Sociological Research METHODOLOGY From Reading: Short Answer Write down the first three steps of the scientific method. Think of a broad topic that you are interested in and which would make a good sociological study—for example, ethnic diversity in a college, homecoming rituals, athletic scholarships, or teen driving. Now, take that topic through the first steps of the process. For each step, write a few sentences or a paragraph: 1) Ask a question about the topic. 2) Do some research and write down the titles of some articles or books you’d want to read about the topic. 3) Formulate a hypothesis. Quantitative vs. Qualitative Qualitative Attempt to collect information about the social world that cannot be converted to numeric form Collected in a number of ways: Participant observation Interviews Reviewing archives Quantitative Attempt to collect information about the social world that can be converted easily into numeric form Then uses statistical analysis to determine how changes in one factor affect another social outcome, while factoring out other simultaneous events Purpose of Qualitative and Quantitative Research To establish a causal relationship between social elements Qualitative Researchers Describes social processes in such detail as to rule out competing possibilities Quantitative Researchers By eliminating all other possibilities through their research design, hope to state with some certainty that one condition causes another Deductive vs. Inductive Deductive Approach: A research approach that starts with a theory, forms a hypothesis, makes empirical observations, and then analyzes the data to confirm, reject, or modify the original theory Deductive vs. Inductive Inductive Approach: A research approach that starts with empirical observations and then works to form a theory Journal: A sociologist observes the work-seeking habits of welfare recipients. After weeks of observation, trends emerge and the researcher forms a theory about the behaviors of this group. Is the sociologist in this example using a deductive or inductive approach? How would the sociologist study this phenomenon using the other approach? Causality vs. Correlation CORRELATION (association) DOES NOT EQUAL CAUSATION! Correlation is a simultaneous variation in two variables Correlation: Example A correlation exists between poor health and low income But to say two things are correlated is very different from stating that one causes the other For example: You might assert that bad health causes you to have a lower income and health– you get sick and can’t work, lose your job, etc. OR: Higher income leads to better health– can afford better doctors, access to fresh, healthful foods, gym in the office, etc. OR: A third reason that causes both? Possible Third Factor: Reckless Tendencies For example: you love spending your paycheck on designer clothes, fast cars and partying. This short-sighted behavior could negatively affect health. Could also affect income. Correlation Continued If we simply observe the two correlated phenomena– poorer health and lower income, they might not be at all affected except through a third factor (in this case, “reckless behavior”) In social science, it is MUCH easier to say there is a correlation between one factor and another than to say there is a causal relationship Causality Causality: the notion that a change in one factor results in a corresponding change in another Three factors needed: correlation, time order, and ruling out alternative explanations Determining Causality Example: Observation– notice variations in nutritional food across countries, also notice height differences which seem to correspond to differences in nutrition Now we need to establish a time order Have people in country A always been taller than people in country B? Or did changes in nutrition occur before increases (or decreases) in height? Rule out alternative explanations for the variations observed in both nutrition and height Third factor possibilities: groundwater supply– could lead to better nutrition through crop yields, but could also lead to cleaner drinking water and less infection (which is turns out to matter for height) In this case, the causal relationship between nutrition and height would be termed “spurious” or false, whereas the relationship between infection and height might be described as a “true” causal relationship The Problem of Reverse Causality Reverse Causality: a situation in which the researcher believes that A results in a change in B, but B, in fact, is causing A Does low income lead to poor health, or does poor health lead to low income? You might have heard… “Every time I eat chocolate, I get acne!” Third factor which causes both? - perhaps this person suffers from anxiety and stress. The stress causes him to eat chocolate, but at the same time causes acne to break out. This will lead to the two occurring very close in time, even though one isn't actually causing the other. Recent studies have proven that watching too much violence on television leads to people being violent in real life. Other variables? Example: both increasing violence on television and increasing violence in society might be caused by changing economic circumstances or something else entirely. Drinkers are more likely than non-drinkers to get lung cancer, suggesting drinking causes lung cancer. It turns out there is a strong correlation between consuming alcohol and developing lung cancer. The problem would be asserting that alcohol consumption causes lung cancer; the actual reason is that people who drink more also tend to smoke, or smoke more, than non drinkers. Many claim that marijuana is a “gateway drug” because those who have smoked marijuana are more likely than those who haven’t to go on to try other drugs. The problem would be asserting that marijuana use leads to increased use of other drugs; other variables? Those who are willing to try one drug are also willing to try other drugs: the cause – willingness to try or use drugs – must necessarily exist before one tries pot. Journal: Think, Pair, Share What is the difference between causality and correlation? Provide one example to illustrate the difference between the two. Variables Dependent Variables: The outcome the researcher is trying to explain Independent Variables: a measured factor that the researcher believes has a causal impact on the dependent variable Key independent variable: the most important one Change in your dependent variable DEPENDS on your independent variable Hypothesis Hypothesis: a proposed relationship between two variants, usually with a stated direction Direction of the relationship refers to whether your variables move together (positive) or in opposite directions (negative) Hypothesis Direction Example: We know that income is positively related to education: As people’s education increases, usually so too does their income Overt prejudice, on the other hand, is negatively related to education: as people’s education level increase, generally their levels of expressed prejudice decrease With a Partner: Create a 4 panel comic that describes and illustrates (colored neatly, with narration) one of the bullet points below Correlation/Causation Reverse Causality Variables (dependent, independent) Hypothesis/direction (positive, negative) Hypothesis Testing Operationalization: the process of assigning a precise method for measuring a term being examined for use in a particular study “Poverty Operationalization” One study focuses on poverty who fall below the official poverty One study focuses on the