Title: September 21 Research Methods:
1September 21 Research Methods
- Begin discussion of social science research
methods - Steps in scientific method
- Key concepts in research design
- Forms of data collection
- Tie data to Thursdays discussion of theory
- Ask you to draft a question youd like to ask
your classmates (may do this on thurs).
2Is your name on this slide?
- Stacy Clelland, Mark Davis, Kristopher Goetz,
Ajiboye Laosebikan, - If so, please see us after class about your group
project.
3Summary from last time Qs???
- Nature remains the main source of material wealth
maintains the life-support functions of the
ecosphere - Rural areas comparatively rich in natural wealth
- What is natural capital and why is it important?
- Questions of natural capital
- Not all of nature is natural capital, based on
- Tech
- markets
- How are benefits distributed and who should
decide? - Are our models of natural capital sustainable?
- How do ALL of these questions speak to rural
places? - Natural resource and environmental sociology as
the study of the interaction between individuals,
social structure, and nature - Multiple theoretical perspectives can be used to
understand this interaction.
4Switching Gears Research Methods
- We are bombarded with statistics and figures how
do we separate the good stuff from the junk?
What criteria? - Polls a great example
- some show Bush with double digit lead, others
show Kerry with almost as much of a lead - Variation in support for Iraq war
- Being well grounded in soc sci research methods
helps you to ask good questions about the numbers.
5FundamentalTwo types of logic used in research
- Deductive start with known general principles,
then see if these hold in the real world (theory
testing) - Inductive start with observations of the real
world to develop general principles that explain
these observations (theory building) - In most research there is an interplay between
these approaches.
6An example the relationship between rural
residence and hunting participation
- Deductive start with the general logical
principles - Rural people live closer to places to hunt
(access) - Rural people more likely to have backgrounds
/employment that use resources (including
animals) - Rural people have different attitudes toward
nature - Ask Do these principles also result in rural
people being more likely to hunt? In what
circumstances? - Inductive start with observations of the real
world - rural residents are four times more likely to
participate in licensed, recreational hunting
than urban residents. - Ask what are some possible explanations for
this? How do we sort out between competing
explanations?
7The Scientific Method
- Define the problem
- Review the literature (general principles)
- Formulate a testable hypothesis
- Select (develop) an appropriate research design
- Collect and analyze the data
- Develop conclusions
New / changed (refined) research questions
8Defining the Problem What is involved?
- Identify a problem, issue or question you want to
examine - How would you decide on a research question?
- How does value neutrality come into play in
selecting a research question? - The Example Understanding rural and urban
participation in hunting
9Defining the problemYour theoretical approach
affects the kind of questions you ask
- Functionalist
- Examples?
- Conflict
- Examples?
- Symbolic interactionist
- Examples?
10Defining the problemYour theoretical approach
affects the kind of questions you ask
- Functionalist
- How are attitudes towards hunting passed down in
the family? - Conflict
- How are resources like access to land distributed
throughout society? - Symbolic interactionist
- What are the shared agreements about what hunting
means? - How are they created and communicated?
11Reviewing the literature Its more important
than the text indicates
- Provides the background for the entire study
- Which theoretical perspectives applied
- How concepts have been operationalized in other
studies - Results from prior researchused to formulate
hypotheses - Identify past research designshow have others
approached this type of question, avoid their
mistakes - What is already known? Has your question already
been answered? (dont re-invent the wheel)
12Important journals in rural sociology/ sociology
- Rural Sociology
- J. of Community Development Society
- American Journal of Sociology
- American Sociological Review
- Social Forces
- Plus specialty journals (according to topic) for
this - Environment and Behavior
- Society and Natural Resources
- Human Ecology Review
- Human Dimensions of Wildlife
13Reviewing the literature (cont.)
- Identify theoretical approaches to hunting
participation used in past (rural-urban) - Socialization / culture
- Opportunity / access
- Symbolic interaction /
- Use as the basis for operational definitions of
key concepts translate bigger concepts into
measurable variables (not as simple as you might
think!!!). How should we measure - Hunting participation (?)
- Rural / urban (?)
14Formulate a hypothesis
- What is a hypothesis?
- A testable statement about the relationship
between two or more measurable factors or
variables. - Key concepts in a hypothesis
- Independent variable (a variable that causes a
change in another variable) - Dependent variable (a variable that is caused by
the action of another variable) - Control variables (a variable held constant to
test the relative impact of an independent
variable. - The ability to assess cause (versus correlation)
15Example
Independent Variable
Dependent Variable
Rural Residence
Hunting Participation
16Example with control variable
Independent Variable
Dependent Variable
Rural Residence
Hunting Participation
Access to Land
17Another Example with a different control variable
Independent Variable
Dependent Variable
Rural Residence
Hunting Participation
Family member hunt
18Important characteristics of a testable
hypothesis
- Relatively simple
- Make sure the variables can be measured
- Indicate the expected direction of the
relationship (what causes what?) - Be clear about causation versus correlation
- causation An increase in X causes a decrease in
Y. - correlation A decrease in X is correlated with
(is associated with) a decrease in Y.
