design.
more
fewer
the same
half as many
Question 2
pts

70–89 and found differences in men and women. In this example, gender of participant
was the __________.
between subjects variable.
within subjects variable.

,
Question 3
pts
Tamir et al. (2008) conducted a study to see what impact music has on participants
playing computer games. The researchers had participants play computer games while
listening to angry, exciting, and neutral music. The researchers then measured the
participant’s performance while listening to each type of music. This is an example of
what type of design?
between subjects design
within subjects design
between participants design
mixed subjects design
Question 4
pts
Katie is conducting a within subjects design. Her independent variable has 2 levels that
must occur 1 week apart. In the first session during the first week, Katie has 120
participants. However, a week later when the second session occurs, Katie only has 85
participants show up for the study. What disadvantage to within subject designs is Katie
encountering?
fatigue
attrition
practice effects
order effects
Question 5
pts
During the late 1980s and the early 1990s the Pepsi Challenge was in full swing. During
the challenge, participants were asked to taste cola from both Coke and Pepsi. Once
they had tasted both drinks, the participants were asked to report which was better
tasting. The results indicated that participants found Pepsi products to be better tasting.
What is the dependent
variable in this study?
Pepsi challenge
reported taste of the drinks
the different colas
the labels on the drinks
,Question 6
pts
We discussed a study known as the Stroop effect. Stroop developed 3 types of stimuli
for his study. Each type of stimuli presented a different task that participants had to
complete. Stroop then measured the amount of time it took the participants to complete
each task. What is the dependent
variable in this study?
the time to complete the task
the Stroop effect
the stimuli in the study
the three tasks
Question 7
pts
Which disadvantage to within subjects designs involves a participant dropping out of a
study or not returning to complete additional parts to a study?
caffeine
practice effects
statistical variance
attrition
Question 8
pts
Janiszewski and Uy (2008) conducted an experiment in which they had 43 participants
read 10 scenarios. All 43 participants each read all 10 scenarios. In this study, the
researchers wanted to determine the impact of the scenario type on the anchoring and
adjusting of participants. Anchoring and adjustment occurs when people use a starting
point (anchor) as a basis to make judgments about a given scenario (adjustment). This
is an example of what type of design?
between participants design
matched subjects design
within subjects design
between subjects design
Question 9
pts
Recall the research conducted by Bartlett et al. (2005) on the influence of action figures
on male body image. If Barlett exposed participants to the three conditions in the same
, manner and found that scores on the third condition always decreased, he might be
concerned about _________.
practice effects.
order effects.
presentation effects.
all of the above.
Question 10
pts
What kind of study uses a methodology in which participants are matched on a particular
characteristic before being assigned to the different levels of the independent variable?
mixed subjects design
within subjects design
matched subjects design
between subjects design
Question 11
pts
Carefully review the research matrix presented below. If this is a between subjects
design, how many total participants will be used in the experiment?
No Caffeine 8 Ounces 24 Ounces
10 participants 10 participants 10 participants
10
20

playing computer games. The researchers had participants play computer games while
listening to angry, exciting, and neutral music. The researchers then measured the
participant’s performance while listening to each type of music. What is the dependent
variable in this study?
types of music played during the study
the participant’s performance on the computer games
computer games
