How do I find and interpret the linear correlation coefficient?
See explanation. I would suggest that you look it up in a book. Dictionary of mathematics perhaps.
This is one of those questions that is rather like: "how long is a piece of string".
It all depends on the structure of the relationship which has many variations. So it is hard to give a definitive answer.
Linea points to a fixed value coefficient.
Let the independent variable be
Let the dependant variable be
Let the correlation coefficient be
Then we have the general form of;
To find the value of
Again this is dependant on context. Basically it fixes the major relationship between the dependant and independent variables.
It could be described as a conversion factor
