Answer #1

Linear correlation refers to a straight line relationship between two variables x and y in this case. The strength of that linear correlation relationship ranges from -1 to +1.

-1 means a perfect negative correlation between the 2 variables that is if X rises, Y decreases and when Y rises, X decreases.

+1 means a perfect positive correlation between the 2 variables that is if X rises, Y rises also and when Y decreases, X decreases also.

A correlation coefficient of 0 means no linear relationship between the 2 variables.
