SOCIOLOGICAL RESEARCH METHODS
RESEARCH METHODS
 Research Methods
 Approaches to inquiry
 Used to describe, explore, and explain social reality
 Quantitative Methods
 Used to collect numerical information or information that
can be converted into numerical data
 Qualitative Methods
 Used to collect information that is not readily convertible
into numerical data

THEORIES AND HYPOTHESES
 Theory
 Statement explaining the relationship between
phenomena of interest
 Hypothesis
 Testable expectation about the relationship between
phenomena of interest
CONCEPTS AND VARIABLES
 Concepts
 Imprecise mental abstractions of phenomena
 Concepts are the building block of theories (Babbie
2013)
 Variables
 Concepts comprised of at least two measurable
categories
EXAMPLES OF COMMON VARIABLES IN
SOCIOLOGICAL RESEARCH
 Demographic Characteristics
 Race/ethnicity
 Gender
 Socioeconomic Status
 Income/Assets
 Education
 Other Variables
 Perceived Discrimination
 Social Isolation
RESEARCH PROCESS: STAGE 2-PLANNING
Research Method
Specify
Concepts/Variables
Operationalization
Population/Sample
COMMON RESEARCH TOOLS
 Surveys
 Face-to-Face
 Mail
 Telephone
 Internet
 Qualitative Field Research
 In-Depth Interviews
 Ethnography
 Participant Observation
ADDITIONAL RESEARCH TOOLS
 Content Analysis
 Experiments
 Historical Research
 Evaluation Research
OPERATIONALIZATION
 Operationalization
 Operationalization is the process where we specify how we
will measure concepts of interest unambiguously
 Example of operationalization
 We will measure education with four mutually exclusive
categories
 LESS THAN HIGH SCHOOL
 HIGH SCHOOL GRADUATE / GED
 SOME COLLEGE
 COLLEGE GRADUATE OR HIGHER
RESEARCH PROCESS: STAGE 3-DATA
COLLECTION, ANALYSIS, AND DISSEMINATION
Data
Collection
Data
Processing
Analysis Reporting
GATHERING DATA
 Establish Population of Interest
 Primary vs. Secondary Data
 Sampling technique (primary data collection)
POPULATIONS AND SAMPLES
 Population
 Entire collection of units of interest
 E.g., All adults in the United States
 Sample
 A subset of units from our population of interest
 E.g., 2,000 adults in the United States
SAMPLING TECHNIQUES:
NONRANDOM SAMPLING
 Nonrandom Sampling
 Can be used naively to get an easy sample
 Used more appropriately in qualitative research
 Provides one with good informants
 More attention on detailed data than generalizable data
SAMPLING TECHNIQUES:
RANDOM SAMPLING
 Random Sampling
 Random means that samples are selected according to
chance, not personal judgment
 Generally used in quantitative research
 Intended to provide a representative sample
QUALITATIVE DATA PROCESSING/ ANALYSES
 Transcription
 Coding and Memoing
 Finding Patterns in the Data
 Summarizing
STATISTICAL ANALYSES
 Statistic
 Numerical summary of a sample
 Parameter
 Numerical summary of a population
STATISTICAL ANALYSES (CONT.)
 Descriptive Statistical Analyses
 Analyses used to describe your sample
 E.g., what is the average income in your sample of
2,000 adults in the United States?
 Inferential Statistical Analyses
 Analyses that uses information from the sample to make
estimates about the population of interest
 E.g., based on the sample data, what is the estimated
average income of all adults in the United States?
STATISTICAL ANALYSES (CONT.)
 Univariate Statistics
 Percentage and Rates
 Averages
 Multivariate Statistics
 Correlation
 Regression Models
RELIABILITY AND VALIDITY
 Reliability-Degree to which an instrument or test
yields similar results on repeated trials
 Reliability pertains to the consistency of results
 Tells us that we are measuring something—not
necessarily what we want though
 Validity-Degree to which an instrument or test
actually measures what we intend to measure
RELIABLE, BUT NOT VALID
RELIABLE AND VALID
NOT RELIABLE, NOT VALID
HYPOTHESIS TESTING
 Null Hypothesis-default position; assumed to be
true until proven otherwise
 Null hypothesis typically specifies that there is no
relationship between 2 or more phenomena
 Alternative Hypothesis-The hypothesis for which
we are trying to find support
 Hypotheses are falsifiable, but never proven
3 CRITERIA FOR CAUSALITY
 Correlation
 2 variables must be related in some way
 Time-Order
 The causal mechanism must precede the effect in time
 Non-Spuriousness
 Relationship between 2 variables cannot be explained
by some third variable
RESEARCH ETHICS
 Institutional Review Board (IRB) approval
 Informed Consent
 Debriefing after experiments
 DO NO HARM TO PARTICIPANTS/SUBJECTS!
