why correlation cofficient always lies between 1 and -1
The correlation coefficient is symmetrical with respect to X and Y i.e.The correlation coefficient is the geometric mean of the two regression coefficients. or .The correlation coefficient lies between -1 and 1. i.e. .
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
No.
No. The units of the two variables in a correlation will not change the value of the correlation coefficient.
A correlation coefficient of 1 (r=1) is a perfect positive correlation.

That 5 is the cofficient of the term. The "n" is the variable!
Correlation is when two things are related or have similar properties. They can exist independently. Causation means that one thing made the other thing happen
5x 5 is the coefficient and x is the variable.

Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
