1. A California social research analyst is asked to determine whether
participation in a county employment program reduces the duration
of unemployment. Participants are not randomly assigned;
individuals voluntarily enroll. Which research design provides the
strongest basis for estimating a causal effect under these
circumstances?
A. Cross-sectional descriptive study
B. Randomized controlled trial
C. Observational study with statistical adjustment for measured
confounders
D. Simple before-and-after comparison without controls
Answer: C. Observational study with statistical adjustment for
measured confounders
Rationale: In a voluntary enrollment setting, random assignment is
unavailable. An observational design can estimate associations and
potentially improve causal inference by controlling for measured
confounding variables such as age, education, prior employment
history, and baseline unemployment duration. However, statistical
adjustment cannot automatically eliminate bias from unmeasured
confounding. A simple before-and-after comparison is particularly
vulnerable to history, maturation, and selection effects.

,2. A researcher wants to measure residents' perceptions of
neighborhood safety. Which operationalization is most appropriate?
A. Define neighborhood safety solely as the number of police officers
assigned to the area
B. Define neighborhood safety as a measurable construct using
indicators such as perceived safety, reported victimization, and relevant
environmental conditions
C. Ask researchers whether the neighborhood seems safe
D. Use property values as the only measure of safety
Answer: B. Define neighborhood safety as a measurable construct
using indicators such as perceived safety, reported victimization,
and relevant environmental conditions
Rationale: Operationalization converts an abstract construct into
measurable variables. "Neighborhood safety" is multidimensional and
may include subjective perceptions and objective indicators. Using
multiple theoretically relevant indicators generally provides a more
defensible measurement strategy than relying on a single proxy.
3. A survey contains a question asking, "Don't you agree that the
county should continue its highly successful youth program?" What
is the principal methodological problem?
A. Sampling error
B. Leading wording
C. Randomization failure
D. Ecological fallacy
Answer: B. Leading wording
Rationale: The question contains persuasive language—"highly
successful"—that presupposes a favorable evaluation and may
2
,influence respondents. Neutral wording would reduce response bias,
such as asking, "To what extent do you support or oppose continuing
the youth program?"
4. A population contains 60% urban residents and 40% rural
residents. A researcher wants the sample to preserve this
composition. Which sampling method is most appropriate?
A. Convenience sampling
B. Stratified random sampling
C. Snowball sampling
D. Purposive sampling
Answer: B. Stratified random sampling
Rationale: Stratified random sampling divides the population into
relevant strata and samples from each according to a predetermined
allocation. Proportionate stratification would produce approximately
60% urban and 40% rural respondents, improving representation of
both groups.
5. A survey obtains 800 responses from 2,000 randomly selected
residents. Which term describes the proportion of selected
individuals who actually responded?
A. Sampling fraction
B. Response rate
C. Prevalence rate
D. Design effect
Answer: B. Response rate
Rationale: The response rate measures participation among sampled
individuals. Here, the simple response rate is 800 ÷ 2,000 = 40%. A
3
, low response rate can introduce nonresponse bias if respondents
systematically differ from nonrespondents.
6. A researcher finds that counties with higher educational
attainment also have lower crime rates. The researcher concludes
that increasing education necessarily causes crime to decline. What
is the primary problem?
A. Reliability
B. Ecological fallacy and unsupported causal inference
C. Internal consistency
D. Instrument calibration
Answer: B. Ecological fallacy and unsupported causal inference
Rationale: County-level relationships do not necessarily apply to
individuals within those counties. Furthermore, an observational
correlation does not establish causation. Variables such as income,
employment, neighborhood characteristics, policing, and demographic
composition could contribute to the observed relationship.
7. Which statistic is most appropriate for describing the central
tendency of a highly right-skewed income distribution?
A. Mean
B. Median
C. Variance
D. Range
Answer: B. Median
Rationale: Income distributions are often positively skewed because a
relatively small number of individuals have very high incomes. The
mean can be disproportionately influenced by extreme values, whereas
