Positive correlation = positive association Negative correlation = negative association
Are negative correlation and reverse correlation same?
No.
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
What is a negative correlation?
A negative correlation is a measure of the linear component of a relationship where one variable increase as the other decrease.
Is there a positive correlation a negative correlation or no correlation between daily newspaper circution and the number of television sets in homes?
I would assume a negative correlation. More TV sets per home = less newspaper circulation.

How can you tell from a scatter plot wheather two variables have a positive correlation a negative correlation or no correlation?
Positive correlation = the slope of the scattered dots will rise from left to right (positive slope) Negative correlation = the slope of the scattered dots will fall from left to right (negative slope) No correlation = no real visible slope, the dots are too scattered to tell.
