behaviors. In addition, researchers occasionally attempt to specify causes
when research results do not support such conclusions. If a research project
revealed that boating accidents increase as ice cream sales increase, for ex-
ample, we might be tempted to conclude that ice cream is a culprit in
boating accidents. Of course, nothing could be further from the truth. Both
ice cream sales and boating accidents simply increase as the weather warms
up, and they clearly are not related in terms of a cause-and-effect outcome.
Although this example is absurd, researchers need to beware of making
conclusions that are equally, if perhaps more subtly, absurd using research
data that do not support their conclusions.
Other weaknesses of survey research are specific to the data-collection
method researchers use in a project. Large personal interview surveys may
be costly, for example, requiring the training of field supervisors and in-
terviewers, as well as covering travel expenses and other costs associated
with interviews. Similarly, mail surveys typically take longer than other
survey research methods to complete because of the time associated with
mailing the questionnaires to a sample and receiving responses back from
participants. It is important to know the specific strengths and weaknesses
associated with each method of data collection, and these are discussed in
detail in chapter 10.
Other concerns associated with survey research apply in some way to
all survey data-collection methods. Sometimes respondents are inaccurate
in the answers they provide, for example, whether in a direct interview
or on a mailed questionnaire. Innacurate responses introduce error into
survey results. There are a variety of reasons for this problem. Sometimes,
respondents simply do not remember information about themselves or
their activities. They may simply make up a response rather than admit
they do not know an answer. This also is a problem when respondents lack
knowledge regarding the subject of a public affairs question, for example,
but answer the question anyway.
Respondents also may provide incorrect answers in an attempt to find
favor with interviewers, and some survey questions include responses that
are more socially desirable than alternative choices. In other instances,
participants may simply choose to deceive researchers by providing in-
correct answers to questions. Survey results concerning complex subjects
are further complicated by respondents who find it difficult to identify
and explain their true feelings, especially using simple numerical scales.
As a result, practitioners should consider the potential drawbacks to the
successful completion of a survey before they start a research project.
Despite the weaknesses of survey research, its benefits outweigh its
drawbacks for many research projects. Survey research is particularly use-
ful for description and association, a necessity given the often exploratory
and descriptive nature of many applied projects. In addition, a carefully
prepared questionnaire contributes to results that are reliable and accurate.
