Question 1

Which of the following is NOT a method for trying to prevent a participant characteristic (such as age or gender) from becoming a confounding variable in a between-subjects experiment?

Accepted Answer

A)  Hold the participant characteristic constant.
B)  Randomly assign participants to treatment conditions.
C)  Randomly select the participants from the population.
D)  Match the groups with respect to the participant characteristic.

Question 2

Randomizing a variable across treatments guarantees that the variable cannot become a confounding variable.

Accepted Answer

A) True 
 B)False

Question 3

In a between-subjects design,large individual differences can lead to

Accepted Answer

A)  large variance within treatments.
B)  small variance within treatments.
C)  several independent variables.
D)  several dependent variables.

Question 4

An advantage of holding a variable constant rather than using random assignment to form your groups is that

Accepted Answer

A)  holding a variable constant reduces error due to participant differences.
B)  holding a variable constant is easier than randomization.
C)  holding a variable constant guarantees that there is no systematic relationship between participant characteristics and the treatment conditions.
D)  holding a variable constant ensures a nonbiased sample.
