The current study employed a survey

The current study employed a survey research method that is widely used
for information technology and communication research. In surveying the
community network users, the current study chose a single community
network. A multisite study would need to deal with the influence of many
known and unknown extraneous variables, such as differences in computer
and networking resources, staff expertise, organizational structures, service
priorities, size and urbanization of the service area, and so forth [3]. Unless
these extraneous variables were properly controlled for, their influence
would contaminate the relationships between research variables. A single
study site helped avoid this problem and made interpretations of the research
findings more unequivocal.
