The researcher looks at the number of tasks participants completed after being exposed to different types of settings (cluttered, organized) for different durations of time (short, long). The graph below depicts the results of the study. In this graph, which of the following effects is/are likely to be significant?

a Setting x Duration interaction only

Factorial designs are more informative than one factor designs because

allow us to observe interaction of two or more factors

Different participants are observed across the levels of ______, whereas the same participants are observed across levels of ______.

between-subjects factor, within subjects factor

A ____ factorial design is one in which each level of one factor is combined or crossed with each level of the other factor, with participants observed in each cell or combination of levels

complete

Which of the following is not a requirement for a between-subjects factorial design to qualify as an experiment?

control for order effects due to observing the same subjects in each group

IN a 2x2 table summary, where do you look to identify the main effects?

either row means or column means

A researcher manipulates the type of color used in a product line (bright, dark) and tests if the preference ratings for the product vary by gender. The quasi-independent participant variable is

gender

A researcher has participants rate two vignettes. Half are rating a man eating a healthy food and describing a women eating healthy food. The other half are assigned to rate the same vignettes, expect the man an woman are described as eating an unhealthy food in each vignette. In this example, the within-subject factor is:

gender of person described in the vignette

A researcher found that variations in the effects of one factor are influenced by, or depend on, the levels of the second factor. What the of effect did the research find?

interaction

Which of the following factorial experimental designs involved the manipulation of a between-subjects factor

mixed factorial & between-subjects

Which of the following is a type of factorial experimental design that includes at least one between-subjects factor and at least one within-subjects factor?

mixed factorial design

The "way" of a factorial design indicates:

number of groups in the design

The factorial experimental design includes the manipulation of

two or more independent variables

How are the conclusions we can draw in a factorial design limited when the design includes at least one quasi-in factor/

we do not show cause and effect for any effect that involves the quasi-in factor

Participants taste and rate each of four beverages that vary based on the type of flavor (familiar, unfamiliar) and sugar content (low, high). Assuming the type of flavor and sugar content are the two manipulated factors in this study, which type of factorial experimental design is illustrated in this example?

within subjects design

Which of the following is a common reason for adding factors to an experiment?

(all) build on previous research control for threats to validity enhance informativeness of interpretation

How many main effects are possible in a two-way factorial design?

2

A mixed factorial design has a between-subjects factor with four levels and within subjects factor with two levels. If 12 participants are observed in each group, then how many total participants were observed int he study?

48 part.

Which of the following identifies a higher-oder interaction that each letter identifies a factor?

A x B x C interaction
