Surveys
• The main advantage of surveys is that it is possible to survey a large number of
people in a timely and cost-effective manner.However, there is no way to
determine whether the sample taken is truly representative of the population.
• Variables are survey questions that measure some characteristic of the
population.Dependent variables change in response to the influence of
independent variables, while independent variables are those that when
manipulated will stimulate a change upon the dependent variables.
• In surveying, bias can refer to two situations: interviewer tendencies to hint at the
answer they would like to receive and thus influence the subjects' responses, or
the existence of a sample that shares some tendency that is not characteristic of

the entire population.
• There are several types of surveys: polls collect opinions, cross-sectional surveys
are given once to a group of people, and longitudinal surveys are the same
survey given multiple times to a group of people over a long period of time.
• To ensure the data reflect the characteristics of a population as accurately as
possible, sociologist use random sampling, representative sampling, and stratified
random sampling.Convenience samples are taken because of ease of access and
thus represent volunteer bias.

• There are several types of surveys: polls collect opinions, cross-sectional surveys are given once to a group of people, and
longitudinal surveys are the same survey given multiple times to a group of people over a long period of time.
• The various ways in which sociologists try to make their data reflect the characteristics of a population as accurately as
possible include random sampling, representative sampling, and stratified random sampling.Convenience samples are taken
because of ease of access and thus represent volunteer bias.
• Constructing a rigorous and effective survey requires a large sample size, a high response rate, and high generalizability
(confidence that the results from the sample apply to the general population).It also requires valid and reliable survey
questions.
• Valid survey questions are those that are accurate and measure what they claim to measure.
• A reliable survey question is one that is relatively free from bias errors.
• The different types of survey questions possible are open, allowing subjects to respond in their own words, or closed, providing
a set list of answers from which subjects must choose.The Likert Scale question is a common example of a closed survey
question.Demographic questions (which provide basic categorical information about subjects) can be open or closed.

Fieldwork/Observation
• Ethnographic work requires intensive and often immersive long-term participation
in the community that is the subject of research, typically involving physical
relocation (hence the term fieldwork).
• In participant observation, the researcher immerses himself in a cultural
environment, usually over an extended period of time, in order to gain a close and
intimate familiarity with a given group of individuals and their practices.
• Such research involves a range of well-defined, though variable methods:
interviews, direct observation, participation in the life of the group, collective
discussions, analyses of personal documents produced within the group, selfanalysis, and life-histories, among others.
Fieldwork and Observation
View on Boundless.com
• The advantage of ethnography as a technique is that it maximizes the
researcher's understanding of the social and cultural context in which human
behavior occurs.
• The advantage of ethnography as a technique is that it maximizes the
researcher's understanding of the social and cultural context in which human
behavior occurs.The ethnographer seeks out and develops relationships with
cultural insiders, or informants, who are willing to explain aspects of their
community from a native viewpoint.A particularly knowledgeable informant who
can connect the ethnographer with other such informants is known as a key
informant.

Experiments
• Experiments are controlled tests designed to prove or disprove a hypothesis.
• A hypothesis is a prediction or an idea that has not yet been tested.
• Researchers must attempt to identify everything that might influence the results of
an experiment, and do their best to neutralize the effects of everything except the
topic of study.
• Since social scientists do not seek to isolate variables in the same way that the
hard sciences do, sociologists create the equivalent of an experimental control via
statistical techniques that are applied after data is gathered.
• A control is when two identical experiments are conducted and the factor being
tested is varied in only one of these experiments.

Documents
• This kind of sociological research is generally considered a part of media studies.
• Unobtrusive research involves ways of studying human behavior without affecting
it in the process.
• Documents can either be primary sources, which are original materials that are
not created after the fact with the benefit of hindsight, or secondary sources that
cite, comment, or build upon primary sources.
• Typically, sociological research involving documents falls under the crossdisciplinary purview of media studies, which encompasses all research dealing
with television, books, magazines, pamphlets, or any other human-recorded

data.The specific media being studied are often referred to as texts.
View on Boundless.com
• Sociological research involving documents, or, more specifically, media studies, is
one of the less interactive research options available to sociologists.It can provide
a significant insight into the norms, values, and beliefs of people belonging to a
particular historical and cultural context.
• Content analysis is the study of recorded human communications.

Use of Existing Sources
• Archival research is the study of existing sources.Without archival research, any
research project is necessarily incomplete.
• The study of sources collected by someone other than the researcher is known as
archival research or secondary data research.
• The importance of archival or secondary data research is two-fold.By studying
texts related to their topics, researchers gain a strong foundation on which to base
their work.Secondly, this kind of study is necessary in the development of their
central research question.

Key terms
• Archival research An archive is a way of sorting and organizing older documents, whether it be digitally (photographs online, emails, etc.) or manually (putting it in folders, photo albums, etc.).Archiving is one part of the curating process which is typically
carried out by a curator.
• content analysis Content analysis or textual analysis is a methodology in the social sciences for studying the content of
communication.
• control A separate group or subject in an experiment against which the results are compared where the primary variable is low
or nonexistent.
• cross-sectional survey Cross-sectional studies (also known as cross-sectional analyses, transversal studies, prevalence study)
form a class of research methods that involve observation of all of a population, or a representative subset, at one specific point
in time.
• documentary research Documentary research involves the use of texts and documents as source materials.Source materials
include: government publications, newspapers, certificates, census publications, novels, film and video, paintings, personal
photographs, diaries and innumerable other written, visual, and pictorial sources in paper, electronic, or other "hard copy" form.
• ethnography The branch of anthropology that scientifically describes specific human cultures and societies.
• experiment A test under controlled conditions made to either demonstrate a known truth, examine the validity of a hypothesis,
or determine the efficacy of something previously untried.
• hypothesis Used loosely, a tentative conjecture explaining an observation, phenomenon, or scientific problem that can be
tested by further observation, investigation, or experimentation.
• longitudinal survey A longitudinal study is a correlational research study that involves repeated observations of the same
variables over long periods of time—often many decades.
• media studies Academic discipline that deals with the content, history, meaning, and effects of various media, and in particular
mass media.
• primary data Data that has been compiled for a specific purpose, and has not been collated or merged with others.
• qualitative Of descriptions or distinctions based on some quality rather than on some quantity.

Sociological Research
• sample A subset of a population selected for measurement, observation or questioning, to provide statistical information about
the population.
• secondary data Secondary data is data collected by someone other than the user.Common sources of secondary data for
social science include censuses, organizational records, and data collected through qualitative methodologies or qualitative
research.

Exhibits at a Science Fair
If you've ever competed in a science fair, you're already familiar with the way experiments are used in natural sciences.But because social life is so
complex, social scientists are rarely able to conduct such experiments.Instead, they use statistics to mimic experimental conditions with their data.

Abortions and Crime: Freakonomics Movie
Ethical guidelines and expenses often prohibit social scientists from conducting experiments, but creative researchers can take advantage of so-called
natural experiments to use a similar logic.Here, Freakanomics author Steven Levitt explains his most famous natural experiment, which found that
legalizing abortion led to a drop in crime.
