Data and Measures

The data collected by Bernard and Killworth (1977) and Bernard et al. (1979) comprise two networks (behavioral and recall) of the communication frequency of four different groups of individuals. Table 21.1 provides a basic description of these networks. The Ham, Off, and Tech data sets were collected by Bernard and Killworth (1977), and the Frat data set was collected by Bernard et al. (1979). The original data files (i.e., before transformation) for these networks are part of the public data sets included in UCINET (Borgatti, Everett, & Freeman, 2006).

Description of Networks

Table 21.1 provides an overview of the four data sets. For each data set, the behavioral network captures the frequency of dyadic interactions, and the recall network presents actors’ recall of these interactions. The recall information for the Off and Tech networks was obtained using a ranking procedure: each actor was given a deck of cards containing the names of

the other employees and was asked to rank the cards according to “how often they talked to others in the office during a normal working day” (Bernard et al., 1979, 194). For the Frat and Ham networks, each actor was asked to give a rating of his or her interactions with the other participants on a scale from 1 to 5 for the Frat network and 1 to 9 for the Ham network.
