Chapter 11 FITB

Question 1

A factorial design uses all combinations of two or more — each having at least —

Answer 1

independent variables, two levels

Question 2

Factorial designs are employed when one wants to study the — of two or more independent variables.

Answer 2

joint effect

Question 3

A factorial design may save time by studying more than one condition per experiment, or it may be used when ruling out more than one rival hypothesis, or when one is interested in possible — between the independent variables

Answer 3

interaction

Question 4

In a factorial experiment, the — of one variable is the effect of that variable averaged over all the levels of the other variable

Answer 4

main effect

Question 5

An interaction exists between two independent variables when (independent) Variable A has a different effect on the dependent variable when it is combined with one level of (independent) Variable B than with another level of B. If the graph of a factorial experiment has — lines, there is an interaction between the variables.

Answer 5

nonparallel

Question 6

If there is an interaction, the — is uninterpretable unless the nature of the interaction is taken into account

Answer 6

main effect

Question 7

Types of interactions include

Answer 7

antagonistic, synergistic, and ceiling effect

Question 8

Factorial designs may be conducted as either— or — , or they may be used in mixed experiments that

have one within-subjects variable and one between-subjects variable

Answer 8

within-subjects or between- subjects experiments

Question 9

The — variable of a factorial design is experienced at all levels

by each subject. In contrast, each subject experiences only one level of a

Answer 9

within-subjects, between-subjects variable

Question 10

Controlling for potential – and — effects is important when

including a within-subjects variable in a factorial experiment

Answer 10

sequence and order

Question 11

The — factorial design requires the fewest subjects to achieve

a particular degree of power, the — the next fewest, and the — design the most

Answer 11

within-subjects, mixed design, between-subjects
