The randomized block design with exactly two treatments is equivalent to which of the following two-tailed tests?
A) independent samples z-test
B) independent samples equal-variances t-test
C) independent samples unequal-variances t-test
D) matched pairs t-test

Question

Quizplus · Accepted Answer

The randomized block design with exactly two treatments is equivalent to the matched pairs t-test, as each block is essentially a pair of individuals or objects that are matched based on a similar characteristic. Within each block, one individual receives one treatment and the other receives the other treatment, and the difference between their outcomes is used to test for a significant difference between the treatments. Therefore, the correct choice is D.
