Answer 1

Answer: Which on of the following is NOT a situation appropriate for Sign Test?

Solution:

The sign test is a nonparametric test that can be used to test either a claim involving matched pairs of sample data, a claim involving nominal data with two categories, or a claim about the population median against a hypothesized value k.

Therefore, the situation not appropriate for Sign test is Claims about the median of a single population.

What would be considered to be a small sample for Sign Test?

For small sample size Sign test consider to be

Sample with n ≤ 25.

Which is the appropriate situations for Wilcoxon Signed-Ranks Test?

The Wilcoxon signed-rank test is a non-parametric statistical hypothesis for testing whether there is difference between two medians.

Therefore, the appropriate situations for Wilcoxon Signed-Ranks Test is Median of matched pairs.
