Exam 12: True Experiments, part 2: Factorial Designs

An advertiser is interested in the effects of color and size of containers on people's tendency to buy a certain brand of cereal.He prepares containers consisting of all combinations of color with size and asks each of a group of subjects which of the containers they would be most and least likely to buy.What type of design does this study represent?

Exhibit 12-1 Suppose a researcher investigated the judgments of guilt made by jurors in response to attractiveness (attractive vs unattractive)and facial expression (neutral vs smiling). Refer to Exhibit 12-1.The design can be described as a

Exhibit 12-2 The following information is used for the next 7 items A researcher performs an experiment and gets the following results Refer to Exhibit 12-2.Is there a main effect of A?

Factorial designs can be conducted

Graph the interaction of factor B,visual and audio presentation (via video)versus audio only presentation of course content,and Factor A,sex,from the following cell means on a standardized mid-term examination.Does there appear to be an interaction? Discuss your conclusions.

Exhibit 12-3 Suppose a researcher measured the test scores of college students who were taught chemistry in the presence of one type of music (country,rock,or classical)in one of three different colored classrooms (red,green,or blue). Refer to Exhibit 12-3.If a factorial design were used,what are the two independent variables?

If babies play longer with both blue and red fuzzy toys (as opposed to both blue and red smooth toys),then

Exhibit 12-3 Suppose a researcher measured the test scores of college students who were taught chemistry in the presence of one type of music (country,rock,or classical)in one of three different colored classrooms (red,green,or blue). Refer to Exhibit 12-3.The design can be described as a

Exhibit 12-1 Suppose a researcher investigated the judgments of guilt made by jurors in response to attractiveness (attractive vs unattractive)and facial expression (neutral vs smiling). Refer to Exhibit 12-1.If a two-factorial design were used,what are the two independent variables?

If neither Variable A nor Variable B has a main effect you can have

A factorial design that has at least one within-subject variable and one between-group variable is called a(n):

When two variables interact

An advertiser is interested in the effects of color and size of containers on people's tendency to buy a certain brand of cereal.He prepares containers consisting of all combinations of all 4 colors with all 3 sizes and asks each of a group of subjects to rate each of the containers for how likely they would be to buy it on a 1-9 Likert scale. a.What is the dependent variable? b.What type of design does this study represent? Be sure to give its full name. c.How many conditions would be possible? d.How many main effects would be possible? e.Are interactions possible?

Factorial designs involve

Exhibit 12-2 The following information is used for the next 7 items A researcher performs an experiment and gets the following results Refer to Exhibit 12-2.In order to tell if there is a main effect of B,you need to consider the

If one variable has a smaller effect when paired with higher levels of a second variable,you have a(n)

An interaction in which two independent variables tend to reverse each other's effects is referred to as a(n)

Bower,Gilligan,and Monterio (1981)hypothesized that people would notice and remember events in stories that were consistent with their mood.Participants were put into either a happy or a sad mood.All participants then read two stories,one of which was happy and one of which was sad.What was the design of the experiment?

Exhibit 12-3 Suppose a researcher measured the test scores of college students who were taught chemistry in the presence of one type of music (country,rock,or classical)in one of three different colored classrooms (red,green,or blue). Refer to Exhibit 12-3.The dependent variable is

Barnes,Ickes,and Kidd (1979)studied whether or not students would lend their notes to a classmate by varying the intentionality of the needy student (unintentional vs attentional)and the stability of their request (always vs sometimes).Participants received one request from one needy student.What was the design of the experiment?
