Answer #1

Answer:- The correlation coefficient is a statistical measure of the strength of the relationship between relative movements of two variables. The range of correlation coefficient lies between -1 to 1. A calculated number greater 1.0 or less than -1.0 means that there was an error in the correlation measurement. A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation. A correlation of 0.0 shows no linear relationship between the movement of two variables.

If we denote correlation coefficient by 'r' then -1< r <1.
