Why is naturalistic research NOT
useful in answering causal questions?
(a) The participants are not representative of a population.
(b) There is no observational variable.
(c) Naturalistic research does not seek relationships among
variables.
(d) It does not rule out alternative hypotheses.
In which of the following is
comparing a pretest-posttest difference score for experimental
and control groups a typical strategy?
(a) all experimental studies
(b) all quasi-experimental studies
(c) nonequivalent control-group designs
(d) between-subject designs
One of the problems in doing field
research is that
(a) participants are not available.
(b) random assignment of participants to groups is often
impossible.
(c) dependent measures cannot be taken.
(d) score data cannot be used and, therefore, use of ANOVA
is not possible.
Which of the following is similar
to a pretest-posttest design, but with more measures?
(a) ex post facto design
(b) general quasi-experimental designs
(c) program evaluation designs
(d) interrupted time-series design
Testing the external validity of
causal inferences that have been found in high-constraint
experimentation
(a) is one reason for doing field research.
(b) must be carried out in high-constraint laboratories.
(c) cannot be done.
(d) must be restricted to correlational research.
Baseline measures are taken
(a) before any manipulations are made.
(b) immediately following the manipulation.
(c) only on the experimental group.
(d) only on the control group.
If we wanted to determine if
hospital admissions for asthmatic attacks were related to air
quality, which of the following would be the most appropriate
design?
(a) ex post facto
(b) pretest-posttest
(c) interrupted time-series
(d) independent groups
Which of the following is true for
experiments in field settings?
(a) They cannot draw causal inferences.
(b) They can provide only observations of contingencies.
(c) They can allow causal inferences.
(d) They can generate hypotheses but not test them.
Under what conditions is history a
potential confounding factor?
(a) When the pretest measures are at an unusually high
level.
(b) When a disproportionate number of participants are lost
from one condition.
(c) When participant selection has been biased.
(d) When the study takes a fairly long time to complete.
In time-series designs, comparison
groups
(a) are not possible to include.
(b) are helpful.
(c) always include random assignment.
(d) cannot exceed two groups.
Which of the following is an
accurate statement about high-constraint, laboratory research?
(a) It has high internal validity but may have low external
validity.
(b) It is necessarily high in both external and internal
validity.
(c) It is so constrained that it has no external validity.
(d) It must include at least four groups for proper
controls.
Program evaluation research
(a) is a specific experimental design.
(b) is a group of research methods.
(c) is carried out under high-constraint, laboratory
situations.
(d) is diminishing in importance.
What term is used for designs that
are like experimental designs but not quite equal to them, and
from which we can still draw causal inferences?
(a) correlational designs
(b) differential designs
(c) quasi-experimental designs
(d) naturalistic-experimental designs
What is the term used for the
design in which a single group of participants is measured
several times both before and after an event or manipulation?
(a) single-subject design
(b) general quasi-experimental design
(c) between-subjects designs
(d) interrupted time-series design
In time-series designs, what are
the two major potential confounding factors that are difficult
to control without the addition of a comparison group?
(a) instrumentation and history
(b) regression to the mean and instrumentation
(c) history and attrition
(d) instrumentation and selection
What is the term used for the
potential confounding variable in a time-series study in which
the measuring procedures may be inadvertently changed over time?
(a) measurement error
(b) history
(c) instrumentation
(d) attrition
A survey is most useful in
gathering data on
(a) the knowledge base of participants.
(b) the attitudes of participants.
(c) the causes of participants behavior.
(d) both a and b
If you ask participants a survey
question such as, "What is your opinion of the way the economy
is being handled by the president?", this is an example of
(a) an open-ended question.
(b) a multiple-choice question.
(c) a Likert scale question.
(d) none of the above
If you want to get a representative
sample for a survey, you should use
(a) a probability sample.
(b) a nonprobability sample.
(c) a nonprobability sample from stratified groups.
(d) none of the above
The advantage of a stratified
random sample over a random sample is that
(a) stratified random samples require less work than random
samples.
(b) stratified random samples are more likely to accurately
represent a population because stratification on key variables
virtually assures accurate representation of those variables.
(c) the random sample is not a probability sample.
(d) stratified random samples provide both a probability and
a nonprobability sample in one procedure.
The smaller the sample size in a
survey study, the
(a) greater our confidence in the results.
(b) larger the confidence intervals around the population
estimates.
(c) smaller the confidence intervals around the population
estimates.
(d) more difficult it is to develop the survey instrument.
If you wanted to understand how
people's attitudes change over time and what factors contributed
to the change, you would want to use a
(a) cross-sectional design.
(b) between-subjects design.
(c) factorial design.
(d) longitudinal design.
