Question

which of these statements is true for a matched-pair design? a.) the matched pair subjects are randomly assigned, both subjects to the treatment or both to the control. b.) the matched pair subjects are randomly assigned to the same treatment. c.) the matched pair subjects are assigned to either treatment or control in order to allow for comparisons across pairs. d.) the matched pair subjects are randomly assigned, one member to the control and the other to the treatment.

Answer 1

The true statement for a matched-pair design is that subjects are randomly assigned, one to the treatment and the other to the control, enabling comparisons within pairs. Therefore correct option is D

Step-by-step explanation:

In a matched-pair design, each subject in a pair is randomly assigned to different conditions, typically one member to the treatment and the other to the control. The correct statement for a matched-pair design is d.) the matched pair subjects are randomly assigned, one member to the control and the other to the treatment. This design facilitates comparison within each pair, which is particularly useful when dealing with small sample sizes or when trying to control for potential confounding variables.
