What Is Survey Research?
Survey research is a quantitative and qualitative
method with two important characteristics. First,
the variables of interest are measured using self-reports. In essence, survey
researchers ask their participants (who are often called respondents in
survey research) to report directly on their own thoughts, feelings, and
behaviours. Second, considerable
attention is paid to the issue of sampling. In particular, survey researchers
have a strong preference for large random samples because they provide the most
accurate estimates of what is true in the population.
Beyond these two characteristics, almost anything goes in survey
research. Surveys can be long or short. They can be conducted in person, by
telephone, through the mail, or over the Internet. They can be about voting
intentions, consumer preferences, social attitudes, health, or anything else
that it is possible to ask people about and receive meaningful answers.
Although survey data are often analyzed using statistics, there are many
questions that lend themselves to more qualitative analysis.
Most survey research is nonexperimental. It is
used to describe single variables (e.g., the percentage of voters who prefer
one presidential candidate or another, the prevalence of schizophrenia in the
general population) and also to assess statistical relationships between
variables (e.g., the relationship between income and health). But surveys can
also be experimental.
There are three main survey research
methods, divided based on the medium of conducting survey research:
- Online/ Email: Online survey research
is one of the most popular survey research methods today. The cost
involved in online survey research is extremely minimal, and the responses
gathered are highly accurate.
- Phone: Survey research
conducted over the telephone (CATI) can be useful in collecting data from
a more extensive section of the target population. There are chances that
the money invested in phone surveys will be higher than other mediums, and
the time required will be higher.
- Face-to-face: Researchers
conduct face-to-face in-depth interviews in situations where there is a
complicated problem to solve. The response rate for this method is the
highest, but it can be costly.
Further, based on the time taken, survey research
can be classified into two methods:
·
Longitudinal survey
research: Longitudinal
survey research involves conducting survey research over a continuum of time
and spread across years and decades. The data collected using this survey
research method from one time period to another is qualitative or quantitative.
Respondent behavior, preferences, attitudes are continuously observed over time
to analyze reasons for a change in behavior or preferences. For example,
suppose a researcher intends to learn about the eating habits of teenagers. In
that case, he/she will follow a sample of teenagers over a considerable period
to ensure that the collected information is reliable. Often, cross-sectional
survey research follows a longitudinal study.
·
Cross-sectional
survey research: Researchers
conduct a cross-sectional survey to collect insights from a target audience at
a particular time interval. This survey research method is implemented in
various sectors such as retail, education, healthcare, SME businesses, etc.
Cross-sectional survey research can either be descriptive or analytical. It is
quick and helps researchers collected information in a brief period.
Researchers rely on cross-sectional survey research method in situations where
descriptive analysis of a subject is required.
