Question 1

In a two-factor design, an interaction means that the effect of one factor depends on the levels of the second factor.

Accepted Answer

A) True 
 B)False

Question 2

Explain how a factorial study can combine between-subjects and within-subjects designs and why a researcher might want a mixed-design study.

Accepted Answer

A researcher can design a study with one

Question 3

A two-factor study compares the effectiveness of two different treatments (factor 1) by measuring performance before treatment, immediately after treatment, and three months after treatment (factor 2) for each participant. There are 100 participants, 50 are randomly assigned to treatment A and 50 to treatment B. The results from this study should be evaluated with mixed-design two-factor analysis of variance.

Accepted Answer

A) True 
 B)False

Question 4

In a two-factor study, it is possible to have one experimental factor and one nonexperimental factor.

Accepted Answer

A) True 
 B)False

C)  two; one 
D)  one; two 
A)  three; four 
B)  two; three 
C)  two; one 
D)  one; two

D)  Eight 
A)  Two 
B)  Three 
C)  Four 
D)  Eight

Question 7
