Because the distribution of rank-order scores is known exactly rather than estimated, rank-order tests:
A)do not require estimating any parameters
B)are used in most real studies
C)are almost always preferred over square-root transformations
D)require drawing additional samples

Question

Quizplus · Accepted Answer

Rank-order tests do not require estimating any parameters because the distribution of rank-order scores is known exactly. Therefore, option A is the correct choice. Option B is incorrect because rank-order tests may not be necessary or appropriate for all studies. Option C is incorrect because it is not always the case that rank-order tests are preferred over other transformation methods. Option D is incorrect because rank-order tests do not require drawing additional samples.
