Question

identify which of these designs is most appropriate for the given experiment: completely randomized design, randomized block design, or matched pairs design. lunesta is designed to treat insomnia. in a clinical trial of lunesta, amounts of sleep each night are measured before and after subjects have been treated with the drug. the most appropriate design is design. options: completely randomized, randomized block, matched pairs

Explanation:

In a clinical trial for a drug (Lunesta) where we measure sleep before and after treatment, a matched pairs design is appropriate. Matched pairs design involves comparing two related groups (in this case, the same subjects' sleep before and after taking the drug), which fits the scenario of measuring the same subjects at two different times (pre - drug and post - drug sleep). Completely randomized design is for randomly assigning subjects to different treatment groups, and randomized block is for grouping similar subjects (blocks) and then randomizing within blocks, which are not as appropriate here as we are dealing with the same subjects' pre - and post - treatment measurements.

Answer:

matched pairs
