The Spearman rank-correlation is a nonparametric test that 1) uses the directions of differences observed in a matched-pairs sample to determine whether the relative frequency distributions of two statistical populations are identical to or different from one another and 2) determines whether a sample comes from a population with a specified median.

Spearman Rank-Correlation

A non-parametric measure of rank correlation, assessing how well the relationship between two variables can be described using a monotonic function.

Nonparametric Test

A type of statistical test that does not assume the data comes from a particular distribution.

Matched-Pairs Sample

A method where each subject is paired based on certain characteristics before being assigned to different treatments for comparison.

  • Comprehend the difference between parametric and nonparametric statistical tests concerning underlying data assumptions.

Final Answer :
False
Explanation :
The Spearman rank-correlation measures the strength and direction of association between two ranked variables, but it does not test for identical distributions or specify a population median.
