Definition of 'Negative Correlation'
A relationship between two variables in which one variable increases as the other decreases, and vice versa. In statistics, a perfect negative correlation is represented by the value -1.00, while a 0.00 indicates no correlation and a +1.00 indicates a perfect positive correlation. A perfect negative correlation means that the relationship that appears to exist between two variables is negative 100% of the time. It is also possible that two variables may be negatively correlated in some, but not all, cases.
