ison_fraternity.RdWeekly sociometric preference rankings among 17 men attending the University of Michigan in the autumn of 1956. 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, which makes this one of the earliest records of a social structure forming from scratch.
Each week, every man ranked all 16 others from most to least preferred. No ties in rank were allowed; each wave is a complete directed network. Two tie attributes record this:
rank: the raw ranking given, where 1 is the respondent's
first preference and 16 their last
weight: the ranking reversed (17 - rank), so that larger values
indicate stronger preference, as expected by weighted measures

#>The men are anonymised as A01 to A17.
Waves are numbered by the week of observation. Data were collected in
weeks 1 to 9 and 11 to 16; no data were collected in week 10.
The network therefore has 15 waves but a maximum wave number of 16.
