Quizplus · Accepted Answer

The related-samples design is used when the same group of participants is tested under two different conditions. This design has several advantages, such as being more practical and increasing the power of a research study. Additionally, this design can minimize standard error, as it uses the same group of participants for both conditions. However, it does not increase variability, as it is measuring the same group of individuals. Thus, option (D) is the correct answer, as it is the only option that is not an advantage of the related-samples design.