UN’s definition of poverty ($1 per day) Very different ideas of “poverty” to be studied Poverty Study Continued Once you decide how to define poverty, you must begin to consider all the variables related to the concept Education Employment Race Gender Poverty Study Continued Now, is poverty the dependent or independent variable? Interest: Want to examine the factors that cause poverty, and especially interested in the effect of parental education on children’s poverty levels Poverty Study Continued Now ready to pose the research question: “What effect do parents’ educational levels have on children’s chances of living in poverty as adults?” Hypothesis: The lower the educational level of parents, the greater the chance that their children will be poor as adults. Poverty Study Continued Other variables: race and family structure could be moderating variables Variables that affect the relationship between independent and dependent variables Poverty Study Continued Now we need to tell stories that explain why the hypothesis might be true Parents who are more educated have acquired more confidence and skills for succeeding in our economy and are more likely to pass on this knowledge and positive outlook to their kids at home Validity, Reliability, Generalizability Validity: the extent to which an instrument measures what it is intended to measure Reliability: likelihood of obtaining consistent results using the same measure Generalizability: the extent to which we can claim our findings inform us about a group larger than the one we studied Validity That the study measures what you intend it to If you step on a scale, and it measures your height, it’s not valid. If I ask you how happy you are with your life in general, and you tell me how happy you are with your school life in particular, it is not a valid measure of your life satisfaction Reliability How likely you are to obtain the same result using the same measure the next time A scale that’s off by ten pounds might not be totally valid– but it is reliable if every time I step on it, it reads exactly 10 pounds less than my true weight A clock that is five minutes fast is reliable, but not valid (not providing the actual time, which is what it is intended to measure) As for a measure in life satisfaction on a scale of 10, and you give a 10 out of 10 one week, and a 7 out of 10 the next, it might be a valid test, but not reliable. Generalizability Can we generalize our findings to a larger population? How do we determine if we can? Journal: Think, Pair, Share Give an example of a measure that is valid, but not reliable Then give an example of a measure that is reliable, but not valid. Journal: A sociologist analyzes the effects of social class and gender on intelligence based on standardized test scores. The test consistently gets similar results but actually measures the ability to read quickly. What are the independent and dependent variables in this example? Are the results of this study reliable, valid, both or neither? Creating and Testing Theory The most important thing to determine is what you want to learn and then contemplate the best possible way to collect the empirical data that would answer your question. Data Collection Participant Observation: A qualitative research method that seeks to observe social interactions in practice What this usually entails is “hanging out” and documenting people’s practices in a given society Some focuses more heavily on the participating, and some focuses more heavily on the observing– depending on the interests of the researcher and the appropriateness of participating The context in which the observations occur are called sites Usually several different sites are chosen, in order to compare findings Data Collection: Interview Interviews are another way to gather qualitative data Open-ended interviews: allow the subjects to go off on tangents Semi-structured or structured interviews– the researchers develop a specific set of questions to address with all respondents in a relatively fixed sequence Data Collection: Survey Research Survey: an ordered series of questions intended to elicit information from respondents A survey targets a specific population, people who are the focus of a study, such as college athletes, international students, or teenagers living with type 1 (juvenile-onset) diabetes. Most researchers choose to survey a small sector of the population, or a sample: that is, a manageable number of subjects who represent a larger population. The success of a study depends on how well a population is represented by the sample. In a random sample, every person in a population has the same chance of being chosen for the study. Quantitative and Qualitative Data in Surveys Quantitative Data: yes/no questions that would be easy to tabulate Qualitative Data: Complex questions with complex answers Ex) How do plan to use your college education? Harder to analyze and tabulate Research Design: Create a survey Follow the directions on the handout provided Field Research Field research refers to gathering primary data from a natural environment without doing a lab experiment or a survey. Researcher interacts with or observes a person or people, gathering data along the way. The key point in field research is that it takes place in the subject’s natural environment coffee shop or tribal village, a homeless shelter or the DMV, a hospital, airport, mall, or beach resort. Field Research Field research often begins in a specific setting The study’s purpose is to observe specific behaviors in that setting. Field work is optimal for observing how people behave. It is less useful, however, for understanding why they behave that way. You can't really narrow down cause and effect when there are so many variables floating around in a natural environment. Ethnography Ethnography is the extended observation of the social perspective and cultural values of an entire social setting. Ethnographies involve objective observation of an entire community. The heart of an ethnographic study focuses on how subjects view their own social standing and how they understand themselves in relation to a community. Case Study A case study is an in-depth analysis of a single event, situation, or individual. Uses: documents and archival records, conducts interviews, engages in direct observation, and even participant observation, if possible. Criticism: Difficult to general a case study, since it is designed for a single person or situation Experiment One way researchers test social theories is by conducting an experiment Investigate relationships to test a hypothesis. Scientific approach Two types Lab-based Natural/Field-based Experiment In a lab setting, the research can be controlled so that perhaps more data can be recorded in a certain amount of time. In a natural or field-based experiment, the generation of data cannot be controlled but the information might be considered more accurate since it was collected without interference or intervention by the researcher. As a research method, either type of sociological experiment is useful for testing if-then statements: if a particular thing happens, then another particular thing will result. Experiment The Hawthorne effect—people changing their behavior because they know they are being watched as part of a study. The Hawthorne effect is unavoidable in some research. In many cases, sociologists have to make the purpose of the study known. Subjects must be aware that they are being observed, and a certain amount of artificiality may result (Sonnenfeld 1985).
