Given below are two statements:
Statement (I): Spearman’s rho ($\rho$) is generally used to measure the strength and direction of the relationship between two ordinal variables.
Statement (II): Pearson’s correlation coefficient ‘r’ is quite useful when the relationship between two variables is curvilinear.
In light of the above statements, choose the most appropriate answer from the options given below:
- A.
Both Statement I and Statement II are correct
- B.
Both Statement I and Statement II are incorrect
- C.

Show answer & explanation
Correct answer: C
Statement I is correct: Spearman’s rho is designed to measure the strength and direction of monotonic relationships between two ordinal variables. Statement II is incorrect: Pearson’s correlation coefficient 'r' measures linear associations only and is not suitable for curvilinear relationships.
