✔✔Koordeman et al. (2011) conducted a study on the effect of alcohol commercials on
alcohol consumption in a movie theater. Participants saw one of two types of beverage
commercials: alcoholic or nonalcoholic. Their consumption of alcohol during the movie
was then measured. Finally, they completed a questionnaire on their usual drinking
habits. Koordeman et al. found that young adults who generally consume large amounts
of alcohol each week were influenced to drink more alcohol when they saw alcohol
commercials, whereas the alcohol consumption of young adults who generally consume
small amounts of alcohol each week was not influenced by the type of commercial
shown. Which of the following is a factor in this study? - ✔✔type of commercial shown
✔✔A _______ design is one in which there are two or more independent variables. -
✔✔factorial
✔✔Interactions allow researchers to examine _________ variables. - ✔✔moderating
✔✔___________ are the means for each level of an independent variable, averaging
over levels of the other independent variable. - ✔✔Marginal means
✔✔In a 2 x 2 x 2 factorial design, what are all the possible effects to test? - ✔✔three
main effects, three two-way interactions, and a three-way interaction
, ✔✔A researcher wants to run a 2 x 3 mixed factorial design. The first factor is within-
subjects. The second factor is between-subjects. If the researcher wants 20
observations per cell, how many participants will he need in total? - ✔✔60
✔✔How many independent variables and how many cells are there in a 2 × 3 × 4
study? - ✔✔3 independent variables, 24 cells

alcohol commercial on alcohol consumption depended on whether the viewer was
usually a heavy drinker or a light drinker.
✔✔Yan and Sengupta (2011) examined the effects of price, attractiveness, and
consumer on the perceived tastiness and expensiveness of a dish of fried rice. The
study was a 2 × 2 × 2 design that varied price (inexpensive or expensive), picture
(attractive or unattractive), and consumer (self or classmate) in a between-subjects
design. What is the dependent variable? - ✔✔tastiness and expensiveness
✔✔Susan designed a study in which she had a group of younger adults (18-24 year-
olds) and older adults (50-65 year-olds). She had both groups recite a poem by memory
once in front of an audience of 50 people and once in a room by themselves. She
counterbalanced the order of these tasks between participants. She had the participants
rate their level of anxiety right before they recited the poem each time. What kind of
study design is this? - ✔✔mixed factorial design
