Question 1

With complete counterbalancing, order effects are dealt with by:

Accepted Answer

A)   randomly selecting two or three treatment orders for inclusion in an experiment.
B)   having treatment conditions presented in every possible order.
C)   summing them across treatment conditions.
D)   None of the answers is correct.

Question 2

In an experiment designed to study the effects of a drug on behavior, participants in the control group received a sugar pill rather than either the active drug or no drug. These participants constitute a:

Accepted Answer

A)   compound control group.
B)   placebo control group.
C)   blind control group.
D)   None of the answers is correct.

Question 3

In a matched-groups design, after selecting a sample of subjects, you:

Accepted Answer

A)   randomly assign subjects to your groups.
B)   select only the most intelligent subjects for inclusion in your research.
C)   match pairs of subjects on some measured characteristic (e.g., intelligence) , and randomly assign one member of each pair across experimental groups.
D)   None of the answers is correct.

Question 4

Which of the following is the most likely source of confounding?

Accepted Answer

A)   Two-way interactions
B)   Experimenter bias
C)   Carryover effects
D)   Fractional factorial designs

Question 5

A complete counterbalanced design is most practical in experiments:

Accepted Answer

A)   where carryover effects are a minimal problem to start with.
B)   where carryover effects can be totally eliminated with the proper counterbalancing procedures.
C)   with a small number of treatments.
D)   with a large number of treatments.

Question 6

The matched-groups design is most useful when:

Accepted Answer

A)   a randomized two-group design would be too time-consuming.
B)   you suspect that some subject characteristics are strongly correlated with your independent variable.
C)   you suspect that no relationship exists between subject characteristics and your dependent variable.
D)   you cannot manipulate independent variables.

Question 7

In a two-factor design, a simple main effect represents the effect of one independent variable at a given level of the other independent variable.

Accepted Answer

A) True 
 B)False