19More on Causation vs. Correlation
- Many correlations are meaningless from a causal
standpoint!! - Pos association between height and interest in
PSU football. - Pos association between incidence of forest fire
and average age of local residents. - (whats wrong with these)
- Sociologists seek to identify causal links
between variablesthis is ideal, BUT difficult
when dealing with humans - studying the same people over time (time order is
one way to establish causality) - Random assignment to treatment / control groups
- Most often, sociologists have correlations but
use theory to help identify cause
20An example Correlation versus causation
- Relationship between mortality and income
- Correlation Poor people are more likely than
wealthy people to die at younger ages - So hypothesize High income decreases mortality
risks - (lots of theory to support this hypothesis)
21An example Correlation versus causation (cont.)
- But, also argued that poor health or disability
cause both earlier death and lower incomes. - This is an alternative hypothesis.
- How do we test these (conflicting) hypothesis?
By the way we decide to collect and analyze the
datathe research design.
22Research Designs Collecting and analyzing the
data
- Primary Data Collection (you do it yourself)
- Experiments
- Surveys
- Qualitative techniques observation, interviews
- Secondary data analysis (you use data someone
else already has collected) - Quantitative i.e., survey data
- Qualitative techniques review of secondary
materials -
23Experimentstest hypotheses
- Ideal way to determine causal relationshipsbased
in natural sciences model - Use experimental and control groupspeople
randomly assigned to groups - A treatment is applied to the experimental group,
but not the control group - Both groups are examined and the outcome or
dependent variable is measured for both - The values of the dependent variable are compared
across the experimental and control groups to
test if they are different.
24Experiments (cont.)
- Difficult to conduct experiments in social
research - Often not feasible cant do the manipulation
- Ethical issues potential risks to humans from
receiving the treatment, or consequences if they
dont receive the treatment (e.g., testing new
drugs school-based interventions)
25Surveystest hypotheses
- Used when experimental design is not feasible
- Allows large sample sizes
- Collect information to test multiple hypotheses
at one time - By sampling carefully and asking the right
questions, differences across groups can be
determined
26Survey questions
- A series of questions respondents answer
- How satisfied are you with the quality of
education you are getting at PSU? (1very
dissatisfied, 5very satisfied) - What was your high school GPA?
- A series of statements respondents agree or
disagree with - The profs at PSU assign too much reading
(1agree, 5disagree) - An open-ended question where respondents write a
short answer - What single PSU course have you found the most
worthwhile? - Or a longer answer
- How did you decide what to choose for your Major
at PSU?
27Survey methods
- Mail
- Phone
- Face to face
- Each has advantages and disadvantages
28Potential problems with surveys
- Declining response rates
- Confusion with marketing surveys
- Respondent willingness to answer complex or
personal questions truthfully - Relationship between actual behavior and what
people say they do - Recall problems
- Social desirability bias
29Qualitative Research
- Often used to generate hypotheses rather than
test them (good when relatively little prior
knowledge exists) - Can go much deeper
- Some phenomena not easily reduced to 5 point
scales - Ethnography often through participant observation
- Case studies
- Participatory rapid appraisal
30Qualitative Research
- Often used to generate hypotheses rather than

- Some phenomena not easily reduced to 5 point
scales - Ethnography often through participant observation
- Case studies
- Participatory rapid appraisal
31Potential issues with qualitative methods
- Generally, limited to specific locations,
situations (harder to create general principles) - Hard to replicate the study (time, researcher,
research subjects vary) - Presence of researcher changes what youre
studying (Hawthorne effect) - Lack of precise definitive answers not as
scientificmore difficult to observe the
working of the scientific method. - Potentially harder to defend / justify results
32Secondary data analysis
- Use existing data sources
- Surveys or interviews others have designed and
administered (Censuses, Add Health, YBSS) - Administrative data (from government) (Uniform
Crime Reports, Vital Statistics, welfare data,
school data) - Other existing sources (newspapers, voting
records, scientific records, books, transcripts,
movies, commercials)
33Potential issues with secondary data
- Validity issues do these data really get at your
hypotheses? (cant ask things exactly the way you
want them). - Dont always know all the particulars about how
the data was collected. - May not apply to your specific population of
interest.
34Issues in Data Collection and Analysis
- Who do you want to find out aboutsample
selection - Entire populationcensus
- Random sample
- Stratified samplesubpopulation of special
interest - When is a sample representativeor representative
of whom?
35Reliability and validity
- Important for measurement of all variables
- Reliabilitythe extent to which a measure
provides consistent results - Validity the extent to which a measure truly
reflects the phenomenon or concept under study
36An illustrationof reliability and validity
Valid, not Reliable
Reliable, not Valid
Valid and Reliable
37Class example hunting participation by urban /
rural residence
- What is the best way (research design) to test
our hypothesis? - How will we obtain our data?
- What is the population to which we want to make
inference? - If we do the study in PA, how much confidence do
we have that similar result would occur in other
places? - Should we sample, if so how will we do that?
38Class example hunting participation by urban /
rural residence
- Important variables to measure
- Operational definitions
- Dependent variable(s)
- Independent variable(s)
- Control variable(s)?
- Will we be able to determine causation or are we
limited to correlation?
39Survey question of your classmates
- Not open ended (have categories)
- Content
- Attitudinal
- Experiential
- Try to be as (a) specific, (b) unbiased as
possible e.g., attitudes toward logging - Are you a tree hugger who thinks rural families
are unimportant? - Do you care about the rural environment?
- I would support a policy that protected Old
Growth forests even if it meant losing some rural
logging and timber processing jobs.
40Next class
- Continue examining scientific method and research
design - Talk about the ethics of social research
- Begin preparation of an in-class survey, so think
about questions related to topics in this course,
and control variables
