth man from 1 through 16, with 1 being the highest preference.

list("descrank")

the same, but 1 indicates lowest preference.
