Sociological Research Methods: Surveys and Field Research
Surveys
- Social researchers design studies by selecting from widely used data-collection methods or by analyzing existing sources; planning the research design is a key step in any sociological study.
- Primary source data collection methods include:
- survey
- participant observation
- ethnography
- case study
- unobtrusive observations
- experiment
- Secondary data analysis uses existing sources.
- Every research method has plusses and minuses; topic of study influences method choice.
- Researchers should think of themselves as architects and their research design as a blueprint.
- Entry into social environments involves ethical considerations: anonymity vs overt presence; some situations require informing participants, others require keeping participants unaware; some contexts (e.g., prisons, Klan meetings, early education) make unobtrusive observation impractical or unsafe.
- Researchers choose methods that best fit the topic, protect participants, and align with their overall research approach.
- Field realities may limit invisibility of the researcher; some settings require overt presence or other methods.
Surveys
- Definition: A survey collects data from subjects who respond to a series of questions about behaviors and opinions, often via a questionnaire or interview.
- It is one of the most widely used scientific research methods.
- Large-scale example: The 2020 U.S. Census is a large-scale survey intended to gather sociological data.
- Historical context: Since 1790, the U.S. government has conducted a survey with six questions to collect demographic data; currently, the Census is conducted in the United States and five territories and consists of 12 questions.
- Not all surveys are sociological research; many surveys focus on marketing needs or strategies rather than testing a hypothesis or contributing to social science knowledge. Examples of non-sociological questions include:
- "How many hot dogs do you eat in a month?"
- "Were the staff helpful?"
- Not all polls are generalizable: e.g., Nielsen Ratings measure popularity of TV programming, but polls by specific TV programs (e.g., American Idol) are administered to an unrepresentative population (the show’s audience) and cannot be generalized.
- Sociologists conduct surveys under controlled conditions for specific purposes.
- Surveys gather different types of information and can track:
- preferences for presidential candidates
- reported behaviors (e.g., sleeping, driving, texting)
- demographic variables (e.g., employment status, income, education levels)
- Target population vs. sample:
- Population: the focus of the study (e.g., college athletes, international students, teenagers living with type 1 diabetes).
- Sample: a manageable number of subjects chosen to represent the larger population.
- Representativeness of the sample determines study success.
- Random sampling: Every person in the population has the same chance of being chosen.
- Probability of selection in a simple random sample:
p = rac{n}{N}
where
- n = sample size,
- N = population size.
- Process after selecting subjects:
- Researchers inform subjects of the nature and purpose of the survey up front.
- If they agree to participate, researchers thank them and may offer access to the study results.
- Researchers provide an instrument to gather information; a common instrument is a questionnaire.
- Question formats:
- Closed-ended questions (yes-no, multiple-choice) yield quantitative data.
- Open-ended questions require short essay responses and yield qualitative data.
- Data collected:
- Quantitative data: data in numerical form that can be counted and statistically analyzed. Examples include tallying how many “yes” vs “no” responses and converting to percentages.
- Qualitative data: data expressed as words and descriptions; more subjective and harder to organize, but rich in-depth material.
- Mixed data outcomes: Surveys can yield both quantitative and qualitative data (e.g., demographics plus reasons for educational choices).
- Interview as a survey method: A one-on-one conversation allowing clarification, deeper exploration, and flexibility beyond predetermined response options; aims to avoid steering or prompting responses and to build trust.
- Anonymity and honesty: Anonymous responses can increase honesty for sensitive topics (e.g., personal beliefs, political views).
- Data collection modes: The survey can be carried out online, over the phone, by mail, or face-to-face.
- Field research context: When data are collected outside a laboratory, library, or workplace, researchers are conducting field research, which is covered in the next section.
Field Research (Natural Environment)
- Field research involves gathering primary data from a natural environment, requiring researchers to enter new settings and observe, participate, or experience those worlds.
- In field work, researchers are the ones operating outside their usual environment; they interact with or observe people in their natural settings.
- Examples of settings: coffee shops, tribal villages, homeless shelters, the DMV, hospitals, airports, malls, beaches, resorts.
- Purpose: To observe specific behaviors within a setting and to understand why people behave that way in real environments.
- Limitations: It can be difficult to isolate cause and effect in natural settings because many variables are present simultaneously.
- Relationship to data interpretation:
- Field research often identifies correlations rather than causal relationships, due to the complexity of natural environments.
- The data gathered in sociology frequently indicate correlations rather than definitive causation.
- Key takeaway: Field research emphasizes context and behavior in real-life environments, trade-offs include less control and reduced ability to make causal inferences.
Ethical and Methodological Considerations (implied throughout)
- Protecting participants and ensuring their safety and privacy.
- Choosing the method that best fits the topic while maintaining ethical standards.
- Balancing anonymity with the need for informed consent and transparency when appropriate.
- Avoiding deception or prompting that could bias results or undermine reliability.
Connections and Real-World Relevance
- Surveys are foundational for understanding how people think, feel, and act, and for tracking trends over time.
- Survey design (question type, sample representativeness, mode of administration) critically affects the validity and generalizability of findings.
- Field research complements surveys by capturing behaviors and contexts that surveys may not reveal, though it introduces challenges in establishing causality.
- Real-world data sources (e.g., census data, Nielsen ratings) illustrate how measurement choices influence what conclusions can be drawn and how results generalize to broader populations.
- Throughout, the emphasis is on researchers designing a blueprint (the research design) that aligns data collection methods with the study’s aims, ethical constraints, and the realities of the setting.
Key Terms (glossary)
- Population: the entire group about which the researcher wants to draw conclusions.
- Sample: a manageable subset of the population used to represent the population.
- Random sample: a sample in which every member of the population has an equal chance of being selected.
- Instrument: a tool used to gather information (commonly a questionnaire).
- Questionnaire: a form containing questions for respondents to answer.
- Closed-ended questions: questions with predetermined response options (e.g., yes/no, multiple choice).
- Open-ended questions: questions allowing free-text responses.
- Quantitative data: numerical data that can be counted and statistically analyzed.
- Qualitative data: descriptive data expressed in words, narratives, or observations.
- Field research: research conducted outside the laboratory in the subject’s natural environment, emphasizing observation and participation.
- Correlation vs. causation: correlation indicates a relationship between variables; causation implies that one variable causes changes in another.
- Informed consent: ethical obligation to inform participants about the study and obtain their voluntary agreement to participate.
- Anonymity: ensuring participants’ identities remain unknown to researchers and others.
- Leading questions: questions that steer respondents toward a particular answer; should be avoided to maintain reliability.
