Which of the following concerns leads researchers to balance practice effects in repeated measures designs?
A)Balancing practice effects allows researchers to determine the sources of systematic error variation in repeated measures designs.
B)Balancing practice effects allows researchers to account for individual differences variables in repeated measures designs due to participants' prior experience.
C)Balancing allows researchers to ignore sources of confounding that cannot be balanced in repeated measures designs.
D)Balancing allows researchers to control changes participants undergo with repeated testing in repeated measures designs.

Question

Quizplus · Accepted Answer

Balancing practice effects allows researchers to control changes participants undergo with repeated testing in repeated measures designs. This is important to eliminate the influence of individual differences due to prior experience and to ensure that any changes observed in the outcome variable are due to the manipulation of the independent variable and not to practice effects. The other answer choices are incorrect as they do not accurately reflect the purpose of balancing practice effects in repeated measures designs.
