Correlation coefficients are used to measure the strength, like weaker or stronger relationship between two variables.
The correlation coefficient is a unit less number and must always lie between –1.0 and +1.0, inclusive.
The correlation coefficient, r , gives us information about the strength and direction of a linear relationship between any two variables. We can say that r > 0 is a positive correlation and r < 0 is negative. |r| closer to 1 is a stronger correlation.
The larger r is in absolute value, the stronger the relationship is between the two variables.
