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 ρs.
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 ρs.
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 ρs.
C) Values near +1 do point to an uphill relationship between the two variables.
Therefore, all of the given choices are true.
