January 8, 2024Question 17298 – NTA UGC NET Dec 2023 Paper-1
Given below are two statements:
Statement (I): Pearson’s coefficient of correlation ‘r’ is a very useful measure of the strength and direction of the relationship between two nominal variables.
Statement (II): Pearson’s coefficient of correlation ‘r’ always lies between 0 and 1
In the light of the above statements, choose the most appropriate answer from the options given below:
Correct Answer: D
Question 8 Explanation:
Statement I is incorrect because Pearson’s coefficient of correlation ‘r’ is typically used for measuring the strength and direction of the relationship between two continuous variables, not nominal variables.
Statement II is incorrect because the range of Pearson’s correlation coefficient ‘r’ is from -1 to 1, not 0 to 1. A correlation of 1 indicates a perfect positive linear relationship, -1 indicates a perfect negative linear relationship, and 0 indicates no linear relationship.
Statement II is incorrect because the range of Pearson’s correlation coefficient ‘r’ is from -1 to 1, not 0 to 1. A correlation of 1 indicates a perfect positive linear relationship, -1 indicates a perfect negative linear relationship, and 0 indicates no linear relationship.
