WebApr 11, 2024 · The correlation coefficient for a perfectly negative correlation is -1. 2. Negative Correlation (-1≤ r <0) A negative correlation is any inverse correlation where an increase in the value of X is associated with a decrease in the value of Y. For a negative correlation, Pearson’s r is less than 0 and greater than or equal to -1.
