Quizplus · Accepted Answer

The randomized block design is a type of experiment where subjects are divided into blocks based on some shared characteristics, and then randomly assigned to different treatments within those blocks. In a design with exactly two treatments, this is equivalent to a matched pairs t-test, where each subject receives both treatments in a random order. Therefore, the best choice is D, the matched pairs t-test.
