If the variables have a negative association, then their correlation must be between -1 and 0. Correlation values range from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation. A negative association means that as one variable increases, the other variable tends to decrease. Therefore, the correlation coefficient will be negative. However, it cannot be less than -1, as this would indicate a stronger negative association than is possible.
