What is the MAIN factor lacking in a one-group pretest-posttest design?
a.
randomization
b. accounting for
maturation
c. assessing the effect of the
pretest
d. a control
group
Correct
What is the main flaw in the static group comparison experimental design?
a. The treatment is only given to one
group.
b. Selection bias alone ensures that there will be differences between
the two groups.
c. The experimental and control groups are given different
posttests.
d. There is no way to determine if the groups are equivalent prior to
treatment.
Correct
Which of the following experimental designs are considered3true experimental
designs?
a. randomized subjects, posttest-only control
group
b. between-
subjects
c. repeated
measures
d. Solomon three-
group
e. randomized matched subjects, posttest-only
control group
Correct
Although the3randomized subjects, post-test only3control3group3design lacks a pretest,
it can still ensure valid comparisons mainly because of its use of:
a. only one dependent
b.
randomization.
c. a control
group.
d.
matching.
Correct
What is the main advantage of the randomized matched subjects, posttest-only control
group design?
a. There is no
pretest.
b. It can be used with small
samples.
c. Groups are
randomized.
d. The samples are
unbiased.
Correct
Solomon's experimental designs are characterized by the addition of one or more
unpretested groups.
3a.
True
3b.
False
Correct
Which of the following are advantages of a factorial design?
a. capacity for assessing interaction
effects
b. determining the main effects for each independent
variable
c. accomplishing more with only one
experiment
d. the effect of treatment on different groups of subjects is
e. use of multiple control
groups
Correct
A between-subjects design tests a treatment on only one group of participants.
3a.
True
3b.
False
Correct
Which of the following are true of quasi-experimental designs?
a. They are sometimes necessary because of the nature of real
situations.
b. Their main drawback is the lack of
control.
c. Subjects are not randomly assigned to treatment
groups.
d. They do not involve manipulation of an independent
variable.
e. They do not make it possible to reach valid
conclusions.
Correct
Which of the following make time-series designs different from other experimental
designs?
a. They include control
groups.
b. They involve periodic
measurements.
c. They carry a greater possibility of testing
effects.
d. They control for history
e. They can rule out maturation
effects.
Correct
Which of the following are topics of study that are especially suited to the single-
subject experimental design?
a. whether there is an interaction between anxiety and performance
expectation
b. the changes in children's test scores after
physical exercise
c. the value of a treatment to autistic
children
d. the effects of a treatment to students' attitudes toward
learning math
e. how students with oppositional defiant disorder respond to a relaxed classroom
environment
Correct
Single-subject experimental designs can have particular difficulty meeting external
validity requirements.
3a.
True
3b.
False
Correct
