Question

Quizplus · Accepted Answer

The randomised block design with exactly two treatments involves pairing each block (subject) with themselves and randomly assigning one treatment to one of the pairs and the other treatment to the other pair. Therefore, this design is equivalent to a matched pairs t-test, which is the only option that involves paired data. The other options involve independent samples, which is not the case in a randomised block design with exactly two treatments.
