The decision rule for a small sample sign test is based on a:
A) Binomial distribution.
B) Chi-square distribution.
C) Normal distribution.
D) F-distribution.

Question

Quizplus · Accepted Answer

The small sample sign test is a non-parametric test used when the normality assumption is not met. The decision rule in this test is based on counting the number of times a value in one sample is greater than or less than the corresponding value in the other sample. The distribution of the test statistic is approximated by the binomial distribution, and hence, option A is the correct choice.
