Given below are some statements. Read them carefully and choose the correct statement (s) from the given options.

Statement 1: . Spearman’s rank correlation gives a precise numerical value of the degree of linear relationship between two variables X and Y. 

Statement 2: When the variables cannot be measured precisely, Karl Pearson’s coefficient of correlation can be used to measure the linear relationship numerically.    

None of the given statement is correct.

The correct answer is Option 4: None of the given statement is correct.

Statement 1: . Spearman’s rank correlation gives a precise numerical value of the degree of linear relationship between two variables X and Y. This is incorrect. Karl Pearson’s coefficient of correlation gives a precise numerical value of the degree of linear relationship between two variables X and Y.

Statement 2: When the variables cannot be measured precisely, Karl Pearson’s coefficient of correlation can be used to measure the linear relationship numerically. This is incorrect.  When the variables cannot be measured precisely, Spearman’s rank correlation can be used to measure the linear relationship numerically.
