SAMPLING METHODS FOR
INTERNET-BASED SURVEYS
This section describes specific types of
Internet-based survey and the sampling methods
that are applicable to each. We concentrate
on differentiating whether particular sampling
methods and their associated surveys allow for
generalization of survey results to populations
of inference or not, providing examples of
some surveys that were done appropriately
and well, and others that were less so.
Examples that fall into the latter category
should not be taken as a condemnation of
a particular survey or sampling method,
but rather as illustrations of inappropriate
application, execution, analysis, etc. Couper
(2000: 465–466) perhaps said it best,
Any critique of a particular Web survey approach
must be done in the context of its intended purpose
and the claims it makes. Glorifying or condemning
an entire approach to survey data collection should
not be done on the basis of a single implementation,
nor should all Web surveys be treated as equal.
Furthermore, as we previously discussed,
simply because a particular method does not
allow for generalizing beyond the sample does
not imply that the methods and resulting data
are not useful in other research contexts.
Similarly to Couper (2000), Table 11.2
lists the most common probability and nonprobability
sampling methods, and indicates
which Internet-based survey mode or modesmay be used with each method. For example,
it is possible to conduct both web and e-mail
surveys using a list-based sampling frame
methodology. Conversely, while it is feasible
to conduct an entertainment poll by e-mail,
virtually all such polls are conducted via web
surveys.
