Explanation:

The correlation coefficient was used to show the relationship between two variables. A correlation could be negative, positive and zero correlation. A negative correlation and positive correlation both show the same relation between two variables but there is a difference that separates them.

Correlation coefficient range from -1 to +1. When correlation stands -1, indicates that the relationship between variables is negative. If the correlation stands between +1 then the relationship between two variables is +1 If the correlation is neutral it indicates that correlation is zero.
