Notes:
Ever see someone is a shopping mall with a clipboard who looks like they're
counting people? That's just what they are doing as they seek to randomize the
their sample. Shopping mall intercepts are among the best ways to gather
information on consumers for a couple of reasons: broad cross-sample of the
population, large number of people in malls on a daily basis, relatively
inexpensive, and consumers are generally not on a fixed schedule so they have
time to answer questions.
