# Which of the following statements about the Spearman rank-correlation coefficient is true?

A) It is equal to the Pearson correlation coefficient of the ranks of the data.

B) The population Spearman correlation coefficient is labeled ρ_{s}.

C) Values near +1 point to an uphill relationship between the two variables.

D) All of these choices are true.

Spearman Rank-Correlation

An assessment of rank correlation, not based on parameters, which evaluates the extent to which two variables' relationship can be represented through a monotonic function.

Pearson Correlation

is a measure of the linear correlation between two variables, quantifying the strength and direction of their relationship.

- Identify the distinctions between diverse statistical tests and the situations in which they should be applied.
- Acknowledge the relationship between correlation coefficients and the force and pathway of relationships.

Final Answer :

D

Explanation :

A) It is true that the Spearman rank-correlation coefficient is equal to the Pearson correlation coefficient of the ranks of the data.

B) The population Spearman correlation coefficient is indeed labeled ρ

C) Values near +1 do point to an uphill relationship between the two variables.

Therefore, all of the given choices are true.

B) The population Spearman correlation coefficient is indeed labeled ρ

_{s}.C) Values near +1 do point to an uphill relationship between the two variables.

Therefore, all of the given choices are true.
