Strong and weak negative correlation
WebNegative correlation can be described by the correlation coefficient when the value of this correlation is between 0 and -1. The amount of a perfect negative correlation is -1. The strength of the correlation between the variables can vary. For example, suppose two variables, x and y, correlate -0.8. You can choose from many different correlation coefficients based on the linearity of the relationship, the level of measurementof your variables, and the distribution of your data.
